6. Paleo Diet
The Paleo diet is based on the idea that we should eat the way we did back in the Paleolithic era—caveman-esque. All cereal grains are banned, as are dairy products, processed foods, beans and potatoes. But if you’re a meat eater, then you’ll love this! The Paleo Program encourages you to eat your fill of meat, fish and eggs, accompanied by fresh fruit and vegetables. Best of all, there is absolutely no strict plan, just food monitoring and taking in the right foods.
