Words mean things
And the word addiction is such a loaded one.
And we really do use it frivolously when describing how we consume food.
The right word is we are habituated to eating too much and for the wrong reasons.
You can change habits and eat for the right reasons. And occasionally in moderation for pleasure.
Question always is are you motivated enough to make it happen. Or will you resort to clumsy excuses and poor selection of words to justify your bad habits.
