Oddly enough, when my hyper-religious ex SIL decided enough was enough and wanted to lose weight, she joined a weight loss group at her church.  Can't recall what it was called. Anyway, she lost about 50 lbs (probably about still 15 over). The premise was that outside of regular meals, when you had the urge to eat (she was an emotional eater),  you should pray instead.  Being hyper religious, she credits the weight loss to Jesus.  Not the fact that she no longer ate a 2 lb bag of M & Ms in a sitting.  Lol.
