I've read up on nearly all the LC diets now, and there seems to be a consensus that the body must eitehr use glucose or ketones as the primary source of energy. However, I also have read that if you consume more protein that your body can use for tissue repair and other vital functions, it must be broken down to glucose and used as energy. This could produce an insulin response. While PP may not be extremely high fat, it does seem to be moderate fat. If the fat is not being used for energy (ketone production) then it would seem that the body would be forced to store it as fat (NOOOOO!). This seems to be an inconsistency that is incompatible with very basic LC principles.

Am I misunderstanding something here or is this a valid concern? From what I've read of people's journals, I would think that most people on the PP diet are consuming more protein than their basic functions require. Only people who train with weights need even close to 1 gm per lb of bodyweight (or even more).
