I'm one of 4 people who tried the same diet. We are all IRL friends with the original author, and he got us into it. It worked for all of us.

I lost 60lbs in 40 weeks using this diet, and only felt healthier as I went along.

I didn't get headaches, and caffeine is an indirect appetite suppressant in that it makes me more interested in what I'm doing and less distracted by hunger.
