Losing weight is not a magic. The only way to lose weight and keep it off is through indefinite lifestyle changes: Eat healthier, low-calorie foods, watch portion sizes, and engage in regular physical activity. It's certainly no magic pill, but it works.
Keep in mind that even if you take a weight-loss pill, you still have to eat fewer calories than your body uses in order to lose weight. Even if these products were to help you lose weight initially, you'd have to continue taking them for the weight to stay off, which is neither practical nor safe.
Weight Loss Products and their facts
Diet drink powdered formulas usually are mixed with a glass of milk and are substituted for one or more meals. Many users of these shakes report feeling constantly hungry and regain the lost weight when they give up the shakes. By relying on shakes, dieters follow artificial dieting methods and avoid learning how to work food into their lives.
Many prescription diet medicines have side effects and may not work for long-term weight loss. Over-the-counter pills containing the appetite suppressant PPA (phenylpropanolamine hydrochloride) can raise blood pressure.
Herbalife Nutritional Program - Replaces 2 meals a day with Herbalife "shakes" and tablets. One meal per day of regular food advocated. Shakes generally include nonfat dry milk.
Nestlé’s Sweet Success - Weight loss program recommends three shakes/ day (powder and skim milk), and a complete dinner of 500 to 650 calories. It is low-fat, nutrient rich foods are encouraged for dinner.
Diet Pills Containing PPA - Take capsule once or twice a day. Follow diet plan that comes with capsules. Pills suppress appetite, but weight loss occurs from following diet plan.

Facts of Weight Loss Products
Any claims that you can lose weight effortlessly are false. The only proven way to lose weight is either to reduce the number of calories you eat or to increase the number of calories you burn off through exercise.
Very low-calorie diets are not without risk and should be pursued only under medical supervision.
Fad diets rarely have any permanent effect. Sudden and radical changes in your eating patterns are difficult to sustain over time.
