Besides increasing your metabolism and helping you stay focus, green tea is a great fat burner!
Green tea extract (GTE) helps people lose weight. It is not a magic bullet against obesity but it helps. Scientists speculate that chemicals in the supplement called catechins are the active ingredients that fight fat. One catechin called epigallocatechin-3gallate (EGCG) is particularly effective in promoting thermogenesis (increased calorie use) and speeding weight loss. British researchers found that GTE increased fat use by 17 percent during 30 minutes of aerobic exercise (single dose containing 890 milligrams of polyphenols and 366 milligrams of EGCG). In a second experiment involving blood sugar regulation after consuming a high sugar drink, GTE lowered blood sugar faster than a placebo (fake GTE) with less insulin release.
GTE has other health benefits. It reduces cell death and speeds recovery after a heart attack or stroke. It also contains antioxidants that protect the cells from free radical damage. Free radicals are destructive chemicals produced naturally during metabolism that cause destruction of cell membranes and DNA and promote heart disease, cancer and premature aging. An 11-year study of more than 40,000 Japanese adults found that chronic consumption of green tea reduced death rates from all causes and from cardiovascular disease. GTE looks like an excellent supplement that promotes metabolic health and speeds weight loss. (American Journal Clinical Nutrition, 87: 778-784, 2008; Journal Medicinal Foods, 9: 451-458, 2006)
