Garcinia cambogia extract contains the juices from this small fruit and is available as a weight loss pill. Garcinia cambogia may inhibit or prevent a fat-producing enzyme called citric acid lyase. There is little scientific evidence to support the use of this extract to help with weight loss.
According to one report , the effectiveness of the extract in long-term clinical trials and large-scale studies has not been proven. Although garcinia cambogia extract may not aid in weight loss, it does not appear to cause many side effects when taken in reasonable doses. The report above also indicated that adverse effects did not occur with a dietary dosage of up to 2, milligrams mg per day. The body produces pyruvate when it breaks down sugar.
Pyruvate is also sold as a supplement to assist with weight loss by helping break down fat and boosting metabolism. Existing studies are weak, so results are not conclusive. Although more evidence is needed, some research indicates that drinks containing green tea extract may promote the loss of fat around the stomach area. The increase in fat loss may also result in modest weight loss. Although green tea extract is usually well tolerated, it can cause stomach pain, constipation , and nausea.
Conjugated linoleic acid is a type of fatty acid found mostly in beef and dairy. It has been marketed as one of the best weight loss pills for its potential to boost metabolism and decrease appetite. However, the majority of the studies on conjugated linoleic acid leading to weight loss have been carried out on animals. According to a review of research, weight loss appears to be minimal in human studies.
Conjugated linoleic acid appears to be safe in doses of up to 6 grams per day for up to 12 months. Possible side effects include stomach discomfort, diarrhea, or constipation. It may not be suitable for people who have diabetes. Hydroxycut is a popular dietary supplement. There are different Hydroxycut products, which contain various ingredients. Hydroxycut products typically contain plant extracts and caffeine, although caffeine-free versions of the supplement are also available.
If you find yourself overeating because you feel empty, then an appetite suppressant could be a helpful weight loss option. Appetite suppressants work by making you feel full even when you're not. Caffeine is one of the most common ingredients used to limit hunger; it works by dulling the signals from hunger hormones.
Other common appetite suppressants include conjugated linoleic acid, and glucomannan. Glucomannan and other high-fiber ingredients work by expanding in your stomach to give you a feeling of fullness so you'll be less tempted to overeat.
Made from konjac root aka elephant yam , glucomannan is a soluble dietary fiber found in many of the top weight loss supplements. In your stomach, this ingredient absorbs water and expands to make you feel full.
As with all fiber supplements, you'll get the most benefit if you take it before a meal with a full glass of water. Green coffee bean extract comes from raw, unroasted coffee beans and contains chlorogenic acid that would otherwise be lost in the roasting process.
Chlorogenic acid is thought to reduce the amount of glucose and fat your gut absorbs, which lowers insulin levels and improves your metabolism. This popular weight loss supplement ingredient has other health benefits too. Some positives include improved blood pressure and healthier cholesterol levels. Green coffee is also a source of caffeine and therefore has thermogenic properties, increasing your metabolism so you burn calories faster, even at rest.
Garcinia cambogia comes from an Indonesian tropical fruit called the Malabar tamarind. It is an appetite suppressant with thermogenic properties. Scientists say it may help lower blood sugar levels.
The main active factor in Garcinia cambogia is hydroxycitric acid, which stimulates the body to burn fat for energy. The antioxidant benefits of green tea are well documented. It contains a gentle amount of caffeine, which is thermogenic and helps tamp down appetite.
And it's also full of compounds that are believed by some to increase the levels of hormones that tell your cells to break down fat. Some researchers also theorize that the catechins in green tea may reduce the absorption of carbohydrates, so your body may store fewer carbs as fat.
With so many different benefits, it's no wonder green tea is one of the most popular ingredients in weight loss pills! CLA comes from grass-eating animals like deer and goats. Studies link CLA to increased fat burning and weight loss. It comes in a handful of varieties, but c9 t11 is the form most likely to be found in weight loss products.
Caffeine is one of the most common ingredients in weight loss pills, and for good reason. It has several proven benefits for all facets of life. Speeding up your metabolism burns calories, and caffeine has the bonus effect of promoting the breakdown of fat.
Additionally, we all know that exercise is an important part of any weight loss plan. It's a mood lifter too, and it suppresses feelings of hunger. Basically, caffeine is the weight loss bomb! A raspberry ketone is a molecule naturally found in blackberries, cranberries, and other fruits. Scientists have discovered that raspberry ketones help mice break down fat, control blood sugar levels, and regulate their metabolism.
Orlistat is a prescription drug in most of the world, but it is sold over the counter as Alli in the US and UK. It is intended to treat obesity in conjunction with a doctor-supervised low-calorie diet. Orlistat decreases the amount of fat that people can absorb after eating.
In your intestines, an enzyme called lipase is responsible for breaking down fat. Orlistat blocks the action of lipase so your body can't store the fat, passing it on through the digestive system instead.
Orlistat also reduces blood pressure and appears to prevent the onset of type 2 diabetes. Side effects may include soft stools and gassiness. Contrave is a combination of two established medicines—naltrexone and bupropion.
Naltrexone is used for treating addiction, and bupropion is an effective antidepressant. Together, they can eliminate hunger pangs, uplift mood, and control cravings. In studies, this prescription weight loss drug was shown to double the number of test subjects who achieved their weight loss goals compared to a placebo.
Potential side effects include dizziness, nausea, and constipation. As you might guess from the name, Phentermine is a type of amphetamine. It is a CNS stimulant that elevates heart rate and decreases appetite. It is a commonly used weight loss drug for people with high cholesterol or diabetes. One downside of Phentermine is the tendency for people to become used to it. The beneficial effects can be reduced after just a few weeks.
Other potential side effects include headaches, dizziness, chest pain, and difficulty breathing. Belviq reduces appetite by activating a type of serotonin receptor in the section of the brain that controls appetite, so you feel full even after a small meal. It is used for the long-term treatment of obesity.
While Belviq can help you lose weight, it does nothing to treat the underlying issues that caused weight gain in the first place. Also, this prescription weight loss pill won't improve cholesterol levels, diabetes, or heart disease. Some potential side effects can include nausea, sore throat, irregular heartbeat, and seizures.
Xenical is the prescription-only version of Alli Orlistat. Both work to prevent the body from absorbing dietary fat, but Xenical delivers a higher dose.

Prescription weight-loss drugs approved for long-term use more than 12 weeks produce significant weight loss compared with placebo.
The combination of weight-loss medication and lifestyle changes results in greater weight loss than lifestyle changes do alone. That may seem like a modest amount. Mild side effects, such as nausea, constipation or diarrhea, are common. They may lessen over time. Rarely, serious side effects can occur.
For this reason, it's important to thoroughly discuss treatment options with your doctor. Weight-loss drugs can be expensive and aren't always paid for by insurance. Ask your insurance company about coverage. Many people gain back some of the weight they lost when they stop taking weight-loss drugs. However, adopting healthy lifestyle habits may help limit weight gain. How long you'll take a weight-loss drug depends on if the drug helps you lose weight.
If you've lost enough weight to improve your health and you haven't had serious side effects, your doctor may suggest that you take the drug indefinitely.
