@ktemkin Because it just does not work that way - people just fool themselves that it's a magic metabolism thing. If you properly count calories, you quickly realise that you'll never get there by exercising more alone (unless you exercise A LOT). Calories restriction is the only thing which really works. On the other hand, getting to positive terms with one's own body is another healthy thing. Weight loss/management is not an easy project for anybody. Take care and good luck there!
