I participated in Dr. Fountis' diet plan. Over a period of four months I was able to lose 70lbs and finally get back to a healthy weight after 10 years of being overweight. More importantly I've been able to maintain the weight for what is now 7 months. The plan is rigorous and you have to follow it exactly but when you do it is relatively easy to stay on. The first week is a little tough to get used to, but after that, the only impact is low energy. I would recommend it for anyone who needs to get back to a healthy weight. The staff is friendly and accommodating and Dr. Fountis is a background with Cleveland Medical which made me so much more comfortable that the diet was legitimately based in good medical practice. It's also affordable. If you look at the price by pound lost it's cheaper than any average diet out there in the market like atkin's, south beach, weight watchers, etc. Overall it was a very good experience and I was extremely happy I did it.
