You're a complete idiot. the keto diet has been the main diet of humans since the dawn of time. Only within the last 100 years has human kind switched from fat being the main source of calories to carbs. go take a look at the rising obesity rates and the rising diabetic rates in the last 100 years, it's directly tied to the fact that the human body was designed to run off fat and not carbs.

Not only does evolution and science prove that the human body should run off of fat, but I myself lost 66 pounds in 8 months on keto, my skin is flawless (used to have terrible acne) I have more energy and I'm all around just better, happier and healthier.
