Fat burners are supplements intended to help a person lose weight or maintain an existing weight. A review by Jeukendrup (2011) found fat burners typically made claims like:
- increasing fat metabolism
- increasing energy expenditure
- impairing fat absorption
- increasing weight loss
- increasing fat oxidation during exercise, or
- somehow promote changes that increase fat metabolism.

- Conjugated linoleic acid (CLA)
- Epigallocatechin‐3‐gallate (EGCG)

Theory[edit | edit source]
Evidence[edit | edit source]
Many supplements marketed as "fat burners" or for "weight management" make exaggerated or unproven claims about weight loss, typically claiming to increase energy metabolism. This is not the same as giving a feeling of energy - so-called fat burners supplements increase the body's requirements for energy.
