Thanks for the links. I'll check them out.
Because the body maintains homestasis. It's inherently true, anyway, since over and undereating are determined by necessary caloric requirements to maintain homeostasis. Fat people have to work to stay fat, since lipolytic hormone levels increase as fat and mass increase. A person who eats five large pizzas per day will lose weight by only eating four. It's a negative feedback loop.
Well, I would argue that if "eat less" and "move more" worked the way some people posting on this board seem to think, there is no way that millions of people would remain overweight or obese, given that they face such judgemental people on a daily basis. People may be lazy, but they're also vain as all get out. But for the sake of argument, I'll accept your premise that it's easy to lose weight - overweight people just need to eat less and move more. But why lose weight in the first place? At least one recent study (http://www.nature.com/oby/journal/v1...y2009191a.html) suggests that people with very low BMIs and people with very high BMIs have greater mortality risks, but that those in the "normal" range and those in the "obese" range actually have pretty similar risks, and those who are in the "overweight" category actually are at the lowest risk. It suggests that in reality, the run-of-the-mill obese and those of us who are in the "normal" range are about the same, healthwise (all other things being equal), but we're all worse off than those who are overweight. So for me the question is: why encourage people who are overweight or obese to become like those of us who fall into the normal range? Plus, losing weight and regaining it actually appears to make one's health worse than if a person had not lost the weight in the first place, so it seems kind of silly to encourage healthy people to focus on losing weight. (I'm refering to the Lissner et all study in the New England Journal of Medicine 1991, vol 324, pg 1839-1844). If you're overweight or obese but healthy, why risk losing and regaining the weight, thus increasing your risk for being unhealthy?
I said 'obese'.
See the study linked above. Another (earlier) one with similar results is the Waaler et al, "Height, Weight and Mortality" 1984 study. Neither of these are gospel, and future studes may prove them to be incorrect, but both for me call into question the idea that we can assume people who are overweight or even obese are unhealthy. Basically, my contribution to this thread is simply this: it's wrong to assume overweight, and even obese, people are unhealthy. And while this is a forum devoted to style, I think it'd be silly for a healthy man to put his health at risk by trying to lose weight so he can buy nice clothes.
