I am 58 years old and have been on the program for 2 months with incredible results. I have already lost over 20 pounds and 19 inches. It is not just the weight loss that is incredible but the way my body is changing. I had almost given up hope of ever being at my goal weight but now I know I can get there. Jane is great and the weekly meetings are helpful not just for motivation but the knowledge I am getting from Jane . The scientific basis for this makes so much sense. I am so much healthier than when I walked in the door. I believe this truly is the last diet I will ever be on.
