No less than The New York Times reports
The report on nearly three million people found that those whose B.M.I. ranked them as overweight had less risk of dying than people of normal weight. And while obese people had a greater mortality risk over all, those at the lowest obesity level (B.M.I. of 30 to 34.9) were not more likely to die than normal-weight people.
The report, although not the first to suggest this relationship between B.M.I. and mortality, is by far the largest and most carefully done, analyzing nearly 100 studies, experts said.
This might impact policy, if "nutrition" policy were about health, instead of about telling other people what to do.
