I don't understand what you're saying: > people pushing the idea that diet / food restriction alone is sufficient for weight loss Diet/food restriction alone is strictly sufficient for weight loss: I'm pretty sure this is uncontroversially true, but it sounds like you're saying it isn't. Am I misunderstanding you?
