There is an alternative theory, one that has also been around for decades but that the establishment has largely ignored. This theory implicates specific foods—refined sugars and grains—because of their effect on the hormone insulin, which regulates fat accumulation. If this hormonal-defect hypothesis is true, not all calories are created equal, as the conventional wisdom holds. And if it is true, the problem is not only controlling our impulses, but also changing the entire American food economy and rewriting our beliefs about what constitutes a healthy diet.
When a construction worker, somebody who you could say exercises ALL DAY, becomes obese, then eliminating obesity is a little more than “eat less, exercise more.”
Every time I think of this I’m reminded of when people would talk about the French paradox: a culture of people who eat fatty foods and drink wine and don’t get fat. HOW COULD IT BE?!
