When you google "weight loss" the challenge to sort fact from fiction begins.
Matcha green tea powder claims to speed up weight loss, but let's see what the evidence says.
Matcha is a green tea made from leaves of the Camellia sinensis, or tea plant, but it's processed into a green powder and can be mixed into liquids or food.
Before the leaves are harvested, the tea plant is put in the shade for a few weeks, which increases the content of theanine and caffeine.
No studies have tested the effect of matcha on weight loss. A review of six studies using green tea preparations for weight loss over 12 weeks found a difference based on country. In studies conducted outside of Japan, people consuming green tea did not lose more weight than controls.
In the eight studies conducted within Japan, the mean weight loss ranged from 200 grams to 3.5 kilos in favour of green tea preparations.
Verdict: Fiction! There are currently no studies testing whether matcha tea accelerates weight loss.
