There must be some reason our ancestors lived a healthier and longer life than us. It just cannot be a chance that despite living in jungles, they lived a sturdy life and never caught any diseases. The reason is their diet- yes, the Paleo diet or the Stone Age diet. Obviously, there were no modern equipment in those days to process the foods, and they ate it in the purest forms possible. The idea of modern Paleo diet is also the same- to provide you with foods that can be eaten in their purest form possible. The unprocessed foods are the healthiest to eat, especially when you know that most of the foods we come across in the supermarkets are highly adulterated or processed.
Paleo encourages you to eat meats, fruits, and vegetables which are meant to be eaten for great health and a lean body. If you can sustain Paleo diet for a long time, you will thank yourself for taking a great decision.
