There are many weight loss pills available on the market. But, only a portion of those pills have met with the Federal Drug Administration's approval. An examination of the pros and cons of FDA approved diet aids is the first step to understanding if they are right for you.
What FDA Approval Means
Having FDA approval means the Federal Drug Administration believes a drug has been proven safe. A drug gains this approval through many tests and trials. By the time the approved drug becomes available to the public, it has already been taken by thousands of people over a time span of several years. They have all proven that they can trigger or support weight loss without serious apparent health risk.
Diet pills with FDA approval fit into one of two categories. They are either fat blockers or appetite suppressants. However, even with FDA approval, diet drugs are not miracle cures, nor are they without undesirable side affects.
Fat Blockers
Alli is the only over the counter FDA approved weight loss drug. It, and its prescription strength sister Xenical, are both derivative of a fat blocker called Orlistat. Fat blockers work by binding with the fat in the food you eat and preventing the body from absorbing it.
Appetite Suppressants
Most FDA approved weight-loss drugs are appetite suppressants. Most of those appetite suppressants, such as Adipex-P, Oby-Trim and Zantryl, contain a drug called Phentermine. Phentermine stimulates the neurons in the brain to trigger a fight-or-flight response that shuts off hunger signals.
The most important part of choosing a weight loss drug is to choose one under the guidance of your doctor. Sometimes even FDA approved drugs can have dangerous effects if taken by the wrong person. The best way to lose weight is still by healthy eating and frequent exercise. Talk to your doctor to see if weight loss drugs are a necessary option for you.
