Fat burners are nutritional supplements that are designed to help burn fat and increase metabolism. They work by increasing the breakdown of fatty acids in adipose tissue, which are then released into the bloodstream and used for energy. Caffeine is the main ingredient in most fat burners, and it helps to lose weight by increasing metabolism and helping the body use fat for fuel. In addition, some herbs, such as ephedra, can also be used to burn fat, but they can cause high blood pressure, mood changes, irregular heart rate, strokes, seizures and heart attacks.
A study published in the American Journal of Clinical Nutrition found that men who ingested the active ingredient in green tea (catechins) significantly reduced total fat area, waist circumference, thickness of skin folds and subcutaneous fat area. The ingredients in fat burners also improve endurance, alertness, memory, a sense of stamina and reduce fatigue. The answer to whether a fat burner can make you gain weight is that it depends on how you use it. If you take a strong appetite suppressant as part of your fat burner regimen, you may be more likely to gain weight if you eat more calories than you consume.
On the other hand, if you take a reasonable approach to your overall nutrition and monitor your stimulant intake, fat burners can be a sure way to increase your results. It's important to note that if you stop using a stimulant abruptly, your metabolism may slow down and you may gain weight as you recover your normal metabolic rate. To avoid this, it's recommended that you stop using your fat burner from time to time so that it still helps you lose belly fat. Finally, it's important to remember that the Food and Drug Administration (FDA) does not regulate or approve products such as fat burners before they go on the market.
Therefore, excessive intake of fat burners can cause liver damage, fluctuations in blood pressure, anxiety, headaches, heart attack, insomnia and nausea.
