I LOVE this product and this company! The guy who wrote the initial comment is full of it (maybe the competition!?). I am on day 40 and have lost 27 pounds, and I feel great! And it's not 600 calories a day - it's 500. And they DO NOT charge to see their blog! Their phone support is GREAT, and they are open most of the day and night! If it were starvation, then our muscles would be losing tone, and we would be fatigued, have muscle atrophy, etc. - not happening!
