Maybe. In a small study researchers found that acupuncture increased Leptin levels. And it really was the acupuncture points, because patients receiving sham acupuncture didn’t get the same increases.
What I really like about the study was that researchers did the acupuncture with electoacupuncture. By using electricity rather than needles, the research opens the way to having patients see their acupuncturist a few times a month but continuing daily treatment with their own electoacupuncture machines. The machines are relatively simple to use if the point is marked on the body, are cheap, and typically run on a single nine volt battery.
