The Paleo Diet is a diet in which the food quality is of utmost concern and attempts to closely mimic the diets of our ancestors prior to the agricultural revolution.

What Should I Eat on the zone?

In plain language, base your diet on garden vegetables, especially greens, lean meats, nuts and seeds, little starch, and no sugar. That’s about as simple as we can get. Many have observed that keeping your grocery cart to the perimeter of the grocery store while avoiding the aisles is a great way to protect your health. Food is perishable. The stuff with long shelf life is all suspect. If you follow these simple guidelines you will benefit from nearly all that can be achieved through nutrition.



The Paleo diet mimics the foods that our ancestors ate prior to the agricultural revolution. The Paleo diet is sometimes referred to as the Caveman Diet or Stone Age Diet. The idea around eating in this manner is that our bodies adapted to eating vegetables, lean meats, fruits, nuts, seeds over a 2.5 million year period and only recently with the introduction of processed foods have we began to suffer from diseases of affluence (diabetes, coronary heart disease, obesity, etc). “As a rule biological organisms are healthiest when their life circumstances most closely approximate the conditions for which their genes were selected.”-S. Boy Eaton, M.D., and Staffan Lindeberg M.D
