So much truth here.
In the context of this discussion, however, let me just point out that the body is hard to manipulate by giving or withholding calories, since it can respond to quite a range of inputs. More relevant to the discussion is the whole basis of the ketogenic diet: what foods we eat are even more important than how much food we eat. I weigh ten pounds less today than I weighed yesterday, and not because I’ve been eating less, lately—if anything, it’s been the opposite, to tell the truth. Who knew that eating more could lead to my weighing less?
