Hydroxycitrate (HCA) is an active ingredient that is extracted from the rind of the Indian fruit, Garcinia cambogia, which is available as an herbal supplement and promoted as a weight loss agent. Chronic administration of Hydroxycitric promotes lipid oxidation and spares carbohydrate utilization in mice at rest and during running. Garcinia cambogia extract, by itself, is unlikely to lead to weight loss, but in combination with other nutrients and herbs it may have potential. Garcinia is sometimes used in combination with other herbs as part of an herbal weight loss product, especially in combination with Green-Tea-Extract or another herb called hoodia extract.

Weight Loss options to consider
5-HTP is a nutrient that helps curb appetite in some individuals. 5-HTP, by converting into serotonin, can be used temporarily to improve will power and decrease the urge to eat until more established weight loss habits are in place. You can buy 5-HTP here.
Hoodia is a cactus plant extract from the Kalahari desert in South Africa that has been getting a lot of attention lately. You can buy Hoodia Extract here.
Green tea extract may be effective in some people as a weight loss pill. You can purchase Green-Tea-Extract here.
Caffeine is often found in weight loss pills but I personally don't like my patients taking extra caffeine since it can cause increased heart rate and anxiety. Most people already consume enough caffeine through coffee, tea, sodas, and chocolate.
Ginger may be helpful in some people but higher doses are required.
Alpha lipoic acid may also reduce appetite but it is primarily used as an antioxidant.
Guarana may work in combination with yerba mate and damiana
Acetyl-l-carnitine is a weight loss pill that may reduce appetite in some individuals. You can buy Acetyl-l-Carnitine here.

Garcinia cambogia extract study
Garcinia cambogia is able to decrease the acidity and to increase the mucosal defense in the gastric areas, thereby justifying its use as an anti-ulcerogenic agent.

Garcinia cambogia extract was isolated from the fruit of the Garcinia cambogia and was used as a potential antiobesity agent. In week 3 of culture with insulin, the fat cells exhibited more numerous and larger intracytoplasmic lipid droplets (i.e. 30-40 microm(2)). When Garcinia cambogia extract and insulin were added simultaneously, the accumulation of lipid droplets was inhibited and the peak droplet area shifted to become smaller (10-20 microm(2)). The activities of glycerophosphate dehydrogenase, a marker of adipose differentiation, were not significantly inhibited by the Garcinia extract. These findings suggest that the Garcinia cambogia extract inhibits lipid droplet accumulation in fat cells without affecting adipose conversion.

1998 Garcinia cambogia extract study in JAMA
Hydroxycitric acid, the active ingredient in the herbal compound Garcinia cambogia, competitively inhibits the extramitochondrial enzyme adenosine triphosphate-citrate (pro-3S)-lyase. As a citrate cleavage enzyme that may play an essential role in de novo lipogenesis inhibition, G cambogia is claimed to lower body weight and reduce fat mass in humans. To evaluate the efficacy of Garcinia for body weight and fat mass loss in overweight human subjects. Twelve-week randomized, double-blind, placebo-controlled trial. Overweight men and women subjects (mean body mass index [weight in kilograms divided by the square of height in meters], approximately 32 kg/m2). Subjects were randomized to receive either active herbal compound (1500 mg of hydroxycitric acid per day) or placebo, and both groups were prescribed a high-fiber, low-energy diet. The treatment period was 12 weeks. Garcinia cambogia failed to produce significant weight loss and fat mass loss beyond that observed with placebo.

Effects of (-)-hydroxycitric acid on appetitive variables.

(-)-Hydroxycitric acid (HCA) reportedly promotes weight loss, in part, through suppression of hunger. However, this mechanism has never been evaluated in humans in a controlled study. Eighty-nine mildly overweight females were prescribed 5020-kJ diets for 12 weeks as part of a double-blind, placebo-controlled parallel group study. Forty-two participants ingested 400-mg caplets of Garcinia cambogia 30-60 min prior to meals for a total dose of 2.4 g/day (1.2 g/day HCA). Forty-seven participants ingested matched placebos. Weight and body composition were assessed at baseline and every other week for 12 weeks. Food intake and appetitive variables were assessed at baseline and monthly for 12 weeks. Both groups lost body weight with the active group achieving a significantly greater reduction. No effects of the HCA were observed on appetitive variables. The active treatment group did not exhibit better dietary compliance or significant correlations between appetitive variables and energy intake or weight change. This study does not support a satiety effect of HCA.

The treatment period was 12 weeks. Body weight was evaluated every other week and fat mass was measured at weeks 0 and 12. Body weight change and fat mass change. A total of 135 subjects were randomized to either active hydroxycitric acid or placebo ; 42 (64%) in the active hydroxycitric acid group and 42 (61%) in the placebo group completed 12 weeks of treatment. Patients in both groups lost a significant amount of weight during the 12-week treatment period; however, between-group weight loss differences were not statistically significant. There were no significant differences in estimated percentage of body fat mass loss between treatment groups, and the fraction of subject weight loss as fat was not influenced by treatment group. Garcinia cambogia failed to produce significant weight loss and fat mass loss beyond that observed with placebo.
