Thermogenic fat burners are one of the most popular categories of dietary supplements promoted for weight control and body fat reduction.

The term “fat burner” is primarily a marketing term and does not imply that a supplement can directly dissolve or remove stored fat. In practice, thermogenic supplements contain ingredients that may temporarily increase energy expenditure, thermogenesis, fatty acid oxidation, or feelings of alertness.

Some ingredients may also affect appetite or performance during exercise. However, their overall effect on weight loss is usually small and depends on diet, physical activity, sleep, duration of use, and individual characteristics.

Formal reviews of weight loss supplements note that the scientific evidence varies considerably between ingredients. Many studies are small, short-term, or examine combinations of multiple substances, making it difficult to determine the true contribution of each component.
