Metabolism describes a chemical reaction that occurs in the body's cells, according to KidsHealth.org. Metabolism converts food into energy for the body. Some diet pills claim to speed up metabolism, resulting in weight loss. Before choosing a metabolism diet pill, however, it's important to evaluate effectiveness and safety.
Types of Pills
Green tea extract diet pills claim to increase calorie burning, fat metabolism and decrease appetite, according to MayoClinic.com. Although this supplement appears to be safe, there isn't sufficient evidence to support its effectiveness. Chromium diet pill makers claim they boost calories burnt, decrease appetite and promote muscle growth. This pill is likely safe, but more research is needed to support effectiveness, according to MayoClinic.com. Bitter orange is another supplement that claims to increase calories burnt through a faster metabolism. Although this pill hasn't been banned by the Food and Drug Administration, it's possibly unsafe, according to MayoClinic.com. Country mallow is another diet pill that claims to boost metabolism through increased calories burned, however this drug was found to be unsafe by the Food and Drug Administration.
An important concern when choosing a diet pill to boost metabolism is safety. Nonprescription diet pills aren't put through the rigorous testing procedures carried out on prescription medications, according to MayoClinic.com. Products are usually discovered unsafe after the products are brought to market. At this point, the Food and Drug Administration will monitor safety and ban unsafe diet pills. Talk with your doctor before taking any diet supplement to determine risks and potential drug interactions.
Diet and lifestyle changes are highly effective methods to boost the metabolism, according to MayoClinic.com. Cutting calories can assist in creating a calorie deficit, which promotes weight loss. Physical activity can also improve your metabolism and help burn calories quicker. Strength training sessions build muscle mass, an important component of weight loss.
Prescription Diet Pills
Prescription weight loss pills undergo a lengthy Food and Drug Administration process to prove drug safety. If you have a body mass index of 27 or higher, your doctor may prescribe these drugs. Orlistat is a long-term prescription weight loss drug that works to block fat absorption, according to MayoClinic.com. Side effects of Orlistat may include intestinal cramps, oil spotting and gas. The Food and Drug Administration is also investigating the drug for potential liver side effects, however, the organization hasn't found a link yet.
Phentermine and Diethylpropion are short-term prescription weight loss drugs, used up to 12 weeks for weight loss. The drugs work to curb appetite. Side effects may include blood pressure increase, increased heart rate and insomnia, according to MayoClinic.com.
Prescription diet pills may result in a 5 to 10 percent loss of body fat over a year, according to MayoClinic.com
Talk with your doctor about weight gain. Underlying health conditions may play a role in unexplained weight gain. For example, excessive weight gain may be caused by an underactive thyroid gland or Cushing's syndrome, according to MayoClinic.com. Your doctor can assist in ruling out these conditions.
