Do Diet Pills Really Work?

Many over-the-counter diet pill manufacturers say their product will help you see miraculous weight loss -- like losing up to 30 pounds in 30 days -- without diet or exercise. Their claims sound too good to be true, and most of them are.

A few pills, especially the newer prescription varieties (such as Meridia and Xenical), have been shown in clinical studies to help dieters shed a few pounds. But the majority of the ads you see on the Internet and TV are for products that are unregulated, untested and unproven.

Even the most effective diet pills are only meant to be taken for a short period of time -- usually six months or less. During that time, doctor-prescribed weight-loss drugs can trim anywhere from 5 to 22 pounds, or up to 10 percent of your body weight. But after six months, your body develops a tolerance to these drugs" effects, and weight loss plateaus. After that, if you don"t also follow a healthy eating and exercise plan, the weight will come right back.

Let"s face it, nutritious food, regular exercise and plenty of rest are the foundation stone for proper weight and health.
