Yeah, the oversimplification sounds great, except it is a homeostatic mechanism, people extract and expend calories at different rates, and appetite responds differently to different foods. Energy in vs. energy out matters less if certain types of food aren't sating hunger effectively. First you say it "is that simple" then go on to say "except for..." and list exclusions. Whenever I feel unsympathetic, I imagine trying to "breath less" for several years.
