However, some people especially like yogurt, and drinking a lot of yogurt after meals often may lead to weight gain. This is because yogurt itself contains a certain amount of calories, and drinking yogurt after meals is equivalent to ingesting these calories, which leads to weight gain.

It is best to drink it half an hour to an hour after meals, which can regulate intestinal flora and is beneficial to health.
