We’re All Addicts

I am a scholar for a year. I managed to lose 35 pounds and gain 30 of them back.
I learned a lot about how my brain works, how it is wired and what causes my feelings and actions.
What I also realized is that as a human for the rest of my life I will always have to watch out for a returning desire for false pleasures of certain foods.
If this past year had taught me anything is that the moment I eat a joy eat, all that craving and all those urges come right back.
And this realization made me frustrated because I thought that once I tamed it and lost all my extra weight I will never have to deal with it again.

Looking at all these questions of other scholars here over the past months proves that they all fall back, eat a joy eat, introduce the desire again and need to tame it from the start.
How does this make us any different than drug addicts or alcoholic who abstain from alcohol for the rest of their lives?
