I’ve been sharing with you my thoughts on food and diet fads and cults—and today I’m tackling Weight Watchers. “What!!” you say? “Weight Watchers is an American institution!” Sure. Millions have lost weight with Weight Watchers. And I acknowledge the good things about it. But it’s a bit of a revolving door. Let me explain. If you’re going to lose weight, why not do it adhering to principles that will get you much healthier, and lower your disease risk. Would that be better than just calorie-suppressing, which, since the advent of Weight Watchers, has been proven time and time again to be ineffective over the long term?
