Those commercials are sickening. If they'd lost that much weight in the time that they say they have they wouldn't be all toned up and firm. Toning takes about again as long if not longer than losing the weight unless you exercise constantly and loose the weight slowly. Besides, on an average height woman 20 is one dress size. There's no way a 28 lb weight loss could result in a 3 size reduction. Use to be that the different people portraying one that had lost weight was obvious now with computer enhancement they can use the same people.
