A diet pill is any pharmaceutical that has the effect of suppressing appetite, speeding up a patient's metabolism, or affecting it's absorption of calories. They are generally used by obese patients in an attempt to lose weight. However, many patients do not benefit from such medication and are directed towards healthier alternatives, such as having a better diet and doing more exercise. All diet pills have adverse side effects, and for a physician to recommend their use, the risk from the side effects have to be outweighed by the benefits of the possible weight loss.

The only diet pill currently approved by the FDA for long term use is orlistat, which prevents the body from absorbing fat in the diet. Another common drug is sibutramine, which suppresses appetite. One of the newer appetite suppressants is rimonabant. Metformin, which affects sugar uptake in the liver, is often found to be safe and effective in obese patients with diabetes mellitus. Also there are some Weight loss pills that can help people in process of loosing weight like Pure capsicum plus but none of them are made for actually a weight loss fact. The key to a good weight loss program is healthy diet and exercise. There are also several non-prescription, on the market which assist in weight loss.
