The Grapefruit Diet is a 12-day diet program that promises to burn fat. This diet can be extended beyond 12 days, but it is important for the dieter to take 2 days off before continuing the diet. Grapefruit hasn't been scientifically proven to effectively burn fat, but there have been testimonials and stories from The 2 Week Diet Review previous dieters who say that the Grapefruit Diet has worked. A menu under the Grapefruit Diet includes grapefruit, water (about 8 glasses of water should be imbibed daily), black coffee, and vegetables. The enemy of this diet is complex carbohydrates.

Another diet program that can be found online is the Sonoma Diet. This diet relies on the different combinations of food and the amount one can eat. The Sonoma Diet is composed of three waves, which would answer the different weight loss goals and cravings of a person. In the first wave, the cravings for sugar and other food products that led to one's weight gain will be solved. Here, the dieter is taught the proper eating habits that would help him/her succeed at this diet program. It is during this wave when a person's weight loss comes the fastest, thus making him/her more determined and possibly excited to continue with the diet.
