Dr+Oz's+Magic+Weight+Loss+Compound

Green tea extract, which Dr. Mehmet Oz promoted on his show as a "magic weight-loss cure," had one scientific study backing up the extract's purported effects. Now, that research has been retracted, the blog reported.
 * Intro **

**Claims**

When asked specifically about the green coffee bean extract, Oz cited a study that found people who took the supplements did lose weight.


 * Evidence **

"A randomized placebo-controlled double blind parallel trial in 76 overweight and moderately obese subjects, (BMI, 27.5 ± 2.7 kg/m 2 ) matched for sex, age, BMI, height, body mass, and habitual caffeine intake was conducted. A very low energy diet intervention during 4 weeks was followed by 3 months of weight maintenance (WM); during the WM period, the subjects received a green tea-caffeine mixture (270 mg epigallocatechin gallate + 150 mg caffeine per day) or placebo."

**Results** "Subjects lost 5.9 ±1.8 (SD) kg (7.0 ± 2.1%) of body weight ( //p // < 0.001). At baseline, satiety was positively, and in women, leptin was inversely, related to subjects’ habitual caffeine consumption ( //p // < 0.01). High caffeine consumers reduced weight, fat mass, and waist circumference more than low caffeine consumers; resting energy expenditure was reduced less and respiratory quotient was reduced more during weight loss ( //p // < 0.01). In the low caffeine consumers, during WM, green tea still reduced body weight, waist, respiratory quotient and body fat, whereas resting energy expenditure was increased compared with a restoration of these variables with placebo ( //<span style="color: #333333; font-family: 'Open Sans',Arial,Helvetica,'Lucida Sans Unicode',sans-serif; font-size: 16px; vertical-align: baseline;">p //<span style="background-color: #f9f9f9; color: #333333; font-family: 'Open Sans',Arial,Helvetica,'Lucida Sans Unicode',sans-serif; font-size: 16px;"> < 0.01). In the high caffeine consumers, no effects of the green tea-caffeine mixture were observed during WM."
