With a caffeine count higher than coffee, these teas kick your metabolism into gear. In a study published in the journal Physiology & Behavior, a 3-4 percent increase in metabolic rate was measured in both lean and obese subjects after a single 100 mg dose of caffeine. Look for teas made from this caffeine-containing fruit; if you want to skip comparative shopping, just grab a box of Celestial Seasonings’ Fast Lane, which clocks in 20 mg above your daily cup of coffee at 110 mg caffeine.
Green tea is obtained from the apical leaves of the plant Camellia sinensis. It contains a good amount of catechins, specifically epigallocatechin gallate (EGCG), and caffeine (less than coffee). EGCG and caffeine are both responsible for its weight loss properties. EGCG, an antioxidant, helps scavenge the harmful oxygen radicals, thereby reducing inflammation and inflammation-induced obesity and hence placing it high on the list of best teas for weight loss. Various studies by researchers proved that consuming green tea could help obese and diabetic patients lose weight by increasing fat metabolism and satiety and suppressing obesity genes (5), (6), (7).
