Re: HCA (hydroxycitric acid) for suppressingappetite?

[Guest guest]

This is all internet derived info:

" HCA(hydroxycitric acid) is obtained as a 50% standardized extract of

Garcinia cambogia, a small fruit from southern India, where it has been used

for centuries as a food preservative, flavoring agent and digestive aid. HCA

is a close relative of citric acid, the agent that gives citrus fruits their

characteristic tart flavor. "

" HCA, or hydroxycitric acid, is an herbal extract sometimes found in

non-prescription diet pills. HCA supposedly suppresses the appetite and

slows down the conversion of carbohydrates into fat.

However, in a 1998 study published in the Journal of the American Medical

Association, researchers from Columbia University gave HCA herbal diet

supplements (1,500 milligrams per day) to 66 overweight patients. Result?

HCA failed to produce significant weight loss "

Also, here's a study that does NOT support the appetite suppression effect

of HCA:

" Physiol Behav. 2000 Oct 1-15;71(1-2):87-94. Links

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 (3. 7+/-3.1 kg versus 2.4+/-2.9 kg). 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.

I get mine from Beyond-A-Century.com. At least it's relatively inexpensive,

and presumably harmless, if worthless as an appetite suppressant, weight

loss aid, and moderator of insulinemic and blood glucose response to

carbohydrates!
