The principle of scraping is based on the the twelve meridians and the eight strange meridians in traditional Chinese medicine, following the principle of "treating symptoms to relieve emergency", and strongly stimulating the meridians by means of manipulation, so as to make the local skin red and congested, thus achieving the effects of waking up, removing toxic substances and pathogens, clearing away heat and relieving exterior syndrome, promoting qi circulation and relieving pain, strengthening the spleen and regulating the stomach. For weight loss, scraping is irrelevant. Fat accumulates under the subcutaneous nerve. Diet and exercise are the best ways to lose weight. Exercise must be persisted, with strenuous exercise for more than 30 minutes or basic exercise 1 hour every day, so as to consume fat. Be sure to stick to it, and the effect will be achieved in three months. Jogging is best, and the heart and lungs contract at the same time. Eat normally and don't overeat. Eat more fruits. Eat lean meat and eat less snacks. In addition, rest regularly, because in the process of losing weight, you should be energetic. This method is very common, but it is very effective. You can try.
