Looks good. Doesn't necessarily do you good.

Looks good. Doesn’t necessarily do you good.

There are a vast number of online ads currently pushing the Garcinia Cambogia diet, claiming it to be a wonder for weight loss, because it contains HCA, a kind of citric acid, which is claimed in a million breathless online ads (and elsewhere) to produce weight loss.

Sadly, before you part with your $49.95, be aware that the brouhahaha is just that – a load of marketing froth and bubble.

And it could even harm you.

Here’s the relevant Wikipedia extracts:

Hydroxycitric acid (HCA) is a derivative of citric acid that is found in a variety of tropical plants including Garcinia cambogia and Hibiscus subdariffa.

Biological effects

Laboratory and animal studies of HCA have produced results that indicate a potential for modulation of lipid metabolism. However, a clinical study has demonstrated that HCA has no effect in terms of weight loss or reduction of fat mass. A 1998 randomised controlled trial looked at the effects of hydroxycitric acid, the purported active component in Garcinia gummi-gutta, as a potential anti-obesity agent in 135 people. The conclusion from this trial was that “Garcinia cambogia failed to produce significant weight loss and fat mass loss beyond that observed with placebo”.

And a meta-analysis published in 2010 revealed that gastrointestinal adverse effects were twice as likely for users of hydroxycitric acid.

One HCA product had to be withdrawn because of liver toxicity.

In a study in Zucker rats, which are genetically predisposed to obesity, Garcinia cambogia extract containing HCA showed that high doses led to significant suppression of epididymal fat accumulation, but also had high testicular toxicity. However, this study has been criticised because of possible contamination of the HCA used and various design flaws.

Like all things, peeps, there IS no short cut to weight loss. The solution? Walk more, eat less. Er, that’s it.
