A Japanese study found evidence that beverages containing high amounts of catechin, a flavonoid found in green tea, may aid in preventing obesity. [173] Patients in the investigation, all of whom had type 2 diabetes mellitus, ingested either 582.8 mg or 96.3 mg of catechins per day by drinking green tea. By the 12th week, participants receiving the higher catechin dose had undergone a significantly greater reduction in waist circumference than did patients receiving the lower dose.
