Dr. Oz recently called Garcinia Cambogia Extract (GCA) the Holy Grail of Weight Loss. Good thing we've had it in our Fat Fighters for years... what does GCA do? It acts as a Fat Blocker, Appetite Suppressant and Controls Cravings. Helps Decrease Belly Fat. Emotional Eaters will see an increase in Serotonin which will balance moods. It helps in managing Cortisol (the stress hormone) .
