Raspberry ketones are the compounds that give red raspberries their characteristic flavor. In the fruit itself, flavor is their function. When introduced into the human body, however, raspberry ketones encourage the metabolism (or burning) of fat. Raspberry ketones can also help maintain consistent and jitter-free energy, even when on a reduced-calorie diet.
