Acupuncture is not a substitute to a healthy diet and exercise, but it is a powerful tool to boost the effects of both. It achieves results mainly through appetite suppression and increasing your metabolism. Acupuncture is widely used in China to lose weight by both men and women. It can be used to treat specific problems areas on the body such as upper arms, thighs and stomach, as well as the body as a whole.
Auricular acupuncture (ear acupuncture) and electro acupuncture (where a small electric currents is passed between pairs of acupuncture needles) are techniques frequently used for this treatment.
I would recommend one treatment per week for eight weeks, ideally on rest days from your exercise regime.
