It has been shown to inhibit an important enzyme found in the liver which is needed to break down glycogen: glucose-6-phosphatase (G6P). Now this has Java  Burn been shown in the lab[2], but not yet in a living animal, so how do we know it actually does inhibit G6P when eaten? Well it has not been directly demonstrated, but scientists have shown that chlorogenic acid is absorbed into the blood, via the stomach without getting degraded in rats[3]. So it is reasonable to assume that it arrives at the liver intact, where is can get to work inhibiting G6P.
