The Promise

Eat like a caveman and shed pounds. That's the theory behind the Paleo Diet.

Loren Cordain, PhD, who literally wrote the book on The Paleo Diet, claims that by eating like our prehistoric ancestors, we’ll be leaner and less likely to get diabetes, heart disease, cancer, and other health problems.

Also called the Caveman Diet or the Stone Age diet, it’s basically a high-protein, high-fiber eating plan that promises you can lose weight without cutting calories.

What You Can Eat and What You Can't

Go Paleo, and you'll eat a lot of fresh lean meats and fish, fruits, and vegetables, and healthier fats.

You can also eat:

You can't eat any processed foods on this diet. And since our ancestors were hunter-gatherers, not farmers, say goodbye to wheat and dairy, along with other grains and legumes (such as peanuts and beans). Other foods to avoid:

  • Dairy
  • Refined sugar
  • Potatoes
  • Salt
  • Refined vegetable oils, such as canola

Level of Effort: Moderate

There’s no calorie counting, and the fiber-rich fruits and vegetables will fill you up, as will the lean meat.

Limitations: The Paleo Diet allows for some cheating, especially at first. When you're just starting, you can eat what you want for 3 meals a week. Cordain calls those "open meals." Or you can challenge yourself to just one "open meal" per week.

Shopping and cooking: You'll need to stock up on the allowed foods and cook from scratch, so plan for kitchen time.

Packaged foods or meals? None. Processed foods are a no-no.

In-person meetings? None.

Exercise: Not required when you're losing weight. But Cordain strongly recommends it to maintain weight loss and for overall health.

Does It Allow for Dietary Restrictions or Preferences?

Vegetarian or vegan: This diet emphasizes meat and fish, and Cordain says it's impossible to follow a Paleo Diet without eating meat, seafood, or eggs. Excellent vegetarian sources of protein, such as beans and other legumes, are not allowed.

Low-salt diet: The diet doesn't allow salt, so it may help you cut down on sodium. If you do eat any foods that come from a can or a box, you would still need to check the sodium on food labels.
