One hour after meals is the best time to drink green tea to lose weight.

It is often said that drinking tea before meals is good for losing weight, because drinking tea before meals can suppress appetite. However, in fact, because tea contains a lot of tannic acid, it will greatly stimulate the gastric mucosa, cause gastric dysfunction, lead to indigestion, and also stimulate the intestinal mucosa, thus hindering the intestinal absorption of nutrients. In addition, theophylline in tea will inhibit the absorption of iron by small intestine. Therefore, in general, drinking tea before meals is actually unfavorable to lose weight.

And drinking a cup of green tea one hour after meals can scrape off oil, promote digestion and prevent fat accumulation.
