I have lost 25 lbs. and almost 21 inches. The program is set up for the average person. You don't have to have a ton of will power, the program does that for you. If you are serious about getting the extra weight off, this is the way to go. I was always tired, and had a very hard time even getting out of bed in the morning. My body hurt from my head to my toes. Thanks to this program I no longer feel that way anymore. I have all the energy I need and I keep up with my daughter. I can even outlast her.
