The Caveman Diet
There is the bible diet of course, so why not the caveman diet. After all, in those times they were obviously skinnier than us, or maybe they just didn’t measure common rates of obesity as we do. But past history that we have recorded shows that people before us were never as obese as we are. That being said, the caveman diet is an original one to say the least. They focus on raw food.
Obviously many cavemen did not have fire, so there was a lot of uncooked foods. Obviously, don’t eat uncooked meat, that’s not exactly safe. But you get the idea. Second, apparently you should not eat dairy products, because there were no domesticated animals. Second, if you go for sweets, you should only be eating wild honey, not sugars, artificial flavorings, etc.
Finally, cavemen diets were apparently rich in good fatty acids because while they ate raw meat, which you shouldn’t do, most of what they ate came from nuts and other things rich in good fats to some degree. It’s a novel idea, and it’s written up in Dr Mark Hyman’s book Ultra Metabolism and Ultra Prevention. But I’m not sure it’s really practical all things considered.
