What is raspberry ketone?
Ketones are a natural phenolic compound that impart the flavor and aroma to red raspberries. Besides it's use as a weight loss aid, it is extensively used in the food and beverages industry as flavoring. Because it is found in very small quantities, it is rather expensive and a kilogram of pure raspberry ketone can cost upto $20,000. In the late 1960's, raspberry ketone was recognized by the FDA a safe to consume.
Raspberry Ketone is now widely used as a supplement to lose weight. When tested on laboratory mice, it was found to prevent weight gain that's caused by a high fat diet.
