As an appetite suppressant? I'm not sold on ear reflexology. I think the principle is that it is supposed to promote relaxation and lower cortisol levels. Higher cortisol levels are linked with over eating for energy because the body thinks it's in danger and prepares to fight or flight. If the ear studs work it's due to a placebo effect in my opinion, you'd need to believe they were going to work. Praying in the spirit has been scientifically proven to lower cortisol. You'd be better off having some time with Jesus.
