Hello, according to your description, I have never heard of the saying that patting your stomach can lose weight, but you can try. Knocking on the stomach meridian every day can effectively lose weight. Shu Tian in the abdomen can harmonize the stomach, eliminate phlegm and eliminate dampness. Rubbing your stomach every day can keep it from swelling. Knock on the belly under the ribs often, and every time 10~ 15 minutes, you will lose weight.
