Based on a person's weight loss goal, they can receive a customized Fiber35 diet program through their website. The plan divides itself into three distinct phases.

What quickly becomes apparent is the hard sell of their related fiber supplements. In Phase 1, dieters should eat two bars and two shakes a day. In Phase 2, they must eat a single shake and one bar per day.

Simply go into just about any health food store and find these products conveniently stationed next to a copy of the book. Watson maintains that the products are 100 percent natural and have no extra sugars or preservatives.
