As noted above, caffeine stimulates the release of adrenaline, which boosts metabolism and increases fat burning. EGCG enhances these effects by slowing the breakdown of adrenaline so that its impact is amplified 6 , 7.

One review found that overweight or obese people who consumed green tea supplements daily for at least 12 weeks lost only 0. However, a different review found that individuals who took green tea supplements for the same time period experienced an average weight loss of 2.

More research is needed to better understand how green tea affects metabolism and body composition. Capsaicin is the molecule that makes chili peppers spicy — the spicier the pepper, the more capsaicin it contains. Like caffeine, capsaicin stimulates the release of adrenaline, which speeds up metabolism and causes your body to burn more calories and fat It also reduces appetite, making you eat fewer calories.

Together, these effects make capsaicin a powerful thermogenic substance A review of 20 studies found that capsaicin supplements can boost metabolism by about 50 calories per day, which could lead to significant weight loss over time Another study showed that dieters taking 2. Supplementing with 6 mg of capsaicin daily has also been linked to reductions in belly fat over a three-month period However, there is some evidence that your body can adapt to capsaicin, reducing these effects over time Garcinia cambogia is a tropical fruit whose extracts are often used in weight loss supplements.

It contains a compound called hydroxycitric acid HCA that can block the activity of the enzyme ATP citrate lyase, which is involved in the formation of body fat This is a difference of roughly 2 pounds 0. More studies are needed to understand whether garcinia cambogia supplements are effective for weight loss or reducing body fat.

Yohimbine is a chemical derived from the bark of the African yohimbe tree, and is commonly taken as a thermogenic supplement.

It works by increasing the activity of several hormones, including adrenaline, noradrenaline and dopamine, which could theoretically boost fat metabolism 22 , The effectiveness of yohimbine for fat loss has not been researched much, but early results are promising.

Yohimbine may be especially effective for weight loss when combined with exercise, since it has been shown to boost fat burning during and after aerobic exercise At present, there is not enough research to determine whether yohimbine truly helps burn body fat.

Bitter orange, a type of citrus fruit , contains synephrine, a compound that is a natural stimulant, similar in structure to ephedrine. While ephedrine has been banned in the United States due to reports of sudden heart-related deaths, synephrine has not been found to have the same effects and is considered safe to use in supplements Taking 50 mg of synephrine has been shown to increase metabolism and burn an additional 65 calories per day, which could potentially help people lose weight over time A review of 20 studies using bitter orange alone or in combination with other herbs found that it significantly increased metabolism and weight loss when taken daily for 6—12 weeks Since many substances have thermogenic effects, companies often combine several of them in one supplement, hoping for greater weight loss effects.

Studies show that these blended supplements provide an extra metabolism boost, especially when combined with exercise. However, there have not been many studies to determine whether they reduce body fat 29 , 30 , 31 , One eight-week study found that overweight and obese dieters who took a daily supplement containing green tea extract, capsaicin and caffeine lost an additional pound 0.

Yet, more research is needed Popular thermogenic supplements include caffeine, green tea, capsaicin, garcinia cambogia , yohimbine and bitter orange. These substances can boost metabolism, increase fat burning and reduce appetite, but the effects are relatively small. While thermogenic supplements may sound like an appealing way to boost your metabolism and reduce body fat, they do have some risks and side effects.

Many people tolerate thermogenic supplements just fine, but they can cause unpleasant side effects in some 34 , The most common complaints include nausea , constipation, abdominal pain and headache.

Supplements containing mg or more of caffeine may cause heart palpitations, anxiety, headache, restlessness and dizziness Several studies have reported a link between these types of supplements and severe inflammation of the intestinal tract — sometimes hazardous enough to require surgery 37 , Others have reported episodes of hepatitis inflammation of the liver , liver damage and even liver failure in otherwise healthy teens and adults 39 , 40 , 41 , Always examine ingredients and speak with your healthcare provider before deciding whether thermogenic supplements are right for you.

The most common side effects of thermogenic supplements are minor. However, some people experience serious complications, such as inflammatory bowel disease or liver failure.

Always use caution and speak to your doctor before taking a new supplement. They may be more effective when paired with other diet and exercise changes but are not a magic pill solution. Always speak with your doctor before trying a new supplement, since some people have experienced serious complications.

Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. There are several effective supplements that can help you burn body fat. This article lists 5 natural fat burners that are supported by science.

Caffeine is a natural stimulant consumed throughout the world. This article reviews caffeine and its health effects, both good and bad. Many studies show that green tea can help you lose weight. It contains bioactive substances that can make you burn more calories, even at rest.

People have used cayenne peppers medicinally for thousands of years. They're also nutritious and great for cooking. Here are 6 benefits of cayenne….

This may be beneficial for some people on a weight loss journey. Whilst caffeine stimulates the release of adrenaline, which boosts metabolism, EGCG enhances these effects by slowing the breakdown of adrenaline so that its impact is amplified.

However, it is still unclear whether this leads to actual weight loss results. One study found that overweight people who were given green tea supplements daily for at least 12 weeks lost only 0. Not exactly great results. Capsaicin is the molecule that makes chilli peppers spicy — the spicier the pepper, the more capsaicin it contains.

Just like caffeine, capsaicin stimulates the release of adrenaline, which speeds up metabolism, causing your body to burn more calories. It also reduces appetite, which may help you eat fewer calories.

Together, these effects might actually have an impact. A review of 20 studies found that capsaicin supplements can boost metabolism by about 50 calories per day, which is certainly a much higher amount than good old caffeine. However, there is some evidence that your body can adapt to capsaicin, reducing these effects over time.

So, on the whole, using thermogenics may not be the way forward and certainly not as your only means of losing weight. However, combined with exercise and a sensible diet as well as their appetite-suppressing effects, there may be an argument for including them on your weight loss journey.

In my experience weight gain or loss is multifactorial, and a combination of approaches is usually best. It is also true however that some foods have a higher thermic effect than others.

Out of the macronutrients for example protein is by far the best choice for weight loss as it requires the most energy in order to be broken down. Some of the best foods to include are fish and seafood as well as lean meats and eggs. Beans and legumes, tofu or tempeh and of course high protein seeds such as hemp are the best alternatives for those on a plant-based diet.

Be aware though that while many people tolerate thermogenic supplements well, they can cause unpleasant side effects in some; nausea, constipation, abdominal pain and headaches are not uncommon. As mentioned above, thermogenics work by increasing metabolism which can cause an increase in blood pressure.

If high blood pressure is an issue for you, you may wish to steer clear. Very high-dose caffeine supplements containing g or more can also cause heart palpitations, anxiety and dizziness.

Finally, several studies have reported a link between these types of supplements and intestinal inflammation. As a nutritional therapist , I do not usually recommend these types of supplements in my clinic although I have found them incorporated into blends, especially protein shakes and pre-workout drinks.

Where this is the case, I am usually happy to include them. As long as it is at low doses I feel that they can only have a positive impact. In my experience weight gain or loss is multifactorial, and a combination of approaches is usually best, so adding the occasional thermogenic to the toolbox as part of a blend of nutrients is something I would consider a benefit.

If you are considering using these without supervision my advice would be to exercise caution and know that when it comes to weight loss, there simply is no magic pill.

From promoting feelings of fullness, you will essentially eat fewer calories. Recent evidence suggests that Turmeric may help promote weight loss. Turmeric contains compounds with anti-inflammatory and medicinal properties called curcuminoids.

The most vital compound within turmeric is its active ingredient curcumin. A large body of evidence shows that in addition to curcumin, turmeric contains over one hundred unique chemical properties that contribute to its countless therapeutic and anti-inflammatory effects.

Research suggests that curcumin has protective effects against regaining weight, through the inhibition of adipose tissue growth and increasing insulin sensitivity [ R ].

The results showed that curcumin increased weight loss, 1. Although this is a preliminary study, the findings suggest that curcumin could positively influence weight management [ R ]. A systematic review on the effects of ginger on weight loss and metabolic rate on obese individuals, found that ginger may help reduce body weight and fasting glucose levels [ R ].

Another study published in the journal Metabolism found that ginger enhances the thermic effect of food and promotes feelings of fullness [ R ]. Ginger contains compounds called gingerols which increases thermogenesis and stimulates lipolysis.

Including these thermogenic foods into your nutrition plan is a sustainable way to consistently burn more total calories while also maintaining muscle mass. We believe that everyone can optimize not only their athletic performance but their human potential.

The way we believe we can optimize performance is through transparency, clinically effective doses, and clinically proven ingredients with evidence-based outcomes.

Curcumin limits weight gain, adipose tissue growth, and glucose intolerance following the cessation of exercise and caloric restriction in rats. J Appl Physiol Some manufacturers recommend taking high doses multiple times per day, for example 30 to 60 minutes before every meal, for eight to 12 weeks straight, which can wind up causing toxicity.

Yohimbe or yohimbine is an herbal supplement. Yohimbine may have certain fat-burning abilities and work even better while someone is fasting. Given that yohimbine can act as a mild stimulant, researchers have looked at whether it can help increase energy levels in those looking to become more active, or whether it has positive effects on reducing appetite, regulating blood sugar levels, or promoting growth of muscle mass that can then help with weight loss.

Although not every study has shown that yohimbe can have slimming effects, certain other studies have found positive results. One study found that yohimbine significantly increased mean weight loss in overweight female patients following a low-energy diet.

Possible mechanisms of action include : boosting lipolysis the breakdown of fats and other lipids by releasing fatty acids into the blood both during and following exercise, regulating insulin secretion, and reducing appetite. Yohimbe also may act as a mild hallucinogenic, causing neurological reactions that can be wide-ranging.

for erectile dysfunction but has undergone resurgence in street use as an aphrodisiac and mild hallucinogen. Cayenne pepper and its molecular compound found capsaicin is a shrub that originated in Central and South America and now grows in subtropical and tropical climates.

Its hollow fruit grows into long pods that turn red, orange or yellow when they ripen. A study published in PloS One noted that consuming cayenne pepper for breakfast creates less appetite , so people eat less calories during the day.

As one of the key anti-inflammatory foods , cayenne pepper benefits also include weight loss. In recent years, forskolin supplements have been used to promote weight loss. There have been very few reputable studies regarding forskolin and its impact on weight loss in humans.

The first human research investigating the effects of forskolin on weight loss was conducted in at the University of Kansas and involved 30 overweight or obese men. This week study involved each man taking either a placebo or milligrams of a 10 percent forskolin extract orally two times each day.

It found forskolin to have a positive impact on body composition, decreasing body fat percentage and fat mass. Later that year, a second human study conducted at Baylor University that was published in the Journal of the International Society of Sports Nutrition was conducted with 23 mildly overweight women.

They were given the same dosage as the men in the first study, also for a week period. In addition, no significant differences were found in any metabolic markers or blood lipids such as increased testosterone found in the first study.

They did postulate that forskolin seemed to prevent the development of new fat mass. They found that the subjects taking it reported less fatigue, hunger and fullness. Raspberry ketones are chemicals from red raspberries that are used for their flavor and fragrance.

There are some studies involving rodents that have mixed reviews, but suggest that raspberry ketones may help to reduce food intake and thereby promote weight loss. A animal study out of Ohio State University found that raspberry ketone supplementation has limited benefit in fat loss beyond reducing food intake in mice fed a high-fat diet.

Taurine is a type of amino acid that is found in the tissues throughout the body. It can also be produced in small amounts. Taurine, or 2-aminoethanesulfonic acid, is a type of amino acid that is found in the body and is considered the most abundant amino acid in the heart, retina, skeletal muscle, brain and immune cells.

L-taurine is often added to energy drinks for those looking to take advantage of the potential taurine benefits. It is believed to be associated with a number of health benefits, such as increased fat-burning during exercise and improved heart health.

Thermogenic supplements can cause side effects, some severe, or longer-lasting health problems. Here are some of them. As one of the largest organs in the body, the liver supports many essential metabolic functions, including transforming nutrients from the foods we eat into substances our bodies can use, processing harmful substances and breaking down fat for energy.
