According to the JAMA (Journal of the American Medical Association) an astounding 64% of the US adult population is either overweight or on the verge of becoming obese. The alarming fact is that this percentage is moving northbound pretty fast. On a global scale it is estimated that more than 1 billion of the population is overweight or obese and a steady rise in this trend has been observed in all age groups. No wonder, all over the world, particularly in the developed countries, more and more people are trying out different ways to cut down their weight. In this scenario, slimming pills have become a major rage among people looking for an easy remedy. This is because these promise to lower weight quickly and without subjecting the individual to grueling workout regimes or strict diet.
There are quite a number of these pills available in the market today, both in the form of prescription drugs and as over-the-counter drugs. One of the major advantages of taking the prescription drugs is that it gives you the reassurance that it is safe and effective because, before these drugs are allowed into the market, they needed to undergo years of clinical trials and obtain approvals from the FDA. This means that their efficacy has been tested and they have been proved to have minimal side effects. On the other hand, though the over-the-counter slimming pills make tall claims, often fraudulent, usually do not have such scientific endorsement behind them and may have serious side effects, too. However it is the ease of their availability compared to the limited prescription drugs which makes them an attractive option to people looking for a quick solution without the hassles of a prescription.
Another class of drugs, which has become quite popular nowadays and has been touted as being completely free from side effects, is the natural drugs or herbal drugs. Contrary to their claims, these slimming pills can not only have dangerous side effects but may even contain harmful ingredients. It had taken almost half a decade before FDA could ban the sale of ephedra as a herbal ingredient in such formulations. It was found that this ingredient had caused damage to the nervous system and was responsible for a range of cardiac failures in people who had used them.
Another aspect in which these slimming pills differ from other drugs is in its method of action. Most of them can be divided into either fat burners or appetite suppressants or fat blockers.
Fat burners, as the name suggests, facilitates the breakdown of fat internally by consumption by the body.
Among the most popular types are the appetite suppressants or anorexiants that cut down on the overall sensation of hunger, thus promoting the sensation of being full with minimal food in-take. Some popular ones are Phentermine, Meridian, Acomplia etc.
The third type of drugs includes the fat blockers. For example, Xenical. It works by acting on the lipase enzyme which is required for the absorption of fat in the body. But it, too, has been proved to have its own share of side effects.
The market, today, is filled with new drugs approved by the FDA such as the Belviq and Qysma. These newer drugs have been tested to have far lesser side effects than the older generation slimming pills.
All the same, whichever brand of pills one takes, it is best to combine the effects of the pill with a proper workout and diet regime for optimum benefit.
