Now it's time for the morning stir. Something new than we're doing. We're going to dig deeper into what's buzzing, what's trending. The Paleo lifestyle. Not diet, lifestyle. Eating like our ancestors did. Sara Haines as the story. Reporter: The Paleo diet is hugely popular. But now, devotees are taking it to a new extreme. Adhering to the lifestyle. The modern day cave man movement. It mimics how they ate, moved, slept. There's the diet. And then a lifestyle. Exactly. Reporter: And you do all of the above? Yes, we're in. Reporter: They started living Paleo three yores ago. They own a Paleo chocolate company. You're at the desk and standing. We get the health benefits of standing. We're getting the work done. Reporter: The hunters and gatherers of the past would walk and hunt. They enjoy a morning walk through the wood are some interesting foot war. We wear these five-finger shoes. It mimics the natural movement of walking barefoot. Reporter: Later, afternoon Frisbee. Nice catch! Reporter: And lunch. What would a salad be without bacon? Reporter: This is delicious. What about sleep? Our ancestors' sleep pattern were done by sunrise and sunset. They wear blue blockers. It helps us get a more restful night's sleep. Reporter: They say their lives have not been better. Nick lost 12 pounds. Christine says she hasn't been sick since 2012. This is probably the longest fad in the history of mankind. It's been going on for 2.5 million years. My genes want me to be strong, lean, fit, happy, productive. Reporter: For "Good morning America," hasara Haines, ABC news, New York. Joining us now, Dave zinczenko. Let's start with the pros and cons. The diet and the lifestyle. On the diet side, it's great. It's telling you to cut out all processed foods. Americans, 70% of their diet is processed foods. That can't be a bad thing to eat less processed foods. On the lifestyle thing, they're saying exercise more and sleep more. That's awesome. If you can do that, it's great. It's hard for people to incorpora incorporate. Yes. What are the drawbacks? Any time you restrict certain foods or food groups, there will be drawbacks. Most Americans don't get enough vitamin B, D. If you cut out dairy, it's big. The list of foods you can't eat is huge. You may as well go to the supermarket and press your nose to the glass from the outside. This is tough to stay on. To sustain? It's hard to sustain because of -- it's deprivation. You're restricting the food groups. The best thing you can do is you have the community aspect to it. That's works. NER everybody in the pool. The diet is safe. The lifestyle is safe. Don't dive into the workout too much. It is sustainable if you find yourself with a community. People are saying, I'm living in 20124 A.D. You want me to live like it's 2000 B.C. A lot of people will struggle. Learn to cheat a little bit. What do you mean? Adopt an 85% rule. Allow yourself to drift 15% of the time. On weekends when you want to get crazy with friends, that's okay. Work in any kind of exercise that you can. It was Frisbee and walking in the woods on the taped piece. You don't have to do something crazy, like jump into exercise whole hog. Get the support of family, friends, loved ones. That's the community. If you have underlying health issues, talk to your doctor before starting any kind of new program. Thank you, Dave. We want to know what you think. Could you go Paleo?
