Want to start paleo diet(caveman diet). how do i prep myself?

Research it first. : Paleolithic lifestyle reflects life of paleolithic (stone age) forager- hunters. Diet incorporates meats, fish, fruits, nuts ; vegetables w attempts to avoid junk foods ; grains. Frequent, varied exercise, use of complex natural body movements, exposure to sun, time w nature, simplifying life, adequate sleep, stress-free periods ; close social groups for are just some aspects of a paleo life.

Mark's Daily Apple: There are a lot of great sites on this topic but Mark's Daily Apple has some great articles and the recipes are really great as well. If you want a book recommendation I would recommend Gary Taubes "Why We Get Fat" first for a great foundation. Other great reads would be Grain Brain, Wheat Belly, Primal Blueprint, Deep Nutrition. Also watch Dr. Robert Lustig's Sugar: The Bitter Truth on youtube.
