Fat Melting Weight Loss Products Are Being Heavily Advertised

Have you ever felt tempted to try one of those fast-acting fat-melting weight-loss products that are being heavily advertised? Maybe you got tired of dieting and going to the gym and just want to get rid of the excess pounds quickly. But there’s something you should know about these drugs. They are prescription medications that are intended only for extremely obese persons or whose weight-related problems have reached a critical level and need a drastic remedy. This article will give you basic information about these drugs so you can find out if they’re right for you.

Guidelines have been established concerning prescription of these drugs. One of these is a body mass index (BMI) over 30. The BMI is the ratio of your body’s lean mass (muscle, bone, organs, etc.) to fat mass (basically the fat in your body). The BMI requirement is reduced to 27 if the person has hypertension, diabetes, or heart problems. The doctor has to decide whether a severe condition is obesity-related, in which case you may get a second opinion if you disagree with his evaluation. These medical problems can become life-threatening and the fat-melting drugs may be just what you need.

Most Diets Drugs Keep Your Appetite in Check

These weight-loss drugs have been on the market for decades, with most of them formulated to work their “wonders” by keeping the appetite in check. Dexedrine and amphetamines, which are among the precursors of these drugs, have been around since the 1950’s. Meridia, a new kind of appetite-suppressant drug, has been found “moderately effective in producing weight loss in individuals, with 85% losing at least 5% of body weight and 57% at least 10%.”  However, it has also been found to cause hypertension and depression, and may impair a person’s thinking or reactions.

Another class of drugs – called lipase inhibitors – works by impeding the body’s ability to absorb fat from food. The popular drug Xenical was the first of such medications to get FDA approval. This kind of drug obstructs the body’s production of lipase, a vital part in the absorption of fat. Lipase is the enzyme that metabolizes the fat. In the absence of this enzyme, the fat molecules remain intact and simply pass through the digestive tract to be eliminated. This is why Xenical users have complained of flatulence, cramps, diarrhea, and an oily fluid leaking anally. These are some of the result of having unmetabolized fat leaving the body.

New Medicines Approved By The FDA

Weight-loss drugs are a multi-billion dollar industry, so leave it to the pharmaceutical manufacturers to continue coming up with new and better products for mainstream use. In fact some new medicines had been granted provisional approval by the FDA but had proved to have too many side effects. Eventually some new drugs now being tested and fine-tuned will hit the market as the next generation of weight-loss medications.
