“Dr. Bacon responds: The evidence demonstrates that fat isn’t the bogeyman it’s made out to be, and that a focus on health habits, rather than weight, accomplishes the very goals collective thinness is supposed to achieve — if it were possible in the first place. And moreover, that social determinants of health — like racism and poverty — play a much, much bigger role in health than health behaviors. Attention to social change will be much more effective at health improvement than lecturing people to get more exercise.”
