The facts of the matter are:
* The health risks associated with increasing weight are generally small, in comparison to those associated with, for example, being a man, or poor, or African American.
* These risks tend to disappear altogether when factors other than weight are taken into account. For instance, fat active people have half the mortality rate of thin sedentary people, and the same mortality rate as thin active people.
* There is no good evidence that significant long-term weight loss is beneficial to health, and a great deal of evidence that short-term weight loss followed by weight regain (the pattern followed by almost all dieters) is medically harmful. Indeed, frequent dieting is perhaps the single best predictor of future weight gain.
* Despite a century-long search for a ‘cure’ for ‘overweight’, we still have no idea how to make fat people thin. The war on fat has reached the point where systematic distortion of the evidence has become the norm, rather than the exception. The basic strategies employed by those who profit from this war are to treat the most extreme cases as typical, to ignore all contrary data, and to recommend ‘solutions’ that actually cause the problems they supposedly address.
