Performance declines
Not improves with restriction
Athletes are at elevated risk for eating disorders — but athletic culture often normalizes restrictive eating and excessive exercise, making problems harder to recognize. The pressure to perform, make weight, or achieve a certain physique can push athletes across the line from dedication to disorder.
TL;DR — Key Takeaways: Athletes face 2-3× higher ED risk. RED-S (Relative Energy Deficiency in Sport) affects all genders and body systems. Under-fueling hurts performance — it doesn't help it. Warning signs include excessive training, rigid eating, frequent injuries, and menstrual loss. Coaches and trainers play a critical role in prevention and early detection.
Why Athletes Are at Higher Risk
Sport-Specific Pressures
- Weight-class sports: Pressure to "make weight"
- Aesthetic sports: Judging based on appearance
- Endurance sports: Belief that lighter = faster
- Team weigh-ins: Public body monitoring
- Uniforms: Revealing clothing increases body awareness
- Coaching comments: About weight or body composition
Personality & Culture Factors
- Perfectionism: Common athlete trait, also ED risk factor
- Competitiveness: Can extend to eating/weight
- Discipline: Restriction framed as "dedication"
- Pain tolerance: Ignoring hunger as mental toughness
- Identity: Self-worth tied to athletic performance
- Normalization: Disordered eating common in some sports
Risk by Sport Type
| Sport Category | Examples | Risk Level | Key Pressures |
|---|---|---|---|
| Aesthetic/Judged | Gymnastics, figure skating, diving, dance, cheerleading | Highest | Appearance judged, "ideal" body type, revealing uniforms |
| Weight-Class | Wrestling, boxing, rowing, martial arts, lightweight crew | Highest | Making weight, rapid weight cycling, weigh-ins |
| Endurance | Distance running, cycling, triathlon, swimming | Elevated | "Lighter is faster" belief, high training volume |
| Gravitational | High jump, pole vault, ski jumping | Elevated | Power-to-weight ratio emphasis |
| Ball/Team Sports | Soccer, basketball, volleyball, softball | Moderate | Body comparison, pressure varies by position |
Important: Athletes in ANY sport can develop eating disorders. These categories indicate relative risk, not absolute risk. Individual factors, coaching environment, and team culture all play significant roles.
RED-S: Relative Energy Deficiency in Sport
From the Female Athlete Triad to RED-S
The "Female Athlete Triad" concept has expanded to RED-S — recognizing that energy deficiency affects ALL athletes and multiple body systems.
Low Energy Availability
Not eating enough to fuel training. The root cause.
Bone Health
Stress fractures, osteoporosis, impaired bone development.
Hormonal Function
Menstrual dysfunction (females), low testosterone (males).
RED-S affects male athletes too. Despite the historical "Female Athlete Triad" name, relative energy deficiency causes hormonal, bone, and performance problems in athletes of all genders. Male athletes often go unrecognized.
RED-S Effects on the Body
Cardiovascular
Bradycardia, hypotension, arrhythmias
Psychological
Depression, irritability, impaired judgment
Bone
Stress fractures, osteoporosis
Muscular
Decreased strength, impaired recovery
Immune
Increased illness, slow healing
Endocrine
Menstrual loss, low testosterone
Metabolic
Slowed metabolism, GI issues
Performance
Decreased endurance, strength, coordination
The Performance Paradox
Athletes often restrict eating to improve performance, but the opposite happens:
- Decreased endurance and strength
- Impaired reaction time
- Reduced coordination
- Poor recovery between sessions
- Increased injury risk
- More frequent illness
- Mental fog and poor decision-making
Fueling properly IS a performance strategy.
Warning Signs of RED-S
- Recurrent stress fractures or injuries
- Loss of menstrual period (females)
- Declining performance despite training
- Frequent illness
- Fatigue that doesn't improve with rest
- Mood changes, irritability
- Difficulty concentrating
- Growth delays in adolescents
- Poor recovery between sessions
Warning Signs in Athletes
Eating disorders can be harder to spot in athletes because some behaviors (exercise, attention to nutrition) are normalized. Look for these patterns:
🏋️ Training Behaviors
- Exercising beyond what coach prescribes
- Distress if unable to exercise
- Training through injury or illness
- Secret extra workouts
- Exercising to "earn" food or "burn off" meals
- Obsession with activity trackers/calories burned
🍎 Eating Patterns
- Avoiding team meals or eating alone
- Rigid "clean eating" rules
- Cutting out food groups (carbs, fats)
- Eating less than teammates with same training load
- Pre-occupation with food, calories, macros
- Disappearing after meals (possible purging)
📉 Performance Changes
- Declining performance despite training
- Frequent injuries, especially stress fractures
- Slow recovery
- Frequent illness
- Fatigue, low energy
- Difficulty concentrating
🧠 Psychological Signs
- Body image distress
- Comparing body to teammates
- Anxiety about weight or body composition testing
- Self-worth tied entirely to performance
- Withdrawal from team social activities
- Mood changes, irritability, depression
Prevention & Healthy Culture
Creating Safer Athletic Environments
- No public weigh-ins — if weight monitoring needed, do privately with trained staff
- No body shaming — comments about weight, even "positive," are harmful
- Focus on performance — not body composition
- Sports nutrition education — fuel as performance tool
- Rest is training — recovery is essential, not weakness
- Model healthy behaviors — coaches' attitudes matter
- Screen for RED-S — regular health monitoring
For Athletes Themselves
- Food is fuel — under-eating hurts performance
- Rest is required — muscles grow during recovery
- Your body is your instrument — treat it well
- Speak up — about harmful practices or comments
- Seek help early — problems caught early recover faster
- Career is temporary — your health is forever
- Your worth ≠ your performance
The science is clear: Adequately fueled athletes perform better, recover faster, get injured less, and have longer careers. Restriction is not a competitive advantage — it's a career-ender.
Who Can Help
Coaches
- Create culture where food is fuel
- Never comment on athletes' weight
- Recognize warning signs
- Know when to refer to professionals
- Prioritize long-term health over short-term performance
- Model healthy behaviors
Athletic Trainers
- Screen for RED-S
- Monitor for concerning patterns
- Coordinate with medical staff
- Advocate for athlete health
- Provide confidential support
- Know referral resources
Sports Dietitians
- Provide individualized nutrition plans
- Educate on fueling for performance
- Identify disordered eating early
- Support recovery while maintaining sport
- Combat nutrition misinformation
- Work with treatment teams
When to Remove from Competition
Medical clearance should be required to return to sport when an athlete shows:
- Significant weight loss or unstable weight
- Abnormal vital signs (low heart rate, blood pressure)
- Electrolyte abnormalities
- Stress fractures (may indicate RED-S)
- Loss of menstrual period (females)
- Signs of dehydration or acute medical instability
The athlete's health comes first — always. Return-to-play decisions should involve medical professionals, not just coaches.
