Also "An effective, medically sound diet that lets you eat bacon, eggs, steak, even cheese? It's true!"
Is just wrong. Medically sound my ass. Of course you're going to get people to buy a book that says that you can eat what you want (E.g. lots of animal fats), doesn't make it the right... far from it actually.
As I said before I have nothing against keto/high fat low carb diets but the commonly consumed foods are awful. Basically no micronutrients, mostly animal fats and excessive amounts of protein. Those really aren't doing you much good. If books on keto diet were suggesting nuts, seeds, berries, avocado and some meat that wasn't heavily proccessed as basis of it's diet I wouldn't comment at now I am sure that lots of people are going to look into keto and hop on bacon + eggs all day every day kind of regime.
