That's exactly what I started with because of my reading on its theory and praise of it from a financial and computer security blogger I read daily who has written much about it due to his great success with it, but because getting the body into ketogenic mode (ketosis) requires a huge reduction in carb intake requiring much vigilance and because of some negative side effects I had with extremely low carbs, I just went with a low carb diet rather than the extremely low carb ketogenic diet.
Probably easier. I use portion cotnrol. I have lost nearly 50 pounds using portion control.
