Fad diets are a dime a dozen.
All claim to be the diet of the future, but what about the diet of the prehistoric past?
"I have grass-fed beef in the bottom and onions, carrots, and tomatoes. And I'll probably pour a broth in there, like a beef broth, or something later."
Kat Kadrmas has been dining like -- a cave women -- for two years and she says she's never felt better.
"Once I started this and I was seeing results and I felt good and I realized what was happening, I stuck with it and I've loved it ever since," says Kadrmas.
She started what's often referred to as the "Caveman Diet" -- after other diets failed.
Cavemen ate meat... and lots of it. They also ate fruits, vegetables, and nuts.
What they didn't eat-- grains and processed foods.
"You just have to keep in mind that it's meat and veggies. It's pretty easy to do that,"
says Kadrmas.
Dr. Steve Nagel has been living the caveman diet, also known as the Paleo lifestyle, for six years.
He says the health benefits reach far beyond weight management.
"Virtually all chronic disease has three major components: inflammation, insulin-resistance, as well as decreased immune system function. And so, when we look at the paleo diet, the combinations of foods are very anti-inflammatory, which slows down the disease process drastically. And it slows down the aging process. A side effect is increased energy, all that sort of thing. As well as, when it comes to insulin-resistance, we all know that diabetes is something horrible to have to deal with, but we also know that Type-2 diabetes is 100% preventable," says Nagel
Dr. Nagel says many people follow the paleo diet after being diagnosed with celiac disease or gluten intolerance.
But many also believe the diet can help with all sorts of issues.
Anything from asthma, to depression.
"We live in a sick society and the only way to really change that is to start to reintroduce health to the body. And this approach makes perfect sense," says Nagel.
"I think the biggest challenge is people don't understand or they think you are on some diet or that's stupid. There are always going to be people like that. You just have to let it roll off your back and say, 'That's how I eat!'" says Kadrmas.
Because both Kadrmas and Nagel believe looking into the past creates a more healthy future.
