Raspberry Ketones is a compound found in raspberries, they aid in metabolism and in turn weight loss or fat burning by increasing the presence of a protein in the blood stream called Adiponectin. This protein helps to regulate the metabolism particularly that of the fatty acids contained in fat cells. The higher the presence of adiponectin in the blood stream, the more adequately the body's metabolism is able to break down the fat within its cells in order for it to be used as energy.
