What Is the Paleo Diet?

Success Rate
The paleo diet is still pretty new, so there's not much research on the long-term success rates. However, one small study on nine individuals who consumed the paleo diet for 10 days showed that the dieters experienced better insulin response, glucose levels and lipid profiles after the trial period.

Health Pros and Cons
Pros are that it includes an abundance of produce and omega-3 fats, both of which are thought to benefit many areas of wellness. High protein intake may also mean that dieters will be less hungry on this plan compared to others.

The cons of the paleo diet, according to experts, are that it cuts out traditionally healthy foods like low-fat dairy, legumes and whole grains. These are thought to provide much of the calcium, vitamin D, fiber and other nutrients in many American diets.

How Easy Is It?
Some paleo plans are more restrictive than others, so it depends on the one you choose, as well as your natural proclivity toward certain foods. Some experts say it's fine to eat raw honey or coconut palm sugar in moderation. Others might instruct dieters to fast, consume only raw foods or eliminate nightshade vegetables like eggplant and tomatoes. One benefit to the diet's popularity is that there are plenty of recipes out there that make it easier for people to follow the plan.

Who Is It Best For?
Active individuals looking to gain muscle and lose fat may stand to benefit the most from this diet. In general, it's not recommended for vegans or vegetarians because it's so heavy in meat and restricts plant sources of protein like legumes and whole grains.

Costs and Special Products
Considering the relatively high costs of fresh produce and healthy meats, this diet may require some budgeting. But, there are no special products to buy.
