Raspberry ketone is a natural phenolic compound that is the primary aroma compound of red raspberries.According to Planta Medica study, it's also a potent fat burner.
Tested on a group of lab mice, it was discovered that raspberry ketone increased both the expression and secretion of adiponectin.
This is important because adiponectin is a protein hormone which modulates a number of metabolic processes, including glucose regulation and fatty acid catabolism. Past research into adiponectin has shown that your levels of adiponectin are inversely correlated with your body fat percentage
Higher adiponectin = lower levels of body fat.
During this latest study, this theory was re-affirmed as the formerly fat lab mice melted off body-fat.As a result of all of this, the researchers concluded that Raspberry Ketone "holds great promise as an fat-burning, health-improving herbal medicine."
