I don't believe this myself, but I do know a lot of people who believe being overweight is unfairly demonized and not as harmful as TPTB would have us believe. Many point to BMI as an inaccurate gauge of healthiness (there's a fair point there about eating disorders and ethnic predispositions towards higher BMIs) and unhealthy obsessions with thinness (as opposed to fitness). Look up "Fat Acceptance" if you'd like to know more.
Personally, I don't think we should view fatness as a moral failing; some people do naturally tend towards higher weights, especially as they get older. But I also feel that fatness is really dangerous and unhealthy and the "Fat Acceptance" movement makes me a bit uncomfortable because, much like smoking cigarettes, some people need a bit of a push to kick bad habits like overeating. Obesity is very expensive, both in money and lives, so if we can reduce it, we should.
