Doctors, dietitians, and nutrition experts rated the keto diet last? What a shocker! For the last 40 years, all of those people have been giving us terrible advice about how to eat--plentiful whole grains, vegetables, and lots of fruit--and Americans have complied. We are sicker, fatter, and more diabetic than any people anywhere in human history. Although getting any controlled trials on keto is tough, a few have been done--showing excellent results in biomarkers for health. Keto reverses type 2 diabetes. Our desire for "extreme" approaches to eating is a direct result of being so SICK and FAT. If eating whole grains, low fats, plentiful veg, and fruit worked, we wouldn't be so desperate. It doesn't work--ask most dieters.
