Low concentration of Malonyl Coenzyme A increases the rate of which oxidation of fat in both adipose and liver tissue. HCA also increases ketone production and slows the breakdown of muscle tissue while in a hypocaloric diet. By keeping more muscle, the body will burn more fat. The greater the lean mass you have the faster the metabolic rate , which translates to less calorie restriction in periods of dieting. The effect of HCA on reduced fat, namely visceral, had no rebound effect after a month of ending usage. HCA also increases serotonin levels.
