None of them.. its a complete waste of time and money..
Remember there are no quick fixes.. diet and exercise is the only way to go

You didn't take a pill to get fat, so don't rely on a pill to make you thin.
Researchers at at George Washington University and Georgetown University have found that the best diet for weight loss, lowering blood pressure and preventing diabetes is a vegetarian diet. A diet low in fat (30 g or less) and high in complex carbohydrates and fiber. in order to get the complex carbs, do not eat white bread, pasta, white rice, and avoid precessed foods. Do all of your grocery shopping in the produce section. Avoid the use of meat. You can get all of your protein from plants. Also, do not drink soda pop or sports drinks because these are these are the source of the most useless calories that are consumed by young people today.
Don't forget to exercise. The only true way to loose weight is to use more calories than you consume. Eat right and exercise, and the weight will come off in a slow steady rate that it will stay off.

non, it's unhealthy for you.
