The Paleo Diet: Also known as the Caveman Diet, the Paleo Diet is where you’re supposed to eat like your ancestors. This means eating a lot of animal protein, nuts and natural carbohydrates (fruits and vegetables).
PROS: If you struggle with diets that start by being very restrictive, the Paleo Diet could work for you because it does the opposite. It begins with three ‘open’ / cheat meals a week, which decrease as you progress to different levels. Eliminating things like processed food will improve your health.
CONS: This diet lacks dairy products, which is how most of us get our daily dose of calcium and vitamin D. You may also find it hard to sustain, because it lacks variety and it is supposed to be a long-term plan.
