When You Couldn’t Say No: Eating Disorders and the Hunger for Boundaries

Eating disorders are often framed as problems with food, weight, or control.

But beneath the behaviours, there is often something far more relational and developmental at play:

Boundaries.

Many eating disorders can be understood as the body expressing a “no” that was never allowed to be spoken.

Boundaries Are Not Walls

A healthy boundary is not rigid. It’s not aggressive. It’s not a rejection of connection.

A boundary is more like a semi-permeable membrane.

It filters, contains, and differentiates.

It allows you to stay intimately connected to others and to life without collapsing into them or abandoning yourself.

Healthy boundaries bring energy. They prevent depletion. They allow sovereignty.

Saying “no” to what harms or exhausts you is saying “yes” to yourself.

Early Boundary Ruptures

Many eating disorders originate in early developmental stages, often in the preverbal phase of childhood.

Before we had language.

Before we could say:

“No.”
“Stop.”
“That doesn’t feel okay.”
“I need space.”
“I need comfort.”

In those early years, power dynamics are real. Survival depends on attachment. If asserting a boundary risks connection, children will override their own boundaries to maintain safety.

When the defensive impulse—the natural “NO!”—is blocked, the energy of that response doesn’t disappear and instead gets stored.

Undigested boundary responses can remain in the nervous system and body. Over time, they shape how we relate to ourselves, to food, to our bodies, and to other people.

Eating Disorders as Boundary Strategies

If direct expression of needs was unsafe, the body may find indirect routes.

Restriction can become: “I will only take up this much space.”

Excessive exercise can become: “If I harden myself, nothing can penetrate me.”

Purging can become: “The no I cannot say out loud.”

Orthorexia can become: “You cannot make me consume what feels unsafe.”

Bingeing can become: “I am exhausted from saying yes. This is my shutdown.”

These behaviours are not random. They are adaptive attempts to filter, protect, contain, or push back.

They are not moral failures. They are strategies.

But strategies that once protected can later begin to harm.

Recovery Is Boundary Work

Healing is not just about changing eating behaviours.

It’s about learning to metabolize and express boundaries in real time.

To feel:

• When something is too much
• When something is unwanted
• When you need space
• When you need care
• When you need to say no

And to communicate that directly without punishing your body.

As boundaries become embodied rather than acted out through food, energy returns. Relationships shift. Sovereignty strengthens.

You can remain connected without disappearing.

Healthy Boundaries Bring Energy

A well-differentiated person is not disconnected. They are clear and present.

Clear about what they will take in. Clear about what they will not.

When boundaries function as filters rather than walls, intimacy deepens, because connection is chosen, not endured.

If you find yourself stuck in cycles of restriction, bingeing, purging, or over-exercising, it may be worth asking:

Where did I learn that I couldn’t say no?

And what would it look like to begin practicing that now?

If you’re ready to explore this work, I offer 1:1 somatic support for eating disorder recovery and rebuilding body trust. Together we work at the level of the nervous system, where boundaries first formed.

You don’t have to keep letting your body say what you were never allowed to.

You can learn to say it yourself.
