The New Math of Obesity

The New York Times Science Section May 15, 2012 carries an interesting interview with NIDDK mathematician Carson C. Chow on the mathematical model he and colleagues developed. They found that the convention wisdom of 3,500 calories less intake is needed to lose a pound is wrong. Chow states, “The body changes as you lose. Interestingly, we also found that the fatter you get, the easier it is to gain weight. An extra 10 calories a day puts more weight on an obese person than on a thinner one. Also, there’s a time constraint that’s an important factor in weight loss. It actually takes about three years for a dieter to reach their “new” steady state. Our model predicts that if you eat 100 calories fewer a day, in three years you will lose, on average, 10 pounds – if you don’t cheat.”
