Abstract
Background
Obesity is an energy balance problem caused by overeating. Obesity treatment includes diet, exercise, behaviour treatment, pharmacotherapy and surgery; in addition, acupuncture is also an option.
Objective
To investigate the effect of acupuncture on weight loss and whether a brief acupuncture treatment of 5 weeks can change circulating levels of leptin, ghrelin, insulin and cholecystokinin (CCK) in obese women.
Methods
40 women with a body mass index (BMI)>30 kg/m2 were equally randomised to either an acupuncture group or a sham (non-penetrating) acupuncture group and received treatment at LI4, HT7, ST36, ST44 and SP6 bilaterally. Both groups had two sessions of 20 min/week for a total of 10 sessions. Serum insulin, leptin, plasma ghrelin and CCK levels were measured by ELISA.
Results
Acupuncture treatment decreased insulin and leptin levels and induced weight loss, together with a decrease in BMI compared with sham acupuncture. Furthermore, between-group analyses demonstrated increases in plasma ghrelin and CCK levels in subjects who received acupuncture treatment.
Conclusion
These findings suggest that acupuncture may help to regulate weight owing to its beneficial effects on hormones such as insulin, leptin, ghrelin and CCK in obese subjects even after a few weeks of treatment.
