Catgut embedding to lose weight is an extension and development of acupuncture weight loss, and it is an improved external moxibustion. It is to implant protein magnetized silk into corresponding acupoints with a silk embedding device, and to achieve the purpose of losing weight by continuously and effectively stimulating acupoints through the silk body (silk naturally dissolves and absorbs in the body 15 days to 3 months). This method embeds the thread 1 time in 15 days, which avoids the trouble and pain of "acupuncture" once a day for obese patients and is the first choice for busy modern people to lose weight.
