You have some very good points. Binging is considered a psychological problem by many, if not most experts and people in general. People also talk about "emotional eating" and "comfort eating" and such.

I'm not sure that binging is brought on by lack of nutrients, though, because when I was binging I supplemented AND I ate so much food anyway that it would be hard not to get the nutrients, though I suppose it's possible since grains are anti-nutrients. But it's such an immediate response -- like blood sugar rising and dropping. I think it's more likely caused by hormonal response rather than nutritional.

It would be interesting if this were actually studied. It actually is VERY freeing realizing that my binging is caused by physical factors, no matter what those physical factors are, rather than psychological.
