4.1 Modern Research
4.1.1 Body acupuncture
Obesity is caused by dysfunction of transportation and transformation of the body fluid, accumulation of dampness and phlegm turbidity, which are the result of disorders of Zang-Fu organs, stagnation of Qi and Blood, disharmony of the Thoroughfare and Conception vessels. Obesity achieved by needling meridian points to balance Yin and Yang, regulate Zang-Fu organs, promote flow of Qi and Blood of the meridians, and eliminates the pathogenic factors by dredging meridian and collateral. Needles can be twirled, electrically stimulated and left in place. The filiform needles with diameter of 0.25-0.30mm and length of 40-75mm were typically selected based on the case's obesity degree.
Meng et al. (Zhang, 2008) treated 180 cases of female simple obesity by using electro-acupuncture (EA) and 60 cases by manual acupuncture for controlling obesity. Ren 12, ST 25, Ren 4 and ST 36 were chosen as main points in both groups. In the EA treatment group, bilateral ST 25 was stimulated by electric device with disperse and dense wave and the strength bearable to patients. Needle were retained for 40 min. and the treatment was given 5 times a week followed by a 2 days interval in both group, and 20 sessions made up of a therapeutic course. The total effective rate of 97.8% and 88% was achieved in the EA treatment and control group respectively. Yin (Zhang, 2008) chose Ren 12, Ren 4, and SP 6 as main points, and added secondary points according to differentiation of symptoms and signs. After the arrival of Qi by lifting and thrusting for reinforcing and reducing, electric device was applied to the main points with continuous waves and 20/sec. in frequency and intensity tolerable to patients. The treatment was given once every other day, and 10 treatments made up a therapeutic course with an interval of 3 days between two courses of treatments was 87.5%.
As the function of the EA can be precisely characterized and the results are more or less copied, an attempt was made by Han Jisheng's research team to clarify whether EA of strictly identified parameters is effective to suppress the simple obesity induced by high energy diet in a rat model. In the diet induced obese rats, EA was applied at the posterior leg acupoints 3 times per week for 4 weeks with high energy diet and water provided. A significant reduction of the body weight accompanied by reduction in food intake was observed.
4.1.2 EA acupoint and its Frequency selection
2 Hz EA was more effective than 100 Hz EA (Tian et al., 2005). As its results, diet induced obese rats showed an increased level of plasma cholesterol and triglyceride. EA stimulation produced a reduction of plasma level of total cholesterol and triglyceride. In this respect, 100 Hz EA was more effective than 2 Hz EA. If it is confirmed that 2 Hz EA is more effective in body weight loss and 100 Hz EA more effective in decreasing plasma lipid content, it may be worthwhile to try the 2/100 Hz alternative mode of stimulation to cover both sides of the disorder.

4.1.2 Auricular therapy
In TCM, the ears are an important pivot point for the meridians to communicate with each other. When the organs are in disharmony, it will be reflected on the ear. It produces dramatic body weight reductions in obese patients. It has physiologic and anorexigenic functions must be explained. Fetal somatotop and Nogier's inverted somatotopy have been analyzed. The similarity between the localization of the motor and somatosensory representations of the ear in the cerebral cortex in the fetus has also been noted in both Western and Chinese journals.
