If you’ve read any diet books then you know that it can be pretty confusing. Hundred of pages of science, theory, and recipes. Maybe it will help, may not. Are they all really different?
Diet book writers have to focus on a small aspect of your metabolism. So ehy tell you to avoid protein, or carbs, or add fiber or omega 3 oils. Even though they all agree on one thing, we read the books and focus on the other things.
What do they all agree on? You need to eat lots of fruits and vegetables. That’s a good place for you to start.
