Primum Non Nocere*

November 28th, 2011

Many media outlets are reporting on the removal of a 200 lb. 8 year old from his family in Cleveland. Cleveland is, of course, the home of Toby Cosgrove, MD, head of the Cleveland Clinic, who proclaimed his desire to not hire workers who were obese. This came a year or so after the American Medical Association took the official position that persons who are obese are not entitled to compensation for being disabled for being unable to work. 

The intellectual justification for the forced removal of the child from his family is that provided by Dr. David Ludwig of Harvard Medical School.  State Intervention in Life-Threatening Childhood Obesity, July 13, 2011, Murtagh and Ludwig 306 (2): 206 — JAMA In the Commentary in July in the Dr. Ludwig had indicated that the forced removal by the state of children who were obese was justified. 

On what basis, you might ask? Well, there were several and they were all, in my opinion, intellectually bankrupt.

First, Dr. Ludwig and his co-author Lindsey Murtagh, J.D., assume “even mild parenting deficiencies such as having excessive junk food in the home or failing to model a physically active lifestyle, may contribute to a child’s weight problem.”

Excuse me? Before you go calling these “parental deficiencies,” how about defining: “excessive”, “junk food” or “failing to model a physically active lifestyle? Well, forget about it. They don’t define their terms.

What do they mean by “may contribute” to a child’s weight problem? If you are arguing that these “mild parental deficiencies” cause life-threatening conditions, is “may” good enough? What is the degree of evidence? If you are arguing that these conditions merit breaking up a family should not the evidence be like, beyond a reasonable doubt or a preponderance of the evidence? Is “may” good enough?

Second, they posit that severe obesity (a BMI at or beyond the 99th percentile) represents a fundamentally different situation than most overweight and obese children who have “the opportunity to ameliorate these risks through behavior change and weight loss as adults.” So, they say that severe obesity is fundamentally different “suggesting profoundly dysfunctional eating and activity habits”. Obesity of this magnitude can cause immediate and potentially irreversible consequences, most notably type 2 diabetes”.

Excuse me? Where is it written that persons with severe obesity as a child have a much smaller likelihood of reversing it as an adult than those with a lower level of obesity?

And what makes the BMI, which we know is a limited measure of body adiposity, at the 99th percentile different from the 97th percentile or the 95th percentile or the 92nd  percentile for that matter?

They argue that  severe obesity ‘suggests’ profoundly dysfuncitional eating and physical activity habits? ‘Suggests?’ They aren’t sure? If they are proposing breaking up a family maybe something more than ‘suggests’ is warranted. More importantly, could it not be that we are confusing cause and effect.  If there is anything to the increases in height and weight over the past 350 years, if there is anything to the contribution of genetic inheritance to obesity, if there is anything to the contribution of epigenetic factors to obesity, then, we must at least allow the suggestion that some children are born programmed to be overweight or obese. Upon achieving that status, one would assume they would overeat and underexercise compared to their normal weight peers. Would these be acquired ‘habits’ or the adaptions to their body habitus?

When they say that obesity of this magnitude can cause immediate and potentially irreversible consequences, most notably type 2 diabetes, what do they mean? Only a subset will develop type 2 diabetes immediately and for many, it will be manageable by lifestyle, drugs or surgery. Others, at a BMI lower than the 99th percentile and some who are merely overweight or normal weight will develop diabetes as well.

Third, (here’s the rub) the authors point with alarm that these patients may have to have bariatric surgery, whose long-term safety and effectiveness is not established. Therefore, they propose an alternative “therapeutic approach” i.e., placement of the severely obese child under state protective custody. The authors state, “Indeed, it may be unethical to subject such children to an invasive and irreversible procedure without first considering foster care.”

Doh? Did I get this right? Because at some point in the future, a child has continued to suffer with obesity and decides to have bariatric surgery, Ludwig and Murtagh propose the state comes in when the child is a juvenile and break up the only family the child has ever known?

Friends, I have worked for years with the professional jealousy of surgeons and internists and non-physician health care professionals. For the most part, they keep these often bitter inter-professional competitions to themselves. But this approach of Ludwig and Murtagh is nothing more than saying that breaking up a family, taking an obese child away from their mother and father and siblings, making them a ward of the state, having them raised by strangers who are paid for their care is better than even the potential that someday that person may want/be eligible for/can pay for bariatric surgery. 

The bias is demonstrated by the additional point raised by the authors that, “Although removal of the child from the home can cause families great emotional pain, this option lacks the physical risks of bariatric surgery. Moreover, family reunification can occur when conditions warrant, whereas the most common bariatric procedure (Roux-en-Y anastomosis [gastric bypass]) is generally irreversible.” Well, this is factually wrong. Roux-en-Y is not the most common bariatric procedure. The reversible laproscopic gastric banding is. Metabolic/bariatric surgery Worldwide 2008. [Obes Surg. 2009] – PubMed – NCBI  And  emotional pain may play a  particularly important role on the development of obesity. See this recent post.

And what does family reunion “when conditions warrant” mean? There are several options here which are starkly different and completely unaddressed by the authors. One option is that the obese child has returned to normal weight. The second option is that the obese child is still obese or has lost some weight but has improved eating or physical activity behaviors. The third option is that one parent or both have improved their ‘deficiencies’ by (a) removing only ‘excessive’ junk food in the home and/or (b) modeling a physically active lifestyle, independent of any change in the child. (Did I mention that the NIH guidelines for pediatricians on weight management did not find much support for physical activity?)

The fourth option is that that the foster care parents are both removing excessive junk food and modeling a physically active lifestyle and the child is continuing to gain weight. In some cases, there may be no “family reunification” but a succession of foster homes, all equally unable to affect the child’s excess adiposity. 

At the very end of their Commentary, Ludwig and Murtagh do a bit of a CYA, stating, “Nevertheless, state intervention would clearly not be desirable or practical, and probably not be legally justifiable, for most of the approximately 2 million children in the United States with a BMI at or beyond the 99th percentile. Moreover, the quality of foster care varies greatly; removal from the home does not guarantee improved physical health, and substantial psychosocial morbidity may ensure. Thus, the decision to pursue this option must be guided by carefully defined criteria such as those proposed by Varness et al with less intrusive methods used whenever possible.”

Now, dear reader, when one comes upon a statement like this, one assumes that Varness, et al, is in at least broad agreement with Ludwig and Murtagh. So it came as some surprise to actually read the cited Varness articles. See Childhood obesity and medical neglect. [Pediatrics. 2009] – PubMed – NCBI 

What Varness says is that, for a child to be removed from their home, all 3 of the following criteria have to be met: (1) a high likelihood that serious imminent harm will occur; (2) a reasonable likelihood that coercive state intervention will result in effective treatment and (3) the absence of alternative options for addressing the problem.

Regarding #1, a high likelihood that serious imminent harm will occur, Varness states, “The mere presence of childhood obesity does not predict serious imminent harm…Although childhood obesity is a risk factor for the development of multiple diseases as an adult, increased risk for adult diseases does not constitute serious imminent harm.” At the other end of the spectrum are current risks, such as severe obstructive sleep apena with cardiorespiratory compromise, uncontrolled type 2 diabetes and advanced fatty liver disease with chirrhosis. In some cases, like advanced hepatic fibrosis, the harm cannot be reversed in adulthood. Varness et al state, contrary to Ludwig and Murtagh, “There is no clear threshold level of childhood obesity (overweight, obese, or severely obese) that automatically predicts serious imminent harm….Although it is true that childhood obesity can lead to adult obesity, childhood obesity itself does not seem to lead to irreversible changes that are significant enough to mandate coercive state intervention.”

Regarding #2, a reasonable likelihood that coercive state intervention will result in effective treatment, Varness states, “In other words, is it truly reasonable to demand that families be able to achieve effective weight loss for their children? In addition, if it has been impossible for a family to reduce weight, what evidence is there to suggest that removal from the home would be more successful?” 

Regarding #3, the absence of alternative options for addressing the problem, Varness clearly does not share Ludwig and Murtagh’s antipathy for bariatric surgery. He states, “In summary, medications and surgery hold some promise but still have a questionable risk/benefit ratio, in both the short term and the long term. Although these may seem to be attractive options for some motivated adolescents with severe obesity, they are not options that are likely to be mandated for a child over the family’s objections. In contrast to the Ludwig-Murtagh paradigm of “mild parenting deficiencies,” Varness observes, “ In most cases of obesity, families make a good-faith effort to address the problem when they are made aware of the condition and the potential adverse health consequences. The development of a serious comorbidity can serve as a “wake-up call” for families, prompting full cooperation with intensified medical services.”

In sum, Varness makes the case that state intervention for obese children with no comorbidity is not justified; for those with a serious imminent harm, e.g. obstructive sleep apnea with cardiorespiratory compromise, intervention is probably justified. In between, only those risks known to be irreversible as an adult, such as hepatic fibrosis resulting from nonalcoholic fatty liver disease as opposed to cardiovascular disease, seems to be justified.

Finally, contrary to the misinformation about bariatric surgery, Varness notes that, “If a medical or surgical intervention that has a very high probability of decreasing weight with minimal adverse events is developed, then the availability of this effective treatment might result in a stronger intervention on behalf of children. For instance, gastric banding is a reversible procedure that involves the laparoscopic placement of an adjustable band around the proximal stomach. This procedure is not approved by the Food and Drug Administration for adolescents, and long-term data on its efficacy and complications are lacking. However, this procedure may hold some promise for extremely obese children, particularly as it is reversible.” In other words, coercive state action may be justified for bariatric surgery, rather than as an alternative to bariatric surgery, as desired by Ludwig and Murtagh. Not to belabor the point, but it seems Varness contradicts every major point Ludwig and Murtagh make. Curious, no?

My problem with the Ludwig-Murtagh commentary is not just on its intellectually bankruptcy and the harm it is bringing on persons who have enough pain it their lives. It is the question of what is Organized Medicine doing? So the position of Organized Medicine is this: Persons with obesity should be denied jobs (and, presumably, employer-provided health care), denied disability compensation when they cannot work, empathetic treatment by their physician and now the support of their own families in favor of unknown, paid-to-be-parents in foster care? Shouldn’t medicine be looking for better treatments? Maybe diagnosing their own patients? Maybe making appropriate referrals? Why don’t Dr. Ludwig and Attorney Murtagh call on pediatricians to develop better treatment protocols for children and adolescents with obesity? Why don’t they call on the American Academy of Pediatrics to lobby for dedicated funding for research on new treatments? Why don’ they criticize their fellow pediatricians who neglect to advise their patients on weight loss, in my opinion, unethically so. Pediatricians, in particular, have spent decades telling parents their children will ‘grow out of’ their weight problems. Now that obesity has become epidemic, they have done next to nothing to actually treat the disease, instead pointing to food companies’ marketing, television viewing, computers, vending machines, and parents as the culprits. Is it too much to ask them to develop treatments for their patients and quit blaming everyone else?

This blaming is only driving parents away from consulting with primary care providers, as discussed in Dr. Arya Sharma’s blog today. www.drsharma.ca.



If medicine, and especially, pediatrics, cannot help, at least stop making matters worse.

Unspoken: The Childhood Sexual Abuse – Obesity Connection

November 14th, 2011

For the past week, shocking news has come out of Penn State University of alleged child sexual abuse by a former football defensive coach, Jerry Sandusky. The scandal has taken down the university’s president and its famed head coach, Joe Paterno. The school’s credit rating has been downgraded;  federal and state agencies are investigating.

Most of us react to such news with a sickening feeling of the psychological trauma the victims of such abuse, in this case including a 10 year old boy, must endure. Less well researched is the connection between child sexual abuse and adult diseases including mortality.

In 1998, Felitti et al. published a paper on the relationship of childhood abuse and household dysfunction to the leading causes of death in adults. Their study included children who were exposed to psychological, physical or sexual abuse, violence against the mother, living with household members who were substance abusers, mentally ill or suicidal or ever imprisoned. They founded a graded relationship between the number of categories of childhood exposure and adult health risk behaviors. Persons who had experienced four or more categories of exposure, compared to none, had a 4-fold to 12-fold increase in health risks for alcoholism, drug abuse, depression and suicide attempt; a 2-4 fold increase in smoking, poor self-reported health, over 50 sexual partners and sexually transmitted disease; and a 1.4 to 1.6 fold increase in physical inactivity and severe (over BMI of 35) obesity. They found, “The seven categories of adverse childhood experiences were strongly interrelated and persons with multiple categories of childhood exposure were likely to have multiple health risk factors later in life.” Relationship of childhood abuse and household … [Am J Prev Med. 1998] – PubMed – NCBI

The author, Dr. Vicent J. Felitti, was with the Southern California (Kaiser) Permante Medical Group. In 2010, he and colleagues authored another paper on medical group’s Positive Choice Weight Loss Program. The program was achieving remarkable success with a combination of absolute fasting and a group program to explore the basis of each participant’s unconscious use of food and to explore the hidden benefits of obesity for the individual. Yes, the benefits of obesity.

The group found that their ability to quickly bring about significant weight loss was frustrated by the high dropout rate of persons who were successful or who sabotaged their own efforts. They took detailed life histories of 286 patients. Writes Dr. Felitti, “Here, we unexpectedly discovered that histories of childhood sexual abuse were common, as were histories of growing up in markedly dysfunctional households. It became evident that traumatic life experiences during childhood and adolescence were far more common in an obese population that was comfortably recognized. We slowly discovered that major weight loss is often sexually or physically threatening and that obesity, whatever its health risks, is protective emotionally…The antecedent life experiences of the obese are quite different from those of the always-slender. “ A bit later, he notes, “By the mid-1980s, we had learned that our initial goal of teaching people to “eat right” was totally irrelevant to obesity, although it seemed a reasonable thing to do when we did not know what to do.” The group found that for many participants, obesity is beneficially protective: sexually, physically and socially. A woman who had rapid weight gain was raped at age 23 and subsequently gained 105 lbs. She said, “Overweight is overlooked, and that’s the way I need to be.” Finally, the program found two major predictors of weight regain: a history of childhood sexual abuse and currently being married to an alcoholic (generalizable to having a significantly dysfunctional marriage).  Obesity: Problem, Solution, or Both? 

A recent review of the published literature on interpersonal violence and obesity seems to bear out Dr. Felitti’s research. Reviewing 36 separate studies, A.J. Midei and K.A. Matthews found 81% of the studies reported a significant positive association between some type of childhood interpersonal violence and obesity, although 83% of the studies were cross-sectional. Associations were consistent for caregiver physical and sexual abuse and peer bullying. Mechanisms were not clearly identified although anger, stress, depression, sadness and loneliness were cited. Interpersonal violence in childhood as a risk facto… [Obes Rev. 2011] – PubMed – NCBI 

Perhaps, then, it should not be a surprise to find a high prevalence of patients with histories of childhood sexual abuse seeking bariatric surgery. Sexual abuse survivors and psychiatric hospitaliza… [Obes Surg. 2007] – PubMed – NCBI and childhood sexual abuse +bariatric surgery – PubMed – NCBI and Childhood maltreatment in extremely obese male and … [Obes Res. 2005] – PubMed – NCBI.

The point is that we, as a society, are just beginning to understand the devastation childhood sexual abuse can cause on the human psychological and physiological systems. We also need to realize that the person with obesity, so often scorned, isolated and penalized, may well be the adult survivor of unspeakable childhood trauma.

Cancer and Obesity Explored

November 3rd, 2011

The Institute of Medicine’s National Cancer Policy Forum this week convened a two-day workshop, “The Role of Obesity in Cancer Survival and Recurrance.” So this is a good opportunity to re-visit the relationship between these two deadly diseases. Susan Gapstur of the American Cancer Society noted the growing list of cancers associated with obesity. For men, these include cancers of the colon, esophagus, kidney, colorectum, pancreas, gallbladder and liver. Women are affected by the same cancers as well as of the endometrium and postmenopausal breast cancer. Evidence is accumulating for an association with non-Hodgkin’s lymphoma, ovarian cancer in women and aggressive prostate in men. Obesity, she pointed out, is not the second (to tobacco) leading risk factor of cancer. Ominously, she pointed out we do not know what the health effects will be for the children now obesity who will obese for a lifetime.

Pamela J. Goodwin of the University of Toronto explored potential mechanisms in the progression to cancer including inflammation, adipokines, hyperinsulinemia, diabetes/diabetes drugs and sex steroids. She pointed to studies showing reductions in cancer risk with intentional weight loss of 20 pounds or more.

Rachel Ballard-Barbash of the National Cancer Institute, who has been a leader in exploring the obesity-cancer connection for many years, moved the discussion to look at the co-morbid conditions of obesity and their relationship to cancer mortality, including renal disease, congestive heart failure, cerebrovascular disease, citing A refined comorbidity measurement algorithm fo… [Ann Epidemiol. 2007] – PubMed – NCBI

Patricia Ganz of the UCLA Schools of Medicine picked up the point and explained that about half of all deaths of breast cancer survivors are due to causes other than breast cancer. She recommended prevention of weight gain and/or weight loss in those breast cancer survivors who are obese. 

Thomas Wadden described the non-surgical approaches to weight loss used in the Diabetes Prevention Program and the LOOK Ahead study and the contribution of intensive behavioral counseling to reduction in comorbid conditions associated with obesity

AHRQ Seeking Comments on Bariatric Surgery

October 21st, 2011

The federal Agency for Healthcare Research and Quality is seeking comments on an evidence report comparing bariatric surgery to other modes of treating adults with obesity with a BMI between 30 and 35 with metabolic comorbidities, such as type 2 diabetes. The draft report finds moderate strength evidence for Roux-en-Y, laproscopic gastric banding and sleeve gastrectomy for resolution of type 2 diabetes at least in the short term.

The comment period is open to November 16, 2011. See Research Available for Comment | AHRQ Effective Health Care Program

Book Review: Fat Shame by Amy Erdman Farrell

June 18th, 2011

Book Review: 

“Fat Shame; Stigma and the Fat Body in American Culture” by Amy Edrman Farrell, New York University Press, 2011

This book, by the John and Ann Curley Faculty Chair in Liberal Arts at Dickinson College in Pennsylvania, might have made an important contribution to our understanding the origin and expression of stigma against persons with obesity. Unfortunately, it does not.  It is basically one long membership brochure for the National Association To Advance Fat Acceptance (NAAFA). Nothing wrong with that in itself. But for a college professor I think we could expect a little fact checking and critical thinking. The author lays out her  major points and all are wrong. They are:

  1. The  “Obesity Epidemic” is all hype;
  2. It is the hype about the obesity epidemic which causes fat stigma;
  3. The health effects of obesity are exaggerated or fabricated;
  4. The colossal weight loss industry fuels stigma and phony health claims;
  5. The commercial interests started stigmatizing persons with obesity in the late 19th Century;
  6. This industry lead  people to futile and dangerous diets and surgery;
  7. But there is an  answer in the Healthy-At-Every-Size  program.

#1  The Obesity Epidemic is all hype

Farrell repeatedly puts quotation marks around obesity epidemic, (as in “obesity epidemic”) to indicate her derision  or skepticism for the concept. She writes, “With its connotations of disease, contagion, and proliferation, the choice of the term “epidemic” is deliberately alarmist, suggesting imminent danger and sure catastrophe if not addressed. (At p. 9) Her footnote  instructs us, “Epidemic is a technical term from the field of epidemiology that refers to a disease found at levels higher than expected. In common usage, however, it refers to an infectious disease.”

Comment: Farrell implies by the use of these quotation marks that she doubts the credibility of the obesity epidemic. In fact, the news stories and comments of health experts come from epidemiologists, primarily but not exclusively at the United States Centers for Disease Control and Prevention which reported repeatedly on the epidemic of obesity in the late 1990s onward. See The continuing epidemics of obesity and diabetes i… [JAMA. 2001] – PubMed result and The spread of the obesity epidemic in the United S… [JAMA. 1999] – PubMed result  In fact, searching the National Library of Medicine on-line database, PubMed, one finds nearly 4,000 scientific articles under the search term “obesity epidemic.” So the source of these alarmist views are the very same epidemiologists we rely on for our information about  cancer, HIV/AIDs, smoking, the flu, heart disease.

Her point about “epidemic” commonly being used to refer to infectious diseases misses the point entirely. What the epidemiologists were pointing out by using “epidemic” was exactly this: we were witnessing a unique phenomenon of a non-communicable chronic disease increasing at rates previously only seen in infectious diseases. The then director of CDC, Jeffrey Koplan said in 1999, “Obesity is an epidemic and should be taken as seriously as any infectious disease epidemic.” CDC Media Relations: Obesity epidemic increases dramatically in the United States: CDC director calls for national prevention effort, Released October 26, 1999

Farrell does not directly challenge any of the data about the epidemic only implies disbelief. In fact, the evidence of a sharp, upward spike in the prevalence of obesity in the United States in the later half of the 20th Century justifies the use of the term epidemic.

Katherine Flegal, the CDC epidemiologist responsible for much of the work on obesity over the past 20 points to ample justification for the use of the term “epidemic.” Commentary: the epidemic of obesity–what’s in a n… [Int J Epidemiol. 2006] – PubMed result.  Kim and Popkin also point out the rise of obesity across the world, including developing countries. Commentary: understanding the epidemiology of over… [Int J Epidemiol. 2006] – PubMed result

#2 It is the hype about the obesity epidemic that is the cause of stigmatization

Lest she wastes any time discussing whether the obesity epidemic is real or not, Farrell quickly moves on to note that similar “troubling, alarming headlines constitute what other scholars, in their work on AIDs and the HIV virus, describe as apocalyptic thinking. Such thinking not only clouds judgment, it also induces a moral panic about the guilt of the one who “causes” such a catastrophe, often leading to extraordinary and discriminatory action on the basis of “health” and “well-being”. This kind of apocalyptic thinking has justified our national “war on fat” which began with Surgeon General C. Everett Koop in the 1990s.” (At p.9)

Comments:  Such thinking only clouds judgment if it is wrong. If you see flames and smoke coming out of your neighbor’s house,  it is not apocalyptic thinking to yell “Fire!” That is what happened with obesity and with HIV/AIDs. Does such thinking induce a moral panic about the guilt of the one causing such a catastrophe? Without doubt, the answer is yes. Is that the whole story? Without doubt no. We witnessed at the outbreak of the HIV/AIDs epidemic a similar kind of moral backlash. Witness the Ryan White story. Ryan White – Wikipedia, the free encyclopedia. As harmful and repulsive as individual stories can be, societies can be educated and change, legal protections can be put in place and societal pressure can change behavior if not attitudes. This is also true on the “war on cancer”.  Cancer used to be heavily stigmatized as well. In both cases of HIV/AIDs and cancer, public responses of research, prevention and treatment included effective campaigns addressing public understanding and combating stigmatization and discrimination.

Like police around a crime boss’s lair, Farrell surrounds health and well-being with those pesky quotation marks. Is she implying that HIV/AIDs does not affect health and well-being or that obesity does not? Or she saying you can only have it one way: ignore the disease and avoid the stigmatization? Would ignoring HIV/AIDs or obesity have avoided cases of stigmatization of gays and lesbians or would ignoring the growth in the prevalence and understanding of  obesity meant that people would not make fun of persons with obesity? Possibly, but I don’t think it so easy.

#3  The health effects of obesity have been exaggerated if not misrepresented .

Farrell again quickly switches to another topic. She writes, “While references to the “obesity epidemic”  are themselves pandemic, not all health experts agree on the physical dangers of fatness.  As Eric Oliver discusses in Fat Politics, it was not until the 1990s that U.S. agencies and medical organizations began to discuss obesity as a “disease,” a designation that legitimated tremendous amount of money spent in research and treatment. Indeed, most reports arguing for the status of “disease,” it turns out, were written – or ghostwritten- by those with a large financial stake in research: pharmaceutical and medical firms that focus on eradicating obesity.” (At p. 11) The footnote here states, “For instance, in 2008, the Obesity Society published a paper defining obesity as a disease. At the end of this paper, the authors acknowledged that “the Obesity Society and members of the writing group have accepted funds from multiple food, pharmaceutical, and other companies with interests in obesity. As investigators for the New York Times noted in 2009, however, many articles in medical journals do not even acknowledge their ghostwriters or financial ties. See Wilson and Singer, Ghostwriting is Called Rife”: Singer and Wilson,” Medical Editors Push for Ghostwriting Crackdown”

Comment: With the exception of a handful of obesity-deniers, I do not know of a single public health expert who does not agree on the physical risks of excess adipose tissue. That is not to say that there is agreement on all possible mechanisms or the conclusiveness of every study. No one familiar with the scientific literature would dispute that. It may be that the contribution of excess adipose tissue to inflammation or to insulin resistance in some groups may be more or less important than total body fat, fat distribution or Body Mass Index. Or that visceral adipose tissue is more important than total body fat.  Searching PubMed for “obesity health effects”, one finds over 18,000 medical articles. While some of these are no doubt inconclusive and some would show no relationship between obesity and a certain risk, others might reveal new risks, like the relationship of morbid obesity to H1N1 virus. But given the volume and wealth of data, the burden is on Farrell to come up with convincing evidence or at least something more impressive than quotation marks.

The issue of the health risks of obesity is different from describing obesity as a disease, however. That categorization as a disease has a number of implications and not all obesity researchers, pharmaceutical companies or other entities much less the public agree obesity should be considered a disease or that the Body Mass Index should define obesity or a particular BMI cutoff should be used. Believe me, I know. I am responsibility for getting most of those U.S. agencies referred to here to recognize obesity as a disease (see Bio),  Also, I have written on this topic and was the second author of the paper referred to in the footnote (and my stuff was not ghostwritten).

Farrell  again misses a good story. She might have observed that Oliver was looking at the activities in the U.S. agencies basically from 1997-2004,roughly my tenure as director of the American Obesity Association. But the Obesity Society paper did not come out for some 8 years later. There was not small concern within the leadership of the Obesity Society at the time that the Society would look a bit foolish coming to this position after so many other groups had done so. The reason is contained in the quoted disclosure statement of the paper which includes some authors receiving funding from food companies who had a lot of concerns about obesity being categorized as a disease.

Second, the designation of a disease did not do a lot to “legitimate” money spent on obesity research. The National Institutes of Health did see a large increase in the late 1990s but this had more to do with the scientific breakthroughs around the discovery of leptin which led to an explosion in the genetic understanding of obesity and, frankly, the lobbying  we did at AOA did for increases at NIH. In terms of treatment, the designation by the Social Security Administration, Internal Revenue Service and Medicare of obesity as a disease were helpful but did not make for sudden or dramatic change in coverage. For example, coverage of drugs for obesity treatment is still uncommon in public or private health insurance programs.

Third, the footnote’s reference to the Wilson and Singer 2009 article in the New York Times deserves some attention. The article had nothing to do with obesity at all. Contrary to the sinister implication of in her text, the Times issued a correction on September 12, 2009 which states, “Because of an editing error, an article on Friday about a study of ghostwritten research reports published in medical journals – reports with unacknowledged research or writing contributions by people other than the authors – misstated the role of drug companies in the reports that were examined. Although other studies have found that journal articles involving ghostwriters are often financed by drug companies, the study in question did not look for or find evidence of drug industry involvement in the ghostwritten articles.”

Now, I have written quite a bit, that obesity is a serious health problem, is an epidemic and should be referred to as a disease…because it meets any rational definition of “disease.” (These quotation marks are mine.) As a point of personal privilege, I have always disclosed any financial interest and the writing, whether at the American Obesity Association, the Obesity Society or this website has been mine. Farrell  ignores any of the facts behind such issues and just strings them along in an implication that everyone else is just on the take.

Farrell goes on to repeat a favorite story of the obesity-denier clan of the CDC having to walk back an estimate of 300,000 deaths a year due to obesity to a more modest figure of 112,000, implying you just can trust those folks.

But what is the evidence on obesity’s effect on health?

Well, it is pretty overwhelming. You can check my section, Health and Stigma, to see just how many health conditions are associated with obesity.  Causation is more elusive. Those connections are  the subject of active research.

First, it is pretty clear that there is a linear relationship of BMI to biomarkers for major diseases, such as C-reactive protein (for inflammation) HbAic (for diabetes) and high density lioporotein cholesterol (for cardiovascular disease).  According to this study, “in all age and sex groups, a higher BMI was associated with a worse biologic risk profile.” Overweight adults may have the lowest mortality–d… [Am J Epidemiol. 2011] – PubMed result .

Many specific connections to obesity-related diseases are very well established, such as:

Overall,  the scientific and medical concerns about obesity have been driven, in my experience, more by the morbidity and disability concerns than by the mortality figures. Controlling obesity is probably more important for controlling for disabilities than for mortality (See Life Expectancy and Life Expectancy With Disabilit… [Obesity (Silver Spring). 2011] – PubMed result and  Mortality and disability: the effect of overweight… [Int J Obes (Lond). 2009] – PubMed result ) In a sample of Medicare beneficiaries, obesity over BMI 35 did affect mortality and, at BMI 30 and more, impacted  functional decline Obesity, race, and risk for death or functional de… [Ann Intern Med. 2011] – PubMed result  This is why one of the very first fights I launched at American Obesity Association was against the Social Security Administration  to keep severe obesity as a condition qualifying for medical disability.

But that is not to say that mortality is unimportant.  A 2009 study of over 20,000 Dutch men and women between 20 and 65 found , in obese respondents,  a four-fold higher risk of a fatal cardiovascular disease (CVD) whereas the risk of a nonfatal CVD was two-fold higher than in normal weight respondents. In persons with a BMI over 25, half of all fatal CVD and a quarter of nonfatal CVD were attributed to their overweight. On the population level, one-third of all fatal CVD cases could be attributed to overweight and obesity and about one in seven of nonfatal CVD cases.

There are two reasons why some studies of mortality and obesity are inconsistent. The inclusion of smoking and pre-existing disease is one such confounder. The other is grouping the entire range of BMIs in three categories, normal, overweight and obese.

The Prospective Studies Consortium looked at the relationship of BMI to mortality in 57 prospective studies with 894,576 participants in western Europe and North America.  They excluded smokers and those with pre-existing cancer. They found mortality was lowest in the BMI 22.5-25 range. Above that range, they found progressive excess mortality due to vascular disease,and obesity was  probably causal. At a BMI from 30-35, median survival is reduced by 2-4 years; at a BMI of 40-45, it is reduced by 8-10 years, comparable to the effects of smoking.

#4 The colossal  health and diet Industry

Farrell  argues that the attention to the “obesity epidemic,”  “fuels a dangerous and profitable diet industry as well as the growing field of weigh loss surgery.”  And, “Just as Dwight D. Eisenhower in his 1961 Farwell Address called on Americans to be wary of the military-industrial complex, we need, I argue, to be just as wary of the diet-industrial complex…Our national “war on fat” has created  a colossal health and diet industry closely enmeshed with governmental agencies. Profit motives for our sixty billion diet industries and fat stigma have become so entangled that it has become difficult perhaps impossible, to even entertain the possibility that we are fighting the “wrong war”. In a profit-driven, consumer society, diet product manufacturers, pharmaceutical companies, the advertising industry, and medical practitioners all benefit financially from fat stigma. Through their lobbying efforts, these entities influence our governmental offices and agencies and public health campaigns; many in the corporate and medical world also serve as consultants or members of government offices and agencies. Yet, just as the purpose of the military-industrial complex is to maintain itself, not to seek peace, the purpose of the diet-industrial complex is to keep people dieting (or choosing surgery, diet pills, or membership in clubs) rather than to seek health. ” (p.12-14)  

Comments:  All good conspiracy theories need a sinister, behind the scenes  and here we have it – the “weight loss industry. But let’s take a look at some of these claims more analytically.

#1 “Colossal”

The  figure Farrell quotes elsewhere (p.176, for example) on the size of this colossal industry is $60 billion a year, a figure which I believe comes from MarketData, a firm that specializes in economic research on the weight loss industry.  But what is included in that figure?  The categories include diet books, exercise videos,  commercial chains (Weight Watchers, LA Weight Loss, eDiets,  Medifast), diet soft drinks and artificial sweeteners, low-calorie foods (e.g. Healthy Choice, Weight Watchers, Lean Cuisine, Atkins), meal replacements (e.g SlimFast), appetite suppressants (e.g. Herbalife) , medical weight loss  and hospital based programs(e.g. Lindora Medical Clinics, Medi-Weightloss Clinics, Health Management Group), bariatric surgery, diet drugs, fasting programs (e.g Optifast, Health Management Resources) registered dietitians and nutritionists, health clubs (e.g. Bally’s Curves, 24 Hour Fitness), diet food delivery market (Jenny Craig, NutriSystem) and weight loss websites.( Interestingly, dietary supplement business  for weight loss is not included). While the number $60 billion is a big number, I suspect that if one takes out diet sodas, artificial sweeteners, low-calorie foods and meal replacements, which are used by many consumers not necessarily those trying to lose weight or prevent weight gain, the number becomes much smaller.  For comparison purposes, $60 biiion is:

> about 1/3 the size of the fast food industry US Fast Food Industry to Cross US Dollar 170 Billion by 2010

>  1/12 the size of the  $497 billion US food and beverage industry  (give or take a little double-counting) food industry rankings | Top 100 for 2005: This chicken comes first | Food Processing magazine

> about the size of the US battery business Batteries set to become $60 billion industry by ’13 | Green Tech – CNET News.

#2  It is just like the military-industrial complex

What Eisenhower was alluding to was the close financial and personal ties among Congress , the Pentagon and defense contractors. The contractors lobby Congress for new weapon programs, Congress appropriates the money to the Defense Department who gives it to the contractors and personnel move seamlessly between Congress, the Pentagon and contractors. It’s been called the Iron Triangle.  Let me tell you, that is not the situation of the weight loss industry. The weight loss field is highly fragmented. The component sectors do not work together and often define themselves that they are different from the other components. They have no trade association and no source of funding like what Congress is to the defense industry.  When I was director of the American Obesity Association, we were one of the very few organizations that had funding from several sectors, such as commercial programs, the pharmaceutical companies and surgical companies. But it wasn’t easy. And, each sector has different agendas.  The commercial plans, dietary scam artists and dietary supplement folks are scared to death about prosecution by the Federal Trade Commission or the Food and Drug Administration for false or misleading advertising. The pharmaceutical and surgical companies have to go to the Food and Drug Administration for approval but at the same time are competing between and among each other for market share. After approval, they want to be the left alone.  They have mixed views on getting reimbursed in governmental programs. The physicians and medical programs get upset at the government’s often simplistic recommendations to just eat less and exercise more knowing that that is an inadequate solution for most people. When was the last time you heard the Surgeon General recommending bariatric surgery or diet drugs? It isn’t there.

Farrell’s model appears unsuited to accommodate non-for-profit charitable foundations which have become heavily invested in obesity, especially childhood obesity over the last ten years. The most prominent of these is the Robert Wood Johnson Foundation which is not even mentioned. It has committed millions to fighting childhood obesity. Childhood Obesity – RWJF Are they dupes of SlimFast?

Later in the book (p.176), Farrell predicts that the current economic downturn  will only lead desparate overweight persons to add fuel to  the diet industry. This does not seem to be the case according to reports in 2010. It’s The Year of The Value Diet – CNBC. Bariatric surgery rates are also down. Trends in Use of Bariatric Surgery, 2003-2008. [J Am Coll Surg. 2011] – PubMed result

#5  Stigmatization of fat people preceded health concerns

Farrell central thesis is that , “This idea  – that we think poorly of fat simply because we know it is unhealthy – is particularly powerful within our contemporary context when health warnings surrounding fatness are ubiquitous, nonstop and very alarming. What is clear from the historical documents, however, is that the connotations of fatness and of the fat person – lazy, gluttonous, greedy, immoral, uncontrolled, stupid, ugly, lacking in will power, primitive – preceded and then were intertwined with explicit concern about health issues.” (Emphasis added)  (at p.34)

Comment: Unfortunately, the historical record shows exactly the opposite. Health concerns about obesity can be traced to ancient Greeks and Egyptians. Hippocrates wrote about obesity leading to infertility, sleep disturbances, and death. Others, such as Polybus and Galen, also identified health risks associated with obesity. This attention continued through the 16th and 17th centuries. In the 18th Century, the connection between obesity and women’s health began to be made. Obesity: a medical history. [Obes Rev. 2007] – PubMed result

Indeed, the Greco-Roman and Byzantine worlds were quite interested in obesity and saw the best body type as one in which thinness and obesity were in balance. Interestingly, the Mediterranean diet can be traced back to this period. Greco-Roman and Byzantine views on obesity. [Obes Surg. 2007] – PubMed result

Unfortunately, I think Farrell  has missed a major, perhaps the major, cause of stigmatization in America. Its roots, however, are in Europe. This a fusion of Greek philosophy which idealized moderation in all things and the avoidance of extremes and Christianity, which made gluttony and sloth mortal sins (the most serious kind). Gluttony involved both the taking of too much pleasure in eating or drinking as well as overconsumption. The comparable virtues were temperance and diligence.  In the 19th Century, these sins/virtues would be well known to most American of European-Christian heritage.  The view  can be summarized succinctly as Personal Responsibility.

To this we can add a uniquely  American ingredient – unbridled self-confidence in overcoming our environment and our enemies. After all, we had defeated the world’s greatest military power, Britain – twice. We had survived the Civil War, expanded westward  across a continent, and created unparalled economic growth and opportunities.  We would free ourselves from slavery, build railroads, an interstate highway system, an automobile industry, world-class institutions of education, defeat other empires – Spain, Germany, Japan and Russia, explore space and put a man on the moon. We would defeat numerous diseases and unlock the genome. Through public health measures and medical treatments, we were actually able to extend the lifespan.  Is it a surprise that the first African-American man to beelected President of the United States would share his campaign slogan with that of the National Institutes of Health childhood obesity campaign, We Can?

Whenever issues of obesity have arisen, Personal Responsibility combines with We Can to produce a powerful attitude that if a person really wanted to avoid obesity they have the tools within themselves to do so. Societal intervention, be it in the schools or workplace or community, are not needed, except to repeat the “Personal Responsibility + We Can” mantra.

So stigma is seen, by many I believe, as a good thing because it serves to remind the individual that they are responsible for their health and can fix their problem if they only try hard enough. This is, I believe, a core belief about obesity and persons with obesity.

This view may have some support from a small, recent study which found that people’s views of an obese person as lazy or incompetent were mediated by how they lost weight.  When told the weight loss was due to diet and exercise responders had a more favorable view than when told the loss was due to surgery. Changes in weight bias following weight loss: the … [Int J Obes (Lond). 2011] – PubMed result

Of course, this still begs the question of when stigmatizing people because of their body size started. We may never know this. We do know that by the 16th Century, Shakespeare was making connections between body dimensions and character. In Julius Caesar, Caesar said of one of the conspirators, Cassius, “ Let me have men about me that are fat, Sleek-headed men and such as sleep a-nights. Yond Cassius has a lean and hungry look, He thinks too much; such men are dangerous.” (Julius Caesar, Act I, Scene 2, l. 190-195) Hostess Quickly of the Boar’s Head Tavern complains of the fat rogue, Sir John Falstaff,  who was depicted as gluttionous, lazy and disloyal, “He hath eaten me out of house and home, he hath put all my substance into that fat belly of his: but I will have some of it out again, or I will ride thee a-nights like the mare.” (Henry The Fourth, Part 2, Act 2, Scene 1, l.74-79)

#6   This industry leads people into futile and  dangerous  weight loss efforts.

Throughout the book, Farrell describes weight loss efforts as either dangerous (like bariatric surgery and yo-yo dieting) or futile or both. The futility of weight loss is a critical element of her narrative. For, if weight loss efforts are successful, then urging people to lose weight is justified. If no one can safely lose weight, it is dangerous and misleading to urge them to do so. She states without citation the old saw that 95% of dieters regain their weight.

Comments:  Farrell sweeps a wide range of interventions into one tent and says all are futile. The reality is far more complex than Farrell presents. The 95% figure has an interesting provenance which I thought everyone in the obesity world knew. It comes from one of the senior scientists in obesity, Dr. Albert Stunkard of the University of Pennsylvania. He described the 95% failure rate in 1959, over 50 years ago. As many people who know “Mickey” as his friends call him, he has regretted it ever since. What he was referring to was the simplistic approach in his clinic at the time of basically telling patients to go home and lose weight. See Book Exclusive: Is Sustained Weight Loss Possible? ;  95% Regain Lost Weight. Or Do They? – New York Times ; Diet and Myths Weight-Loss Lore and Controversies – Why Diets Fail – Term, Obesity, People, Maintenance, Treatment, and Regain  That strategy  wasn’t successful then and it still isn’t. Continual exhortations that this is easy are misleading and can be stigmatizing. But it is not the whole story.

What is failure What is success?

The first question is what is failure and what is success for a diet? This is not an easy question. Many dieters have unrealistic expectations about how much weight loss they can lose. See Weight loss expectations and goals in a population… [Obesity (Silver Spring). 2008] – PubMed result Many feel that losing weight once should be enough to keep it off forever. They are shocked, shocked that the weight loss is not permanent. Alas, it isn’t so.  If one does not take steps to maintain the weight loss, it will come back. But why should we presume that a weight loss should last one year or two or five years or more?

Can people lose weight and does it improve health?

Well, actually yes. In the Diabetes Prevention Program (DPP)  an intensive lifestyle intervention was compared to drug therapy (metformin) to examine a reduction in risk for development of Type 2 diabetes. At one year, intensive lifestyle participants lost 8.6% of initial weight loss compared to controls The lifestyle intervention significantly reduced the incidence of diabetes by 58% compared to 31% in the metformin group, as compared with placebo.  Reduction in the incidence of type 2 diabetes with… [N Engl J Med. 2002] – PubMed result   The 10 year results of the DPP showed significant reduction of type 2 diabetes in the lifestyle group.

Both groups lost a significant amount of weight at 12 months, about 26 lbs. Waist circumference, visceral abdominal fat, liver fat content, blood pressure and insulin were reduced in both groups. The addition of physical activity promoted greater reductions in waist circumference and liver fat content. Effects of diet and physical activity intervention… [JAMA. 2010] – PubMed result

Maintenance of Weight Loss

Maintaining weight loss is extremely difficult. There are powerful biological mechanisms which defend a body’s weight.  It has been known at least since 1995 that in obese patients, a 10% decrease in body weight requires a reduction of 15% or more in calorie intake predicted for the same body weight in a normal with person. Changes in energy expenditure resulting from alter… [N Engl J Med. 1995] – PubMed result

But is it the fault of the diet? I have an analogy. You have nice lawn but the grass has grown too high. You mow it. A couple of weeks later, the grass is high again. Is it your lawmower’s fault? Did the lawn care industry make you want to cut the grass? Or is it in the nature of grass to keep growing and need repeated cutting? Does the environment (warm, wet weather) affect the rate of growth? Now, few of us would blame the lawnmower, although blades might be dull. But, by and large, we understand that grass will continue to grow. So it is with weight loss, in my opinion. The diet achieved its loss but the biological properties combined with environmental influences keeps it growing, at least for a while. Weight loss is not a one time thing, unfortunately. A great deal of effort has to go into maintain a lower weight, in large part because of the bodies’s weight maintenance system.

Successful weight  mainteners it seems, engage is some specific activities to maintain the loss. These include a high level of physical activity, low fat diets and careful calorie counting.

Interventions specifically for maintenance may help. In one study, personal contact by a health professional seemed to have better effects on weight maintenance than leaving it just to the individual. Comparison of strategies for sustaining weight los… [JAMA. 2008] – PubMed result 71% of participants remained below their entry weight after 30 months.

The researchers found both groups lost approximately 123 lbs after one year with slight regain of about 4 lbs. in both groups. Weight-loss maintenance in successful weight loser… [Int J Obes (Lond). 2009] – PubMed result

Yo-Yo Dieting

One of the narratives of NAAFA which Farrell uncritically adopts is that repeated dieting is worse than being obese.  The facts do not support her. In a study of 44,882 middle-aged and older women in the Nurse’s Health Study, women who reported they had intentionally lost at least 20 lbs. at least 3 times were classified as severe weight cyclyers. Women who had intentionally lost at least about 10 lbs  at least 3 times but did not meet the criteria for severe weight cyclying were classified as mild weigh cylcers. The researchers looked at all-cause mortalilty and cardiovascular mortality. During 12 years of follow-up, 2,884 women died. Weight cyclers gained more weight than noncyclers but mild cyclers gained about as much as noncyclers. After adjusting for age, weight change, etc, there was no increase in all-cause mortality among mild or severe recyclers. Weight cycling and mortality among middle-aged or … [Arch Intern Med. 2009] – PubMed result The weight regain by severe cyclers may be due to higher levels of binge eating and low levels of physical activity.

Weight change, weight fluctuation, and mortality. [Arch Intern Med. 2002 Dec 9-23] – PubMed result

                Surgery

Farrell repeatedly and exclusively describes surgery in only the most negative terms and seems unaware of the significant advances in safety over the last ten years, principally due to the switch from open procedures to laproscopic procedures and the introduction of gastric banding and the move to high-volume centers of excellence.  The considerable body of evidence of the effectiveness  and safety of surgery in appropriate patients, particularly in centers of excellence is addressed elsewhere (See Managing Obesity). To Farrell, any such balanced statements are to be considered “propaganda.” (At p.169)

7         Fortunately, the Healthy-At-Every-Size movement will save the day

Farrell writes approvingly that there is an alternative to the traditional weight loss paradigm , Healthy-At-Every-Size (HAES) which she describes as moving from, “How doe we make fat people thin?” to “How do we make fat people healthy?”  HAES advocates, she says point, to studies that suggest fatness is not particularly malleable, and that restrictive dieting causes only short-term weight loss but results in long-term metabolic disturbances. These advocates, she says,  “argue with studies with headlines that tout the “dangers of obesity” (her quotation marks) usually demonstrate that a sedentary lifestyle and a diet of processed foods result in ill health; and  a diet rich in fruits and vegetables and an active lifestyle will improve health but it may or may not result in weight loss.” (At p. 11) Emphasis in original.

Comments:  First, the traditional weight loss paradigm is not “How do we make fat people thin.” Without doubt, there are a lot of diet products and services which advertise miracle weight loss and the attainment of an ideal body. We call them scams. (See Consumer Protection )They are a deplorable and often deceptive and misleading part of the weight loss world. But they are only a part. Some medical practitioners and surgeons have used  dramatic before-and-after pictures of their most successful patients. But by and large, those practitioners are becoming fewer and fewer, being replaced with younger, more data-driven practitioners.  Enforcement actions of consumer protections laws by the Federal Trade Commission and the Food and Drug Administration have helped drive many of the worst  out of business. Despite these efforts,  they are still around. Their heavy advertising is deeply unfortunate, creating in the minds of many that weight loss is easily attainable without effort.  But most programs today want their patients or customers to have realistic expectations. The medical community and other advocates, such as the STOP Obesity Alliance, have for years urged  a focus on a 5-10% weight loss not for cosmetic purposes but to achieve clinically meaningful health results. Policy Recommendations – STOP Obesity Alliance (Disclosure: I am Policy Advisor to the STOP Obesity Alliance)

Second, we’ve discussed the short term v. long term weight loss above. However, her claim that diets cause “severe long-term metabolic disturbances” requires some explanation on her part.  I think I am familiar with the obesity literature and I have never seen this claim that restrictive dieting causes serious long-term metabolic disturbances. If Professor Farrell has such documentation, she should cite them. (I am assuming this reference does not include gallbladder disease and reduced bone density which could be easily mentioned and are controlled as opposed to the more ominous “serious long-term metabolic disturbances.”)

Third, it may be understandable that Farrell adopts the assumption (driven by stigma in my opinion) that persons with obesity eat a diet high in processed foods and low in fruits and vegetables.  There never was, to my knowledge, any evidence of this. But it is a widely-held assumption. Well,  It isn’t true. According to a recent study, published in 2011, found that energy intake (read calories) increased across all BMI categories – normal weight, overweight and obese groups in 2005-2006 compared to 1971-75. The increases in consumption of carbohydrates (from 44% to 48.7%) and, the decrease in fat consumption  (from 36.6% to 33.7%) and of protein (from 16.5% to 15.7%. Therefore, there is no difference in the foods consumed by persons with obesity and the rest of the US poulation. Trends in carbohydrate, fat, and protein intakes a… [Am J Clin Nutr. 2011] – PubMed result

And what traditional weight loss program does not recommend increased consumption of fruits and vegetables and increased activity? Aren’t these the ones she just said are futile?

So what makes HAES so valuable. HAES espouses three principles, First, don’t try to lose weight. Losing weight is worse health-wise than being obese or overweight. Second, accept your body and don’t try for an idealized body. Third, be active. Fourth, eat intuitively, follow your bodies natural cues as to what and how much to eat. Put the pleasure back in eating. Health at Every Size

Well, there just isn’t any evidence that losing weight is riskier than being obese. No problem with people accepting their bodies and having realistic expectations or being active. However, a good case can be made that we are in the problem we are in regarding overweight and obesity exactly because we have continued to eat intuitively in an unique environment where food is cheap, abundant and safe. Our natural cues have broken down in this environment.

Nevertheless, HAES advocates believe their programs can make persons with obesity healthy without losing weight. HAES’s studies have been around for over a decade and the results have never been impressive. Subjects don’t lose much weight on the HAES program and don’t seem to improve other health parameters. In the most recently published randomized clinical trial, 144 women were randomized to either the HAES group, a support group and a control group. After a year, about 2/3 of the women in the HAES group had a slightly lower body weight at one year. (The mean BMI in this group changed from 30.1 to 29.5 so there was not much change.) But were the subjects healthier, as promised by the HAES advocates. Well, no. The researchers states, “No significant groups by time interaction was observed for anthropometric measures (ie, BMI, and waist and hip circumferences), metabolic parameters (ie, low-density lipoprotein, cholesterol, high-density lipoprotein cholesterol, triglycerides, systolic blood pressure, and diastrolic blood press) and level of physical activity.” Health-At-Every-Size and eating behaviors: 1-year … [J Am Diet Assoc. 2009] – PubMed result

So what to make of HAES? It’s basic premises are simply unsupported by the evidence. It seems less an alternative to medical weight loss programs than perhaps a way to support the much smaller population which is both obese and have disordered eating behaviors. HAES not having much impact. More obese Americans than ever are trying to lose weight by consuming fewer calories, physical activity or both Temporal changes in trying to lose weight and reco… [Prev Med. 2009 Aug-Sep] – PubMed result

The rest and bulk of the book seems like a stream of consciousness exercise stringing along 19th Century postcards and cartoons, Monica Lewinsky, Oprah Winfrey, Brittany Spears, Barack  and Michelle Obama,  Bill and Hillary Clinton, Al Roker and Kirby Puckett. It is reads like a People magazine of fat stigma.

Fat stigma is a powerful force which has impeded research and treatment of obesity, not to mention justifying terrible treatment of thousands if not millions of individuals. It deserves better exploration than this book provides. Fat shame.

These are exciting times for health care reformers. We seem to have a President who is truly committed to reform of the health care system with the political strength to get his program enacted, at least a good part of it. What is the President’s program and how does or can, obesity be part of it?

First, some parts have already been enacted in the American Recovery and Reinvestment Act (ARRA), aka the Stimulus Bill. Millions of federal dollars are starting to flow into (a) expanded Health Care Information Technology, (b) comparative-effectiveness research and (c) expanded research at the National Institutes of Health. In addition, President Obama and several of his key aides, such as Melody Barnes, Director of Domestic Policy Council, and Peter Orszag, director of Office of Management and Budget have both addressed obesity and its important role in reducing health care costs and increasing the nation’s health.

Second, a major component to be worked on this summer is providing health insurance to millions of Americans without health insurance.

How might these plans affect obesity?

Healthcare Information Technology (HIT) may provide some interesting opportunities. In a few places, extensive clinical databases are already in use which track patients receiving bariatric surgery. The Surgical Review Corporation, for one, has 100,000 surgical patients which are being tracked for long-term outcomes. The Geisinger Medical Center in central Pennsylvania also has extensive database on patients in surgical and medical treatment. Such clinical registries can provide a vast improvement in understanding obesity and its co-morbidities as well as tracking long-term improvements. Doing this in real time with real-world patients can add tremendous information to clinical trials, which, by their nature, have more restrictive populations and end-points. Last year, the National Committee on Quality Assurance (NCQA) expanded the widely used HEDIS system which measures quality in managed care plans to capture Body Mass Index (BMI) for adults and children. The Administration’s emphasis on electronic medical records (EMR) in primary care practice, by requiring capture of BMIs, along with other clinical indicators, such as blood pressure, cholesterol levels and lipids, can provide a tremendous database for researchers and has the potential to greatly improve patient care. But there is a third level as well. Private entities, such as Google and Microsoft, are developing Personal Health Records (PHR) for individuals to track their own information, which might include nutritional and exercise patterns. One can almost envision a system whereby food and exercise diaries, clinical indicators, pharmaceutical and surgical information is available for patients, health care professionals and researchers.

Of course, such systems take a lot of effort. Common terminology must be agreed to. Data has to be able to be verified. Systems have to interface and patient privacy has to be protected. Who owns this information is a critical issue.

Comparative effectiveness research has already received a great deal of funding under ARRA. The Institute of Medicine has a panel recommending research priorities and, given the discussion at a public meeting on March 20, 2009, there is good reason to anticipate that obesity will be one of the priorities. But the question should not be just what is the best way to lose weight. The research should look at weight loss by various interventions against standard treatments for a number of the co-morbid conditions associated with obesity. And, while there is good data on the efficacy of weight loss for resolution of type 2 diabetes and cardiovascular disease, less is know about its efficacy in mobility problems, such as knee and hip replacements, asthma or breast cancer.

Finally, the Obama Administration has an enormous opportunity in the coverage of the uninsured to make a real change for persons with obesity. First, the Administration should oppose using overweight or obesity as a pre-existing exclusion. While we do not know what percent of the uninsured population is overweight or obese, it is unlikely that the rate is any lower than the national averages. To exclude 30-60% of the uninsured population because of their weight would be poor policy indeed. Next, the Administration should provide a full range of interventions from counseling on nutrition and physical activity to pharmaceutical and surgical interventions. Not only would this directly address the source of many of the uninsured population’s health care problems, it could break the logjam of resistance to coverage of obesity prevention and treatment. While these two steps will be costly, we have seen the rising rates of health care costs and obesity go hand-in-hand. Economists today see obesity as a major contributor to chronic illness and its costs. Finally, coverage should be tied into electronic records which can track long term outcomes.

In the April 15, 2009 issue of the Journal of the American Medical Association, Johathan Q. Purnell and David R. Flum estimate that gastric bypass surgery could save 14, 310 diabetes-related deaths over five years. The evidence on the power of weight loss to prevent and improve chronic disease is there, if not yet perfect. The Administration has an opportunity to make a major leap forward in addressing obesity. It should not miss this chance.
