First of all, diet pills are made especially for obese individuals who are striving to lower their weight to normal levels. And those who are prescribed these diet pills are often also required to adopt a low-fat, low-calorie diet and develop an exercise regimen as well. Diet pills are not a magic cure-all that will assure immediate and effective weight loss, particularly those you can get over the counter.
Diet pills are either in the form of prescription drugs or over-the-counter weight loss supplements. Prescription diet pills, which are administered to those with a Body Mass Index above 35, can only be bought with permission from your doctor. Examples of the more popular prescription diet pills are Meridia / Sibutramine, Adipex, Phentermine, Didrex, Bontril, Tenuate, and Xenical / Orlistat. Xenical is one of the more popular prescription drugs at the moment, and it works by preventing the body from absorbing fat. It also prevents the body from absorbing other nutrients as well, which is why Xenical users also take vitamin supplements.
On the other hand, there are several over-the-counter diet pills that may seem to do things to your body to help you lose weight, but don't actually do the trick. For example, Chitosan is touted to trap the fat from the food you eat and discard it without getting absorbed by your body. While Chitosan actually does have fat-trapping properties, it cannot trap a significant enough amount to ensure weight loss.
Unlike prescription diet pills, most over-the-counter diet pills lack scientific testing and verification, and are registered as food supplements, like vitamins. They haven't shown effective weight loss effects, except for some when taken in large doses, such as Chitosan, which can actually be pretty harmful in the long run.
Another example is Chromium, which is advertised as able to melt down fat. What Chromium does is actually help in the metabolism of carbohydrates and fats, and regulates blood levels, as it does naturally in the small amounts found in a lot of the food we already eat. Thinking that Chromium may metabolize more carbohydrates and fats when taken in larger amounts has promoted its existence as a diet pill. Studies have shown that an excess intake of Chromium may cause harm to your liver and kidneys.
"Natural" diet pills may also seem like the healthy option, and while they may help raise your metabolism and keep your hunger at bay, relying solely on diet pills to help you lose weight is still not the safest option. No matter how impatient you may be, find a diet and exercise plan that works for you and stick to it. If your Body Mass Index is above 35 and you need to address your obesity, you may see your doctor for a prescription for the relatively safer diet pills, but also ask him about lifestyle changes and a good diet plan, too.
