I’m Restricting What I Eat or Skipping Meals, When Should I Be Concerned
Skipping a meal occasionally does not by itself mean somebody has an eating disorder.
Skipping a meal occasionally does not by itself mean somebody has an eating disorder.
The concern is the pattern and what is driving it.
You may be deliberately eating less because you are frightened of weight gain, following increasingly rigid food rules, avoiding meals after eating earlier, hiding restriction from other people or feeling distressed when circumstances make you eat differently from your plan.
Restriction can affect physical health, and it is something to discuss with a GP rather than trying to judge the medical risk yourself.
Restriction can become progressively normal to you
Changes often happen gradually.
A rule that initially felt unusual can become the new baseline, followed by another rule. You may stop noticing how much planning is required to avoid food or how often social activities are being shaped around eating.
People close to you may notice changes before you feel ready to call them a problem.
Do not use body size as your safety check
You cannot reliably decide whether restriction is medically safe by looking in the mirror or comparing your body with photographs of people with eating disorders.
NICE tells professionals not to use BMI alone when deciding whether treatment should be offered.
The pattern of restriction, rate of change, physical symptoms, mental health and wider circumstances all matter.
Tell a healthcare professional about physical symptoms
Restriction can affect the body in ways that need assessment.
NICE highlights symptoms including dizziness, fainting, palpitations, poor circulation and pallor among signs professionals should consider when assessing a possible eating disorder.
If you are experiencing physical changes, tell your GP. Do not try to use online information to calculate whether you have reached a medically dangerous threshold.
Avoid turning this into another set of food rules
This guide will not provide calorie targets, target weights, meal-restriction techniques or instructions for compensating for food.
If restriction is becoming established, individual nutritional and medical needs should be assessed by appropriately qualified professionals. NICE says dietary counselling for anorexia nervosa should be part of a multidisciplinary approach rather than a stand-alone intervention.
Ask for help while you can still see the pattern
You do not need to wait until restriction feels completely beyond your control.
Tell your GP what you have stopped eating, how your eating has changed, what happens emotionally when you try to eat differently and any physical symptoms.
If an eating disorder is suspected, NICE recommends referral for specialist assessment or treatment.

Eating disorders can affect physical as well as mental health, and appearance or body weight alone does not show how unwell somebody may be. If you are worried about your eating, food-related behaviours, body image or physical health, speak to your GP or another appropriately qualified healthcare professional. If an eating disorder is suspected, specialist assessment should be arranged as early as possible.
