Re: Sorry for getting all unfunnybusiness...
Only people in the "underweight" and "obesity II" category have an increased risk of mortality compared to "normal" on the BMI chart. "Overweight" people have a decreased risk of mortality. There have been many long-term studies on this. Here are two.

Exercise has been shown to be highly beneficial regardless of weight loss, but weight loss has not been shown to be beneficial without exercise. Of course, it is impossible to test the benefits of weight loss in the long term, because statistically speaking people can not lose weight in the long term through any known method. (Except being seriously ill.) Most (but not all) people who don't exercise tend to gain weight. Therefore there is a correlation between high weight and unfitness, but it is not a causation. Many fat people are far more fit than many thin people.
