drink nothing but isopure?

My father, years ago, wouuld go on a 30 day fast, and eat nothing but pre digested protein (liquid) and a pre natal vitamin. Typically, he would lose 30+ pounds during that time. However, he wasn't a weight lifter, so this diet is not advisable.

I think u would be shutting down one important phase of your diet, which is digestion, the metabolism increases when u digest solid whole food making the muscle of your stomach work a little harder to process the food besides giving you the feeling of being full, I don't think ther's much short cut when it comes to dieting.
