Obesity is the condition that excess fat stored in the body. Nowadays, the prevalence of obesity has greatly increased due to westernized dietary habits and changes in lifestyle. It has been proved that obesity is a risk factor of many diseases. Many methods were developed to find curative means for obesity and exercise and controlling diet were considered very effective ones. In order to find the theraputic effect of the exercise and food diary, we examined patients treated by electric accupuncture and ear accupuncture because of obesity. We observed 16 patients with obesity who visited KyungHee Univ., Kangnam Hospital of Oriental Medicine from November, 2002 to March, 2003. To rule out an bias, we excluded the patients who were treated for other disease or took medicine. Exercise in hospital was not effective for treatment of obesity, but keeping diary of diet was effcetive for the decrease of body weight(p<0.05).
