Research has shown that caffeine can increase thermogenesis. According to a review article published in Obesity Reviews , six different studies have found that people burn more calories when they take a minimum daily dose of milligrams mg of caffeine.

To put that in perspective, most caffeine supplements contain mg of caffeine, while one cup of coffee contains about 95 mg. However, if you drink caffeine on a regular basis, this effect might be lessened.

Talk to your doctor before adding more caffeine to your diet. If you drink too many sweetened coffee drinks or chai tea, you could actually find yourself gaining weight! Capsaicin is the chemical that puts the hot in jalapeños.

In fact, a review of 20 research studies, published in Appetite , found that capsaicin can increase the amount of calories you burn by approximately 50 calories a day. Those calories can add up over time, contributing to long-term weight loss.

So consider spicing it up in your kitchen! L-carnitine is a substance that helps your body turn fat into energy. While your body produces it in your liver and kidneys, you can also find it in meat, dairy products, nuts, and legumes. L-carnitine may be helpful for treating a number of conditions, including heart disease, peripheral artery disease, and diabetic neuropathy.

But its use as a dietary supplement for weight loss is questionable. One study reported in the Journal of Medicinal Food found that L-carnitine might provide some anti-obesity benefits.

But more research is needed to assess the benefits and risks of taking L-carnitine supplements for weight loss. According to the Office of Dietary Supplements , taking too much of it can cause potentially dangerous side effects. Chromium is a mineral that your body uses in small amounts.

Chromium picolinate supplements are useful for people who have a chromium deficiency. So far, researchers have given it a thumbs-down. A pilot study reported in the Journal of Alternative and Complementary Medicine found that chromium picolinate supplements had no effect on weight loss.

As with many supplements, research on CLA has found mixed results. A review of studies published in the European Journal of Nutrition found evidence that CLA may promote weight loss and fat loss, but the effects were small and uncertain.

Gastrointestinal problems and fatigue are common side effects of taking CLA supplements, so you may want to pass on this one. Numerous studies have been conducted on the effectiveness of green tea for weight loss.

Few have reported significant results. One study published in Physiology and Behavior does suggest that catechins and caffeine found in green tea may help support weight maintenance. Resveratrol is a substance found in the skin of red grapes, mulberries, Japanese knotweed, and peanuts.

Studies suggest it does burn fat in rats. More clinical trials are needed. Despite the hype, supplements that are promoted as fat busters and metabolism boosters rarely have a significant effect on weight loss. If you want to shed excess pounds, cutting calories from your diet and exercising more regularly are probably your best bets.

Ask your doctor for more advice on losing weight in safe and sustainable ways. And talk to them before trying any weight loss medications or supplements. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

A study on mice indicates that flaxseeds may boost metabolism. This is probably because they contain good amounts of fiber and protein, along with essential omega-3 fats, antioxidants , and other essential nutrients.

This process aids metabolic health, and it may protect against obesity. Studies suggest that flaxseeds and their nutrients may also help treat or protect against:.

Lentils are another functional food that may reduce the effects of metabolic syndrome. A review of 41 animal studies reports that eating lentils and other legumes, such as beans and peas, can play a central role in preventing and treating metabolic syndrome.

Lentils may also increase metabolism because they are rich in protein. They also contain good amounts of fiber to feed beneficial bacteria in the gut.

Spicy meals that contain fresh or dried chili peppers can increase metabolism and a feeling of fullness. A compound in peppers, called capsaicin, is responsible for these health benefits and more. A study reports that eating capsaicin boosts metabolic rate modestly.

The research also suggests that the compound can contribute to weight management in other ways by increasing the speed at which the body burns fat and reducing appetite. This builds on existing research , published in , which indicates that capsaicin helps the body to burn approximately 50 extra calories each day.

Capsaicin may also reduce pain and inflammation , act as an anticancer agent, and provide antioxidant benefits. Adding ginger to meals could increase body temperature and metabolic rate, and help control appetite.

Ginger also has anti-inflammatory properties, and it may help to reduce nausea during pregnancy and after chemotherapy treatment. Green tea has received plenty of attention in recent years as researchers have shed light on its potential health benefits.

Several studies suggest that green tea extract GTE may increase fat metabolism both at rest and during exercise. However, other research reports no notable effects. Furthermore, scientists cannot guarantee that drinking green tea would have the same results as taking GTE.

A small-scale study involving 63 people with type 2 diabetes suggests that drinking 4 cups of green tea daily can significantly reduce body weight, body mass index BMI , waist size, and systolic blood pressure. Other proposed health benefits of green tea include:.

Coffee can stimulate metabolism thanks to its caffeine content. Research reports that caffeine intake has a stimulating effect on energy expenditure and can lead to increased metabolism.

However, it is essential to be mindful of total consumption. Learn about how much caffeine is too much, here. Decaffeinated coffee does not have the same metabolism boosting benefits.

Brazil nuts are one of the richest sources of selenium , a mineral that is essential for metabolism, reproduction, and immune function. They also contain protein and healthful fats to make people feel fuller.

Selenium is especially important for the thyroid gland, a gland that regulates metabolic function and produces several vital hormones. According to the National Institutes of Health NIH , each Brazil nut provides 68 to 91 micrograms mcg of selenium, which is more than the recommended dietary allowance RDA of 55 mcg per day.

People should avoid eating too many nuts, however, as this can cause selenium toxicity. The NIH set upper limits of selenium intake at mcg. Research also suggests that Brazil nuts can improve the cholesterol levels of healthy people. Abnormal cholesterol levels are a marker of metabolic syndrome.

Broccoli and other cruciferous vegetables may also prevent or slow down several forms of cancer. For more significant metabolism enhancing effects, look for Beneforte broccoli, which contains high levels of glucoraphanin.

Spinach, kale , and other leafy green vegetables may boost metabolism thanks to their iron content. Iron is an essential mineral for metabolism, growth, and development.

Leafy greens are a source of non-heme, or non-animal, iron. Many leafy greens also provide good amounts of magnesium , another mineral that supports metabolic function and plays a role in over processes in the body. Eating a healthful diet is essential for regulating metabolism.

Other ways to boost metabolic function include:. According to one small-scale study , drinking an extra 1, milliliters ml of water daily can decrease body weight and BMI in some people who are overweight. Participants drank ml before each meal. The researchers suggest that this is due to water-induced thermogenesis, where water increases metabolism.

Research suggests that a lack of sleep may be contributing to the trend of increasing obesity and diabetes, which are consequences of metabolic syndrome. According to the CDC , adults should aim to sleep for 7 to 9 hours a night. To improve sleep patterns, try to go to bed and get up at the same time each day.

Lifting weights regularly allows people to gain and retain muscle mass and to burn fat. The Physical Activity Guidelines for Americans recommend that adults should perform strengthening exercises 2 or more days each week. A study on sedentary women found that resistance training increased the overall basal metabolic rate BMR for up to 48 hours.

BMR refers to the number of calories that the body burns while resting. Many foods, including green vegetables, chili peppers, and protein sources, can boost metabolism and help people achieve or maintain a healthy weight.

Other lifestyle changes that improve metabolic health include drinking enough water, getting adequate sleep, and exercise activities. The Everlywell Metabolism Test measures the levels of cortisol, thyroid stimulating hormone, and free testosterone in the body.
