Which substances are there in fat burners?

1. Fat burners and body sculptors should ensure that your fat burning increases. But what is actually in these products? An overview: 8 common substances in fat burners.

1. Caffeine

1. Caffeine is an extract from coffee beans, but it is also found in tea leaves and chocolate. The intake of caffeine supplements should not be equated with drinking a cup of coffee or tea, certainly not from a health point of view: coffee and tea contain many other flavoring and active substances in addition to caffeine. A Caffeine has long been of interest for its effects on metabolism. Initially it was thought that the substance stimulates fat burning during sports activities and saves sugar reserves. There are indeed indications in that direction, but it is doubtful whether this will yield anything in practice. Caffeine is more likely to make the brain slightly less sensitive to signals of fatigue. The effect on the metabolism is not strong enough for significant weight loss. A

2. Green teaÂ

1. Green tea and oolong (white tea) are high in catechins that some sources say are said to stimulate fat metabolism. Indeed, there is some evidence that green tea helps a little bit for weight loss, but the studies contradict each other. The effect would be stronger in people who normally take little or no caffeine, and also greater in people of Asian and European descent. High doses of epigallocatechin-3-gallate (EGCG), a specific catechin in green tea, have been shown to increase fat burning during exercise by about 20 percent, according to only two studies. But that does not mean that EGCG helps with weight loss. A

3. CarnitineÂ

1. Carnitine, a substance that the body produces itself, but which also gets it from meat, plays a central role in fat metabolism. It is, as it were, the starting key for the transport belt of fats to the mitochondria (the power plants of all cells). Carnitine stimulates fat burning and is said to save sugar reserves during endurance efforts. A But the body has more than enough carnitine to keep the metabolism running at full speed at rest and with light exertion. In that case, extra carnitine yields nothing. Moreover, there is no hard evidence that carnitine stimulates fat burning, and to increase the concentration of carnitine in the muscles, you should combine the intake with sugar, but that is not the intention. So rejected. A

4. KelpÂ

1. Kelp, a brown seaweed species (Undaria pinnatifida), contains fucoxanthin, a substance that is said to boost fat metabolism. Animals lost considerable weight in four weeks, but at a dose that would correspond to 280 grams per day for a human weighing 70 kilos. Unrealistically high. In the only human trial, an additional weight loss of 5 kilos was achieved compared to a placebo group, and that with a dose of 2.4 milligrams. But the study was conducted by the company that has patents on fucoxanthin. That makes the results less reliable. In any case, one study is not enough to draw conclusions. So it has not been proven that kelp contributes to weight loss. A

5. ChromeÂ

1. Everyone needs chromium, but small amounts are sufficient. It is found in mushrooms, wheat germ and brewer's yeast. According to some sources, many people do not consume enough chromium, but there are also quite a few doubts about this. Chromium is said to build muscle, burn fat and block the urge for sweetness. It is usually presented in the form of chromium picolinate or nicotinate. A One old study did indeed find an increase in muscle mass, but that happened on the basis of unreliable measurements. Four more recent studies with sophisticated measurement techniques showed no effect on muscle mass or fat burning. In addition, there are indications that chromium picolinate contains the DNA can be damaged, and that's a good reason not to use it. A

6. Conjugated Linolenic Acid

1. Conjugated linolenic acids belong to the group of omega 6 fatty acids. Research in humans is inconclusive, even though it appears that there is a weight loss of 50 grams per week in the long term. But even that is not certain. A

7. TaurineÂ

1. Two years ago, participants in a cycling test were found to burn 16 percent more fat after taking taurine. Helpful vendors crowed, but a closer reading of this research raises doubts. According to two other studies, taurine has no effect on fat metabolism. We don't know more yet. A

8. Hot pepper

1. Capsaicin is the spicy substance in peppers and peppers that gives dishes extra spice. The substance appears to affect the weight of people who consume it regularly and in significant amounts, but few Westerners can maintain that.
