Ten Famous People on the Paleo Diet

Unlike complicated fad diets or tedious calorie counting regimes, the Paleo Diet, founded by Dr. Loren Cordain, brings things back to basics. Way back - all the way to the Paleolithic era. Translation? If a caveman did not eat it, then you should not either.

Tens of thousands of years ago, before Doritos and Lucky Charms, our Stone Age ancestors thrived on a rich diet of meat and fish, fruits and vegetables, and healthy fats from nuts and seeds, without the stimulating hormones Growth, antibiotics and toxins that were introduced into our food during the Agricultural Revolution. This nomadic hunter-gatherer lifestyle did not allow growing crops (or hauling a cow), resulting in a diet completely devoid of grains, dairy, sugar, alcohol or any other processed or refined food such as corn, white potatoes, and misery.

While experts do not seem to agree on whether Paleo's promise is a passing fad or a seriously intelligent lifestyle, let's let these 10 known people of the Stone Age help you decide.

Miley Cyrus

1. Miley Cyrus

Miley Cyrus has permanently given the bread a bad rap, nixing it entirely from her diet because of her gluten and lactose allergies.

"Everyone should try gluten-free for a week. The change in their skin, physical and mental health is amazing! It will not return!" Cyrus told US Weekly. Paleo's free grain policy makes this low-carbohydrate, non-dairy diet compatible with the gluten-free lifestyle of Cyrus.

Mathew McConaughey

Everyone in Hollywood knows (with lots of paparazzi photos to prove it) that Matthew McConaughey is not afraid to show his physique in public. Not wearing a shirt helps too. Dubbed one of the people magazine`s "Sexiest Men Alive,", the actor agrees to eat Paleo 90 percent of the time. When he`s eating, that is.

Kobe Bryant

The pursuit of that sixth championship ring requires this star of the Laker show to remain in top form. Although not a Paleo dieter strictly, Bryant focuses on eating only grass-fed products, limiting his intake of carbohydrates, and erasing sugar and processed foods from his diet. The result? "I feel like I can run all day," Bryant says. "A lot of that has to do with diet and be committed to that, and see what I eat."

The Paleo movement is spreading from Hollywood to the locker rooms as professional athletes catch on to the "Caveman" lifestyle. Green Bay Packers quarterback Aaron Rodgers told ESPN he brought his copy of The Paleo Diet on his road trip to Super Bowl XLV in Dallas. (Who won). Not too much the Paleo diet can do for a separate shoulder, though.

The beloved star of L.A. Clippers, Grant Hill, announced his retirement last year, making him the oldest player in the NBA. How did this seven-time NBA All-Star get in the best shape throughout his 19-year basketball career? It may have something to do with his strong belief in the Paleo lifestyle, which he believes is what allowed him to compete with the other "children" in court, even in his forties.

"I think I'm going to wear myself out mentally before I physically," Grant said in an interview with Paleo Lifestyle Magazine. "I know it sounds crazy because I've had a lot of injuries, but I feel at 40 now that I'm in better shape than when I was 32 or 33, and I know a lot of that has to do with eating."
