Can anyone tell me exactly how EGCG helps with weightloss? I don’t quite understand and have had trouble finding non biased sources.
Here’s a study I found. Unable to find the original source. This is a cut and paste job for a nutritional forum I frequent.

This study evaluated the influence of a green tea catechin beverage on body composition and fat distribution in overweight and obese adults during exercise-induced weight loss. Participants (n = 132 with 107 completers) were randomly assigned to receive a beverage containing 625 mg of catechins with 39 mg caffeine or a control beverage (39 mg caffeine, no catechins) for 12 wk. Participants were asked to maintain constant energy intake and engage in 180 min/wk moderate intensity exercise, including 3 supervised sessions per week. Body composition (dual X-ray absorptiometry), abdominal fat areas (computed tomography), and clinical laboratory tests were measured at baseline and wk 12. There was a trend (P = 0.079) toward greater loss of body weight in the catechin group compared with the control group; least squares mean (95% CI) changes, adjusted for baseline value, age, and sex, were ?2.2 (?3.1, ?1.3) and ?1.0 (?1.9, ?0.1) kg, respectively. Percentage changes in fat mass did not differ between the catechin [5.2 (?7.0, ?3.4)] and control groups [?3.5 (?5.4, 1.6)] (P = 0.208). However, percentage changes in total abdominal fat area [?7.7 (?11.7, ?3.8) vs. ?0.3 (?4.4, 3.9); P = 0.013], subcutaneous abdominal fat area [?6.2 (?10.2, ?2.2) vs. 0.8 (?3.3, 4.9); P = 0.019], and fasting serum triglycerides (TG) [?11.2 (?18.8, ?3.6) vs. 1.9 (?5.9, 9.7); P = 0.023] were greater in the catechin group. These findings suggest that green tea catechin consumption enhances exercise-induced changes in abdominal fat and serum TG."
I drink a ton of the stuff. I can’t really say for sure whether or not it’s helped with fatloss, but I drink it for all the health benefits it provides.
Thanks for the study, but I’m more wondering how it interacts with the body to induce weight loss. I’m taking green tea pills at the moment.
