There is no over the counter supplement that will help you lose weight or inches. If there were, we wouldn't need Sparkpeople, and we'd all be taking it. :)
The fact of the matter is, these things don't do what they claim to do. They can't. They don't have to tell you the truth, because most of them are unregulated by the FDA.
A quick google search tells me this is another one of Dr. Oz's corporate shills. Just like green coffee bean, raspberry ketones, or whatever supplement he's selling next, he'll take something that's had one preliminary rat study with somewhat promising results, and claim it's the "holy grail" of weight loss.
Studies have shown no real statistically significant differences from placebo. jama.jamanetwork.com/article.aspx?articlei
"The present study, carried out during a 12-week evaluation period and using accepted experimental design and in vivo analytic methods, failed to support the hypothesis that hydroxycitric acid as prescribed promotes either additional weight or fat mass loss beyond that observed with placebo. Specifically, body weight and fat mass change during the 12-week study period did not differ significantly between placebo and treatment groups. These results apply to both the primary and secondary statistical analyses. Additionally, there were no observed selective fat-mobilizing effects specifically attributable to the active agent, hydroxycitric acid."
In other words, there is no evidence whatsoever that the effects people are having with this drug are attributable to the drug itself and not their own lifestyles.
