The Keto diet is really just an updated and copy of the Atkins Diet and everyone laughed at him 40 years ago. Fact is it works. Zero breads, sugars, potatoes, etc, etc. on a very low carb diet after a week your craving for sugars will slowly decrease but you can not cheat. Eat cheese, steak, chicken, burgers no bun, etc as often as you want. It’s easy but hard at the same time but it does work. It’s worth reading his book.
