Diet drugs are available in several different forms, including prescription drugs, over-the-counter drugs and herbal supplements. A­Prescription drugs such as Meridia and Xenical are only available with a doctor's prescription.
Over-the-counter drugs are available without a doctor's prescription, right in your local drugstore or supermarket, and are also regulated by the FDA.
A­ There is also a selection of diet aids that are administered by patch, as a powder or in liquid form.
In this article, we will look at the wide variety of diet pills available, find out how they work and what their side effects are and see if they live up to their promises. Washington, March 7 : Weight loss supplements are not really effective in helping you shed weight and may have unpleasant or serious side-effects. Melinda Manore, from Oregon State University, reviewing evidence surrounding hundreds of weight loss supplements, concluded that no single product results in significant weight loss and many have side-effects. A few products, including green tea, fibre and low-fat dairy supplements, can have a modest weight loss benefit of three to four pounds, but it is important to know that most of these supplements were tested as part of a reduced calorie diet, the International Journal of Sport Nutrition and Exercise Metabolism reports.


Manore looked at supplements that fell into four categories: products such as chitosan that block absorption of fat or carbohydrates, stimulants such as caffeine or ephedra that increase metabolism, products such as conjugated linoleic acid that claim to change the body composition by decreasing fat, and appetite suppressants such as soluble fibres. She found that many products had no randomized clinical trials examining their effectiveness, and most of the research studies did not include exercise. Manore said the key to weight loss is to eat whole grains, fruits, vegetables and lean meats, reduce calorie intake of high-fat foods, and to keep moving.
With more than 60 percent of Americans now considered overweight or obese, diet drugs have turned into a multibillion dollar industry in the United States. They are carefully regulated by the Food and Drug Administration (FDA) Center for Drug Evaluation and Research, and their use is closely monitored by the prescribing doctor. You'll typically find a huge variety of these in health food and nutrition stores as well as in regular supermarkets. These types of drugs may fall into any of the above categories -- it is only the delivery method that is unique. Most of the products showed less than a two-pound weight loss benefit compared to the placebo groups.


The data is very strong that exercise is crucial to not only losing weight and preserving muscle mass, but keeping the weight off," said Manore, professor of nutrition and exercise sciences at Oregon.
OTC drugs also fall under the jurisdiction of the FDA's Center for Drug Evaluation and Research.
Weight-loss questions aside, several diet drugs over the last decade have been associated with serious heart problems and other health-related issues, and diet pills have even been linked to a number of deaths.
As such, they fall under the jurisdiction of the FDA's Center for Food Safety and Applied Nutrition and are regulated differently from OTC drugs.
