ABSTRACT
The effects of auricular acupuncture stimulation on non-obese healthy volunteers were tested. Subjects (n=35) averaged 31.5 (17-57) years old, and average BMI was 25.3 (19.2-35.7) kg/m<sup>2</sup>. Small (2.0×0.15mm) auricular needles were applied intracutaneously into the bilateral cavum conchae, a vagally (Arnold n.) innervated region that was identified by having low resistance (27.1-345.5kΩ/cm<sup>2</sup>), for six weeks. Body weight was measured four times a day, and was charted by the subjects themselves.<br>Results showed that, in the period of without auricular stimulation, only body weight was measured and charted, 31.4% of the subjects reduced their body weight. In the auricular acupuncture treated period, 19 out of 27 subjects (70.4%) decreased (p<0.01), 4 (14.8%) increased, and4 (14.8%) had no change in their body weights.<br>In conclusion, the results suggest that success in maintaining weight reduction can be attributed to graphic illustration of ones weight pattern. Bilateral auricular acupuncture stimulation can also reduced the body weight of healthy non-obese subjects. This is consistent with the suggestion that daily charting of body weight and auricular acupuncture might be effective in the treatment of obese patients.
