Fat Burner 

Fat burners are supplements that are marketed as a way to increase the rate at which the body burns fat. They are often used by people who are trying to lose weight.

Fat burners may contain a variety of ingredients, including caffeine, green tea extract, conjugated linoleic acid (CLA), and acetyl-L-carnitine. These ingredients are thought to work by increasing the body's metabolism, decreasing appetite, or increasing fat breakdown. However, the effectiveness of fat burners is not well established, and they may not provide significant weight loss benefits.
