As a Christian of only 10 months now, my life has improved drastically. I finally know which way is up. I've quit caffeine, masturbation, pornography, and am looking to let Jesus help heal the wounds that caused my homosexuality. The one thing that doesn't seem to improve is my diet. Don't get me wrong; I can practice saying no. But, I have become so obsessed with diet that in the past I did some dangerous fasting and various silly attempts at "purging". There's never a happy medium though; the literature I've read says that abstenance can make you binge, which is certainly the case for me because I've recently put on a lot of weight from bingeing.

I'm just wondering if anyone has suffered from this or has any Biblical advice on how to deal with gluttony?
