It is to implant the protein magnetized thread into the corresponding acupoints with thread embedding equipment, and to achieve the purpose of losing weight by continuously and effectively stimulating the acupoints through the thread body (the thread is naturally dissolved and absorbed 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. Catgut embedding to lose weight is a fair and effective dialectical choice based on individual differences, symptoms and obesity mechanisms of patients. Protein magnetized thread (thread instead of needle) is embedded in corresponding acupoints to achieve the functions of invigorating spleen and qi, dredging meridians, harmonizing yin and yang, qi and blood, thus regulating the autonomic nerve and endocrine function of patients.
