I know for a fact I have an addictive personality so instead of being addicted to things like drugs or alcohol I concentrate my addiction on things like running, rowing, hiking, and activity in general.
If I were A food addict I would do the same and by that I mean instead of being addicted to sweets into cake I would focus my addiction on vegetables, fruit, and such.
I understand addiction and there's a lot of it in my family but it should never be used as an excuse. Use it to mold good to behavior in excess as opposed to bad behavior in excess.
