Warning Signs

Body Checking

Body checking is the repeated, often compulsive, monitoring of your body's shape, size, or weight — through mirrors, scales, pinching, measuring, comparing, and more. It usually brings a moment of relief, but over time it feeds the very anxiety it's meant to soothe, which is why it's considered a behavior that helps keep eating disorders going.

A common, often invisible behavior that maintains eating disorders

Key takeaways

Body checking is the compulsive monitoring of your body to assess its size, shape, or weight — a very common feature of eating disorders.
It takes many forms: mirror checking, repeated weighing, pinching or measuring body parts, checking how clothes fit, comparing to others, and scrutinizing selfies or photos.
It tends to bring brief relief but increases distress over the long term, magnifying focus on perceived flaws — which is why clinicians call it a "maintaining factor."
Its opposite, body avoidance (refusing to look, be weighed, or be photographed), comes from the same underlying distress, and some people do both.
It is treatable. Awareness, structured reduction, and therapies like CBT-E and exposure work — ideally with professional support rather than willpower alone.

Overview

What is body checking?

Body checking is the habit of repeatedly monitoring your body to evaluate its shape, size, or weight, usually in an attempt to reduce anxiety about appearance. It is one of the most common behaviors seen across eating disorders — including anorexia nervosa, bulimia nervosa, and binge eating disorder — though milder forms occur in many people who do not have a diagnosed disorder.

What sets problematic body checking apart is not any single behavior but its frequency, the distress behind it, and how much it is driven by concerns about weight and shape. When checking becomes compulsive and starts shaping a person's day, it has moved from ordinary self-awareness into a warning sign.

What it looks like

Common examples of body checking

Body checking is often subtle and easy to hide. It commonly includes:

Repeatedly looking at oneself in mirrors, windows, or other reflective surfaces
Frequent weighing on a scale, sometimes many times a day
Pinching or grabbing areas of the body, or wrapping fingers around a wrist, arm, or thigh to gauge size
Measuring body parts, or checking whether bones are visible or whether thighs touch
Trying on specific clothing to test how it fits as a measure of body size
Comparing one's body to other people — in person, in photos, or on social media
Taking selfies or progress photos and scrutinizing them repeatedly
Seeking reassurance from others about how one looks

Because so many of these behaviors look ordinary from the outside, body checking often goes unnoticed by others — and sometimes by the person doing it.

The cycle

Why body checking backfires

Body checking feels like it should help — a quick check to "make sure" or to ease worry. And in the moment, it often does bring brief relief. The problem is what happens next.

In the widely used cognitive-behavioral model of eating disorders developed by Christopher Fairburn and colleagues, body checking is described as a maintaining factor: a behavior that does not just accompany an eating disorder but actively helps sustain it. Repeatedly scrutinizing the body magnifies selective attention to perceived flaws, heightens anxiety and body dissatisfaction, and reinforces the belief that one's appearance needs constant surveillance. That rising distress then fuels more restriction, purging, or other eating disorder behaviors — and prompts more checking. The short-term relief gives way to long-term escalation.

Two sides of the same coin

Body checking and body avoidance

The opposite pattern — body avoidance — springs from the same distress. Instead of monitoring the body, a person avoids any information about it: refusing to look in mirrors, wearing baggy clothing to obscure their shape, declining to be weighed, or avoiding photos and situations where the body is exposed.

Checking and avoidance are not opposites so much as two responses to the same underlying anxiety about the body. Many people move between them, or check some parts of the body obsessively while avoiding others. Both can interfere with recovery, and both are addressed in treatment.

Recognize

When body checking is a warning sign

Occasional glances in the mirror are normal. Body checking becomes a concern when it is frequent, hard to resist, tied to distress about weight or shape, and disruptive to daily life. Signs that it has crossed that line include checking many times a day, feeling anxious or compelled to check, having mood or eating decisions shaped by what the check "shows," and organizing activities around opportunities to check or avoid.

When body checking appears alongside other warning signs of an eating disorder — food restriction, preoccupation with weight, or distorted body image — it is worth taking seriously.

Getting unstuck

How to reduce body checking

Body checking can be reduced, but the goal is not to white-knuckle it away alone — for most people it works best as part of eating disorder treatment. Approaches that help include:

Build awareness first. Many checks are automatic. Keeping a simple log of when you check, what triggered it, and how you felt afterward makes the pattern visible.
Reduce gradually. Rather than stopping abruptly, many people cut checking in stages — for example, reducing mirror checks or weigh-ins step by step over time.
Identify triggers — situations, emotions, or times of day that prompt the urge — and plan for them.
Delay and ride out the urge. Urges to check tend to peak and pass; postponing and letting the feeling subside weakens the habit over time.
Remove some tools. Putting away the scale or tape measure, or covering or limiting mirrors, can reduce opportunities.
Enlist support. Trusted people can gently redirect you when they notice checking, and a therapist can guide the process.
Work with a professional. Enhanced cognitive behavioral therapy (CBT-E) and exposure and response prevention (ERP) have strong evidence for interrupting body checking as part of broader eating disorder treatment.

Next steps

When to seek help

If body checking is frequent, distressing, or bound up with restricting, purging, or preoccupation with weight and shape, it is worth reaching out. Body checking rarely exists in isolation, and addressing it is most effective within care for the underlying eating disorder.
