The paleo diet [6565]

According to author Loren Cordain, modern health and diet problems didn't start with the advent of packaged snack food, but much earlier--back at the dawn of the agricultural age many thousands of years ago. As humans became less nomadic and more dependent on high-carbohydrate diets, we left behind the diet we had evolved with, which is based on low-fat proteins and plenty of fruits and vegetables. Sugars, fats, and carbs were rare, if they were present at all, and survival required a steady, if low-key, level of activity.
Cordain's book The Paleo Diet blends medical research with a healthy sprinkle of individual anecdotes, practical tips, and recipes designed to make his suggestions into a sustainable lifestyle, rather than a simple month-long diet; he even includes cooking recommendations and nationwide sources for wild game.
