Michael, a 25-year-old law clerk from Austin, Texas, lost over a third of his body weight, gained lean muscle mass and revitalized his health when he ate like a caveman.

Michael's Story:

"I lost 120 pounds eating a diet similar to the Caveman Diet. I weighed 285 pounds and now weigh 165 pounds. Recently, I've been following the Caveman Diet more strictly and have lost eight more pounds.

I've been gaining more and more muscle mass. My energy level is much higher. I rest better when I sleep and don't wake up feeling as tired. I'm more mentally alert.

The Caveman Diet has been a big help. I've already been on the diet for a number of years and now I'm following it more strictly. For dinner, I eat fish or grilled chicken with vegetables and nuts or fruit, along with a glass of freshly-made green tea or natural fruit juice.

Some of my friends who are my age are starting to have physical problems--lower back problems, arthritis and joint problems. Having better eating and physical habits can help them to lead longer, healthier lives.

The Caveman Diet is definitely helping people get in better shape and get healthier."
