Weight Loss Supplements Premium Supplements For Losing Weight & Burning Fat
New Zealand plant scientists have developed a new pill to control appetite that could revolutionise the weight-loss market when it’s released today. This fact sheet describes what’s known about the safety and effectiveness of many ingredients that are commonly used in weight-loss dietary supplements Sellers of these supplements might claim that their products help you lose weight by blocking the absorption of fat or carbohydrates, curbing your appetite, or speeding up your metabolism But there’s little scientific evidence that weight-loss supplements work. Many are expensive, some can interact or interfere with medications, and a few might be harmful.
A 30-year-old man swallowed two different types of diet pills that he bought on the internet. About one hour after taking the pills, he felt very ill and his family brought him to the emergency room. In the emergency room, the patient had a pronounced tremor and a fast heart rate; he was feeling very anxious. The diet pills both contained multiple botanical ingredients, caffeine, and “proprietary blends” which could have included any number of unlisted compounds. The patient developed vomiting and his electrolytes were abnormal. He received treatment with intravenous fluids, medications to stop the vomiting, a sedative, and replacement electrolytes. After about 12 hours of monitoring for seizures and abnormal heart rhythms, his felt better and was released from the hospital.
Ephedra (also called má huáng) is a plant containing substances that can stimulate your nervous system , increase the amount of energy you burn, increase weight loss, and suppress your appetite. In the 1990s, ephedra was a popular ingredient in dietary supplements sold for weight loss and to enhance athletic performance. In 2004, the U.S. Food and Drug Administration (FDA) banned ephedra in dietary supplements, concluding that it isn’t safe. Ephedra can cause nausea , vomiting, anxiety, mood changes, high blood pressure, abnormal heartbeat, stroke , seizures , heart attack , and death.
Complicating the interpretation of many study results is the fact that diet pills that work fast without exercise contain multiple ingredients, making it difficult to isolate the effects of each ingredient and predict the effects of the combination. Evidence may exist for just one of the ingredients in a finished product, and no evidence may be available for an ingredient when it is combined with other ingredients. Furthermore, dosages and amounts of active components vary widely among fat burning pills, and a product’s composition is not always fully described in published studies 14 Studies might also use different and sometimes inappropriate assessment techniques to measure the effectiveness of a given treatment. All of these factors can make it difficult to compare the results of one study with those of another.
Several prescription weight loss drugs have been available in the United States. The Food and Drug Administration approved phentermine in 1959 and approved fenfluramine in 1973 for short-term use (a few weeks). In 1996, dexfenfluramine was approved for longer use (up to 1 year). In 1997, sibutramine was approved for short-term use. These four drugs work by limiting hunger. Orlistat, a drug that blocks the amount of fat absorbed from food, was approved in 1999 for up to 2 years of treatment. Fenfluramine or dexfenfluramine was often used in combination with phentermine; this combined weight loss treatment is known as fen-phen.” Reports of heart valve problems in fen-phen” users led the manufacturer to stop selling fenfluramine and dexfenfluramine in the United States in September 1997. Little is known about how many people actually take these different drugs or how overweight these persons are when they start taking them.
