1. The 5-Factor Diet
WHAT IT IS:
Created by celebrity trainer and fitness guru Harley Pasternak, the “five” in the 5 Factor Diet
comes from the number of elements each meal should include – protein, complex carbs, fiber, fat and fluids. Followers eat five meals a day with recipes that contain no more than five ingredients. One cheat day is allowed per week where you can eat anything – and everything – you like, guilt free.
