Thermogenic supplements contain ingredients that increase our metabolism, so they essentially help us burn more calories. Generally, the more calories you burn, the quicker you lose weight. You can see how thermogenics are connected to weight loss.

Some supplements contain just one thermogenic ingredient, while others will blend a few different ones together to increase weight loss potential. One of the most well-known, commonly-used thermogenic ingredients is caffeine. Caffeine is a stimulant that can be found in more than 60 plants. Many of us consume it regularly through foods and beverages — your coffee, green tea or pre-workout all contain caffeine.

Caffeine increases adrenaline levels in the body. Adrenaline is the hormone responsible for promoting your fat cells to release fatty acids into the bloodstream so that your cells can snatch them up and use them for energy. In other words, caffeine stimulates adrenaline, which increases the amount of energy in your cells.

This in turn increases your metabolic output, so you burn more calories and therefore lose weight. Caffeine is an appetite suppressant , so it also helps to promote weight loss by causing you to eat less.

Consuming just a milligram of caffeine will help you burn an extra 0. So, a mg dose of caffeine would prompt you to burn an extra 15 calories in the day.

Capsaicin is considered purely thermogenic due to its ability to quickly increase heat in the body. There are actually six compounds in the capsaicinoid family, though capsaicin is one of the most potent. Much like caffeine, capsaicin causes the body to release adrenaline, which in turn accelerates your metabolism and promotes fat burning.

It is also an appetite suppressant, so it can cause weight loss by simultaneously burning calories quicker and reducing the number of calories going into your body.

Capsaicin also increases the rate at which your body uses fat as fuel, a process known as fat oxidation. The combination of its oxidative-increasing, metabolic-enhancing, and appetite-suppressing properties makes it a potentially powerful weight loss supplement. Garcinia Cambogia is a tropical pumpkin-shaped fruit that is native to Indonesia.

The rind of the fruit is used in both food and medicines. The extracts of Garcinia Cambogia are added to weight loss supplements because of the hydroxycitric acid HDA content in the fruit. HDA is the primary organic acid in Garcinia Cambogia. This acid essentially interferes with the function of ATP citrate lyase, which is an enzyme in the body responsible for forming fat.

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.

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.
