Some researchers contend that whatreally matters is the distribution of fat tissue on the body, with excess abdominal fat being mostdangerous; others say that cardiovascular fitness predicts mortality regardless of BMI or abdominal fat.“BMI is just a first step for anybody,” says Steven Stone, an obesity researcher. “If you can then addwaist circumference and blood tests and other risk factors, then you can get a more complete descriptionat the individual level.”If the obesity-paradox studies are correct, the issue then becomes how to convey their nuances. Alot of excess weight, in the form of obesity, is clearly bad for health, and most young people are better offkeeping trim. But that may change as they age and develop illnesses.Some public-health experts fear, however, that people could take that message as a generalendorsement of weight gain. Willett says that he is also concerned that obesity-paradox studies couldundermine people’s trust in science. “You hear it so often, people say: ‘I read something one month andthen a couple of months later I hear the opposite. Scientists just can’t get it right.’” he says. “We seethat time and time again being exploited, by the soda industry, in the case of obesity, or by the oilindustry, in the case of global warming.”Preventing weight gain in the first place should be the primary public-health goal, Willett says. “It’svery challenging to lose weight once you’re obese. That’s the most serious consequence of sayingthere’s no problem with being overweight. We want to have people motivated not to get there in thefirst place.”
