In this study, a 8-week, single blinded, randomized controlled clinical trial will be conducted to examine the efficacy and safety of body acupuncture in the treatment of central obesity in Hong Kong.
This is a pilot single-blind, randomized, sham-controlled trial. 168 central obesity patients will be randomly assigned to acupuncture group or control group. The duration of the treatment will be 8 weeks with 2 session per week and the follow-up period will be 2 weeks.

| Acupuncture group | Experimental | Body electro-acupuncture will be conducted for 2 sessions per week over 8 consecutive weeks. Body electro-acupuncture will choose eight acupoints as Tianshu(ST-25), Daheng(SP-15), Daimai(GB-26), Qihai(CV-6), Zhongwan(CV-12), Zusanli (ST-36), Fenlong(ST-40), Sanyinjiao(SP-6).Disposable acupuncture needles (verum acupuncture needles asia-med Special No. 16 with 0.30 x 0.30mm matching the Streitberger sham-needles) will be inserted at a depth of 10-25 mm into the points. We will also deliver electrical stimulation with dense-disperse waves with 50Hz at 10 volts through electrical acupuncture stimulation instrument (ES-160 6-Channel Programmable Electro-acupuncture) to the abdominal points. The bodily needles will be retained for 30 minutes. |

| sham-acupuncture group | Placebo Comparator | As to the participants allocated to control group, Streitberger's non-invasive acupuncture needles (Gauge 8 x 1.2" / 0.30 x 30 mm) will be applied to act as sham control at the same acupoints with same stimulation modality. However, the needles will be only adhered to the skin instead of insertion. The validity and credibility of this model has been well demonstrated. |

Subjects of both groups will be randomly assigned to receive either electro-acupuncture or control (sham) treatment. For randomization, simple, complete non-sequential random numbers will be generated in advance by a computer program in a block of four, and kept by the principal investigator. After a patient's eligibility is confirmed, a randomization number which corresponds to the group allocation will be provided to the acupuncturist by the PI. This arrangement will ensure that the clinical assessor and participants are blinded to the allocation.

Adverse events of acupuncture treatment will be assessed using the Treatment Emergent Symptom Scale (TESS) and would be evaluated during the whole procedure, as well as laboratory tests (whole blood counts, renal and liver functions) if needed. All clinical adverse events will be recorded in terms of intensity (mild, moderate, or severe), duration, outcome and relationship to the study.
