For some people, food became a stand-in for other people.
Food is dependable. It doesn't need anyone to show up, so it can't let you down. Someone who learned early that needing people leads to being smothered or being left has good reason to prefer it. Many go a step further and teach themselves not to want anything at all.
Where it starts
Babies can't settle themselves. Someone else does it for them, over and over, until the child's own system learns how. When that help was missing or unpredictable, the child still has to do something with a feeling that's too big. It doesn't take a catastrophe. A parent who was anxious in a way nobody named, or kind but not quite there, can be enough.
Food is one of the first things a child can use alone. It works every time. It doesn't have a bad day, or get overwhelmed, or leave. When the people around a child were too much or not enough, food can become the one relationship that child trusts, precisely because there is no person in it.
Too close or too far
Often the trouble was that both choices on offer were bad ones. Get close, and risk being swallowed by someone else's needs and worries. Pull back, and risk being left alone. A child can't solve that. Researchers describe the result as insecure attachment, and it turns up again and again in people with eating disorders.
Food offers a way out of the bind. It can be taken in or refused on the person's own terms. It gives comfort without asking for anything back, and it never crowds.
Not wanting to want
An eating disorder is usually described as a problem with food. It can also be understood as a problem with wanting.
If wanting is what got a person hurt, the safest thing is to stop. Need gets shut down, at the table and everywhere else. From the outside it can pass for discipline.
Wanting doesn't go away that easily, though. One way to understand restricting is that refusing food keeps desire alive at a safe distance. Nothing becomes the thing that is wanted, and nothing can't be withheld or taken away.
Bingeing and purging can be read as the opposite: wanting breaking through. It comes with a feeling of never being able to get enough, often alongside anger that has nowhere else to go. It can also be an attempt to have everything at once, in the one relationship where nothing gets taken away. For some people the binge is the only part of the day that belongs to no one else. It's a terrible way to get that, and it is still a way to get it.
What getting better asks
Against that history, getting better asks for something very large. At the exact moment the dependable thing is within reach, it asks the person to turn toward an undependable one: a human being, who might be slow, or irritated, or simply not there.
From the outside that looks like an obvious trade. From the inside it means giving up the one thing that has always worked for something that often hasn't. What would make that feel worth trying?
