The 80/10/10 Diet by Doug Graham is backed by a lot of research in his book. He says fruit are what humans are meant to eat. Think of our early generations, thousands of years ago. Would they have looked at a wild hog and said “that looks delicious?” Would they have thought fields of grain look scrumptious? Probably not. But to reach out and grab a sweet, juicy orange or strawberry or blueberry - they look tempting and taste wonderful and are easy to gather (compared to wild animals).
Graham makes the case that fruit and vegetables provide everything the body requires. People who follow the program tend to lose a lot of weight and claim amazing amounts of energy. The title refers to what he claims is the ideal breakdown - 80% carbs, 10% fat and 10% protein. He says that most Raw eaters get way too much fat due to nuts and avocados.
As a guy who doesn’t like to cook or get involved with complex recipes, this seems like a perfect lifestyle diet. Now when I go to the store, I only shop in the produce aisle (as most health books recommend). I buy a lot of berries, apples, mangoes, bananas. Also a lot of greens. In the daytime, you only eat fruit or smoothies. At dinner, some more fruit and greens. What could be simpler?
