Intervention matters
Warning signs vary by person and by disorder. Someone struggling with an eating disorder won't show all these signs at once — and many signs can be hidden or explained away. The key is noticing patterns and changes, not checking off a list. Trust your instincts. If something feels wrong, it probably deserves attention.
TL;DR — Key Takeaways: Look for behavioral changes first (food rituals, avoidance, secrecy). Physical signs often come later. Emotional changes matter too (withdrawal, mood shifts, perfectionism). You can't tell by weight alone — EDs happen at any size. When in doubt, ask with care. The SCOFF screening tool can help.
⚠️ Critical reminder: You cannot tell if someone has an eating disorder by looking at them. Less than 6% of people with eating disorders are medically underweight. Eating disorders affect people of all body sizes — and many of the most dangerous cases occur in people who appear "healthy" or are even in larger bodies.
Physical Signs
Physical Warning Signs
Changes you might notice in the body — often appear after behavioral changes
•
Weight fluctuations — noticeable changes (up or down) over a short period, or dramatic weight loss
•
Dizziness or fainting — especially when standing up (orthostatic hypotension)
•
Always cold — feeling cold even in warm temperatures, wearing layers indoors
•
Fatigue & weakness — lack of energy, difficulty concentrating, muscle weakness
•
Hair changes — thinning hair on head, fine downy hair (lanugo) on body/face
•
Dry skin, brittle nails — signs of nutritional deficiency
•
GI problems — stomach cramps, constipation, acid reflux, bloating
•
Menstrual irregularities — missed periods, loss of menstrual cycle
•
Dental problems — enamel erosion, cavities, discoloration (from purging)
•
Swollen cheeks/jaw — enlarged salivary glands ("chipmunk cheeks")
•
Russell's sign — calluses or scarring on knuckles from self-induced vomiting
•
Slow wound healing — cuts and bruises take longer to heal
Note: Many physical signs only appear after significant harm has already occurred. Behavioral and emotional changes often appear earlier — don't wait for physical symptoms to seek help.
Behavioral Signs
Behavioral Warning Signs
Changes in actions and routines — often the earliest observable signs
•
Frequent dieting — constant new diets, eliminating entire food groups, "clean eating" obsession
•
Skipping meals — making excuses to avoid eating ("I already ate," "I'm not hungry")
•
Compulsive exercise — rigid exercise routines, exercising when sick/injured, distress if unable to exercise
•
Social withdrawal — avoiding events involving food, isolating from friends/family
•
Bathroom trips after meals — frequently excusing themselves to bathroom immediately after eating
•
Hiding/hoarding food — stockpiling food in unusual places, eating in secret
•
Clothing changes — wearing baggy clothes to hide body, layering up

Body checking — frequent mirror checking, pinching body parts, obsessive weighing
•
Cooking for others — making elaborate meals for others but not eating themselves
•
Calorie tracking — obsessive counting, reading every label, using food tracking apps excessively
•
Evidence of purging — laxative/diuretic packages, running water to cover sounds
•
Disappearing food — large amounts of food missing, empty wrappers hidden
Emotional & Psychological Signs
Emotional & Psychological Signs
Changes in mood, thinking, and self-perception — often the strongest indicators
•
Preoccupation with weight/body — constant talk about being "fat," body checking, comparison to others
•
Distorted body image — perceiving themselves as larger than they are, not seeing thinness others see
•
Mood swings — irritability, especially around mealtimes or when food plans change
•
Anxiety around food — visible stress at restaurants, family dinners, any unplanned eating
•
Guilt after eating — shame, self-criticism, needing to "make up for" eating
•
Black-and-white thinking — foods are "good" or "bad," "safe" or "forbidden"
•
Perfectionism — intense drive to be perfect, harsh self-criticism, fear of failure
•
Fear of losing control — around food, weight, eating situations
•
Low self-esteem — self-worth tied to weight, appearance, or eating "perfectly"
•
Depression symptoms — hopelessness, withdrawal, loss of interest in activities
•
Denial — insisting nothing is wrong despite clear changes, getting defensive when asked
•
Difficulty concentrating — brain fog, trouble thinking clearly (often from malnutrition)
Food-Related Signs
Food Rituals & Eating Patterns
Specific behaviors around eating that may signal a problem
•
Food rituals — eating foods in a specific order, excessive chewing, cutting into tiny pieces
•
Rearranging food — moving food around plate to make it look eaten
•
Eating very slowly — taking an unusually long time to finish small amounts
•
Eating very quickly — consuming large amounts rapidly, as if racing
•
Only eating "safe" foods — increasingly narrow list of acceptable foods
•
Avoiding eating in public — won't eat at restaurants, parties, or in front of others
•
Strange food combinations — mixing unusual foods, excessive condiment use
•
Drinking excessive water — before/during meals to feel full, or excessive fluid intake
•
Using food substitutes — excessive gum chewing, zero-calorie drinks, diet products
•
Eating past fullness — unable to stop eating until uncomfortably or painfully full
Quick Self-Check: The SCOFF Screening
The SCOFF Questions
A validated 5-question screening tool used by healthcare providers. This is not a diagnosis — it's a signal to seek professional evaluation.
S
Do you make yourself Sick (vomit) because you feel uncomfortably full?
C
Do you worry you have lost Control over how much you eat?
O
Have you recently lost more than One stone (14 lbs / 6.4 kg) in a 3-month period?
F
Do you believe yourself to be Fat when others say you are too thin?
F
Would you say that Food dominates your life?
Scoring: "Yes" to 2 or more questions indicates a likely case of an eating disorder. Seek professional evaluation.
Important: A negative SCOFF result doesn't mean you're fine — it means this particular screen didn't flag a concern. If you're worried about your relationship with food, trust that instinct. The SCOFF also doesn't screen for ARFID, BED, or other eating disorders well.

How to Help: Starting the Conversation
What to Say (and What to Avoid)
✓ Do Say
- "I've noticed some changes and I'm worried about you"
- "I care about you and I'm here if you want to talk"
- "This isn't about how you look — I'm concerned about how you're feeling"
- "You deserve support. Can we look at options together?"
- "I'm not judging you. I just want to understand"
- "Recovery is possible and I'll support you"
✗ Avoid
- "You look great/thin/healthy!" (any comment on appearance)
- "Just eat" or "Why can't you just stop?"
- "You don't look like you have an eating disorder"
- "I wish I had your willpower"
- "You're being dramatic/attention-seeking"
- "You're too smart for this"
- Commenting on their food choices at meals
📋 Before the Conversation
- Choose a private, calm moment — not at a meal
- Prepare what you want to say
- Research treatment resources beforehand
- Accept that they may deny or become defensive
- Be prepared to just listen
- Don't wait for the "perfect" moment — it won't come
📋 After the Conversation
- Don't expect immediate change
- Don't take on the role of therapist
- Continue to show you care without pressure
- Follow up — one conversation is rarely enough
- If they're a minor, involve parents/guardians
- Take care of your own wellbeing too
If they're in immediate danger — fainting, chest pain, severe dehydration, suicidal thoughts — don't wait for consent. Seek emergency medical help. Their safety comes first.

✓ Trust your instincts — if something feels wrong, it probably is
✓ Earlier intervention = better outcomes
✓ Focus on concern for wellbeing, not appearance
✓ One conversation won't fix it — stay present and patient
