i was on it 3 years ago and lost 25 lbs. You eat everyday food and it makes you aware of what you are eating. Example you can have a 2 small pieces of candy or an apple, which will fill you up more? I was discouraged at first because i felt like i was hungry all the time and the first 2 weeks my weight wasnt coming off then all of a sudden it was 1lb, then 3 lbs and each week after i was steadily losing. During the holidays this year i got off track because i LOVE baking and had too many sweets, but i am now watching what i am eating again and hope to lose the 5 lbs i put on. Stick with it and be accountable for what you eat and it will work.
