Dear Alice, I have just received an envelope containing advertising for a weight-loss product containing hydroxy citric acid. Obviously, this is not all fat. It's derived primarily from the Garcinia cambogia plant.
Citric acid is a substance involved in the metabolism of carbohydrates.
It is suggested that, in the presence of HCA, excess carbohydrates would be expended instead of being stored as fat. A decrease in appetite is purported to be a side effect of this process, which further promotes weight loss. This certainly sounds good in theory. This is because their preliminary tests led to testicular atrophy and other toxicities in lab animals. Whether the same results occur in humans remains unknown.
