What treatment for restrictive eating actually involves

· Dr Rachel Megahy

The most common reason people delay getting help is not knowing what they would be agreeing to. That's reasonable. The word “treatment” carries a lot of implication, and if what you picture is being made to eat things while somebody watches, it makes sense to put off the phone call.

So here is what it actually involves.

It starts with understanding, not eating

The first sessions are assessment. That means talking — about how your eating developed, what the current pattern is, what you can manage and what you can't, what has been tried before and how it went.

Nothing changes about your eating during this phase. That is deliberate, and not just to be gentle about it. Restrictive eating patterns are specific to the person, and an intervention built on assumptions rather than information tends to target the wrong thing.

By the end of assessment you should have something you didn't have before: a clear account of what maintains the pattern. Most people find this stage more useful than they expected. Having your eating explained back to you as a coherent mechanism, rather than a personal deficiency, does a certain amount of work on its own.

Then a plan you agreed to

What follows depends on what the assessment found, but it is drawn from established approaches — CBT-AR for avoidant and restrictive presentations, with elements of compassion-focused work where shame is prominent, which it usually is. You can read more about my eating disorders work.

The core of it is graded exposure: approaching avoided foods in steps small enough to be manageable, repeated often enough for the anxiety to settle. You set the steps. If a step is too big, it gets broken down. Nothing is sprung on you, and nothing happens that you haven't agreed to in advance.

Alongside that, there's usually work on the beliefs holding the pattern in place — what you expect to happen, how likely it actually is, and what you'd do if it did. And often work on the shame, which for many people is doing more damage than the eating.

The pace

Slower than people expect, and that is the point.

The pace that produces change is the one you can sustain. Going too fast produces an aversive experience, and an aversive experience sets you back further than the ground you gained. I would rather spend three sessions on one food and have it hold than push through six and lose them all.

Sessions are weekly to begin with, usually spreading out as things become more stable. Length of treatment varies considerably — some people need a few months, some longer, and it depends much more on how entrenched the pattern is than on how severe it looks.

Physical health sits alongside

Psychological treatment is not a substitute for medical care, and a long-standing narrow diet can produce deficiencies worth checking.

I ask that people are registered with a GP and are willing for me to be in contact where it's useful. If physical health needs active monitoring, that needs to be in place alongside the psychological work rather than instead of it — and if what you need is a level of care beyond weekly outpatient sessions, I would tell you that at assessment and help you find the right route. Saying so early is part of doing this properly.

What good progress looks like

Not a normal diet. That's the wrong target, and holding it makes people feel like they're failing when they're doing well.

The realistic outcome is a meaningfully wider range of foods you can rely on, and a meaningfully smaller set of situations you have to avoid. Being able to eat at a friend's house. Ordering from a menu without a preliminary phone call. Going on holiday without packing food.

Most people can name the specific things restriction has cost them. Those are the targets, and they're the right ones.

If you're considering it

You don't need a diagnosis, and you don't need to have reached crisis point. If eating has become effortful and limiting, that's reason enough for a conversation. There is also a self-paced online course in development for people who would rather start on their own.

Assessment is one to two sessions and carries no obligation to continue. You are allowed to come, find out what's involved, and decide it isn't the right time.

I'm not able to offer crisis support. If you need urgent help, contact your GP, call NHS 24 on 111, or call 999 in an emergency. See urgent support options
