Don’t get pierced! Body piercings can raise cortisol levels and lead to fat gain, and no site is as susceptible to fat gain as your abs! If you have a navel piercing, remove it and chances are you’ll lose fat in the abdominal area. I’ve seen it numerous times, and anyone who has been to my Biosignature classes has probably had the benefit of witnessing the dramatic drop in belly and total body fat over just five days when attendees remove their navel piercings.
The justifications include some pretty abysmal references, relying on acupuncture and traditional Chinese medicine, but there are are a few sources in there that look legitimate.
Is there any experimental evidence to suggest that a (typical) body piercing may lead to fat gain?
