I don't think anyone denies there is a huge part of dieting that is changing habits, lifelong habits. But most of them are just methods of consuming fewer calories. Most people would have an easier time losing weight if they just stopped eating before being full. Being full should be a luxury, not a daily occurrence. All the studies about "obesity genes" are more focused around the appetite, not anything about metabolism. Appetite is a feeling, sometimes in life your feelings are not always the best method to drive your actions.
