It’s weird that we’re still fighting about the root of obesity. In two decades of journalism, I’ve talked with a wide swath of the public health community, and one obesity-related issue — and possibly only one — unites them. When you peel back the objections to fat, or carbs, or processed foods, you get to the real problem: The food environment changed.
Just this month,in a paper about obesity as a risk factor for severe novel coronavirus infection published in the BMJ, the authors say: “The obesity pandemic is the result of living in food environments where it is difficult not to overconsume calories.” Full stop. It is not controversial.
