Say that the given diet of this individual is that of pur's. He keeps to it normally, 7 days a week, 1-2 cheatmeals a week, and works out 5 days a week. His workout schedule being [on/on/on/off on/on/off repeat] with cardio on off days. How would fasting for an entire day (off day) effect this individual? I don't even know where to start with this, but I don't think that the effects would be negligible... someone help me out here please.
