"When we think about managing our weight what we eat may jump into our minds first, followed by the need to exercise. However, what we drink has its own role to play too. For green tea, in particular, there seems to be a growing evidence-base around its potential weight loss benefits and ability to reduce fat mass.
“We look to randomised controlled trials (RCT) as the 'gold standard' when it comes to the quality of scientific evidence. So, I read with interest a new RCT1 looking at the effects of green tea extract - 857mg epigallocatechin gallate taken daily by 115 women with central obesity over 12 weeks. Findings were positive with significant reductions in weight and body mass index being observed. Most interesting of all, reductions in ghrelin and rises in adiponectin levels were seen. These are appetite hormones, indicating that green tea extract may have a role in modulating these.
"Clearly further studies are needed, using green tea extract in beverage form. That said, when it comes to regulating weight, there is no one-stop miracle. A calorie-controlled diet, combined with portion size control, physical activity and healthy hydration habits, which include drinking (green) tea may all have their collative roles to play."
