There are many kinds of weight loss drugs on the market, and they are very popular, because they all advertise that you can lose weight without exercising or dieting. It sounds very attractive, but is it really effective? Let’s take a look at the effects of the following weight loss drugs:
Drugs that increase metabolic rate
Most of these medicines contain ephedrine, which is derived from a plant called ephedra and can also be manufactured artificially. Ephedrine has been used to treat asthma for many years, and it is also a commonly used cold medicine in Chinese medicine. As a diet pill, it is often mixed with caffeine in the same formula. Caffeine can slightly increase the metabolic rate, while ephedrine can help suppress appetite, but it can cause high blood pressure, irregular heart rhythm, insomnia, nervousness, tremors, seizures, heart disease and stroke, and even death in severe cases . Taking this into account, the U.S. Food and Drug Administration stipulates that these products can only contain a maximum of 8 mg of ephedrine per serving and cannot be used continuously for more than 7 days. The safety of long-term use is still unknown.
Appetite suppressants
Some of these medications contain phenylpropanolamine hydrochloride, a stimulant commonly found in cold medications. These drugs are considered safe for people without cardiovascular problems and high blood pressure, but after stopping the drug, diet control is still required to prevent weight gain.
Fat burning drugs
Many people say that chromium can burn fat. Although it is closely related to fat metabolism, only people who lack chromium will have problems with fat metabolism. Consuming more chromium than needed does not accelerate fat consumption, so it is not effective for people who are not deficient in chromium, and the US recommended nutritional intake is 50 to 200 micrograms of chromium per day for adults.
Other weight loss drugs
As for Hypericum perforatum, the FDA says the substance has not been proven safe and effective for weight loss. Another drug, garcinia cambogia, was reported in the November 1998 issue of the Journal of the American Medical Association that the herb and products containing it were ineffective for weight loss.
It can be seen that the safety and effectiveness of weight loss drugs must be considered when choosing weight loss drugs. Weight loss drugs have one thing in common, that is, there is no instruction on how to improve their eating habits, so most of them regain their weight once they are stopped. There is no unearned gain in this world. Controlling diet and exercising is the best, healthiest and safest way to control your weight for a long time.
