The leptine sensibility and others treated the results and/or symptoms of a body in oriental medicine. Acupuncture is to make organs work as they are supposed to. Of course, the manipulation of one single acupuncture point may make the differences on those. However, those symptoms shall be treated by systematical approach.
Although one single acupoint can fix a problem with a history more than ten years, in many cases, acupoints are required to make the treatment optimal.
Prof.Zafar, I read that the leptine metabolism is similar as insulin, and the body at moment thar we do not know, lose the sensibility for this hormone, I think that acupuncture stimuli enhance the sensibility to insulin it will happend with leptine.
