Yale Food Addiction Scale (YFAS)
Yale Food Addiction Scale · Also known as: YFAS 2.0, Yale Food Addiction Scale Revised
The YFAS is a self-report questionnaire measuring symptoms of addictive-like eating behaviour in response to highly palatable foods. Developed by Gearhardt, Corbin, and Brownell in 2009, it is based on diagnostic criteria for substance use disorder and adapted to assess dependence-like symptoms related to food consumption. The YFAS 2.0, released in 2016, improved psychometric properties and reduced item burden. It is used in research on obesity, food addiction, and eating behaviour regulation.

When to use it
The YFAS 2.0 is used in research on food addiction, obesity, eating behaviour, and neurobiological mechanisms of food craving. It is appropriate for adolescents (14+) and adults. It may be helpful in identifying individuals in weight loss treatment who show addiction-like eating patterns and might benefit from specialized interventions. The YFAS is not diagnostic; it is a research and screening tool. It is not endorsed by diagnostic manuals (food addiction is not in DSM-5) and should not be used to label individuals clinically without caution.
Strengths & limitations
- Structured measurement of addiction-like eating symptoms — operationalizes food dependence through DSM-5-mapped criteria, providing systematic assessment of loss-of-control eating.
- YFAS 2.0 refinement — shorter (35 vs. 25 items in version 1.0), improved reliability, and clearer threshold for 'clinically significant' classification.
- Research utility — useful for identifying individuals with food-related compulsion and investigating neurobiological mechanisms (reward sensitivity, executive function impairment).
- Predicts treatment response — individuals scoring high on YFAS show worse outcomes in standard weight loss interventions, suggesting potential need for specialized treatment.
- Translated into 20+ languages and validated across diverse populations.
- Controversial construct — 'food addiction' is debated in the scientific community; some argue that the analogy to substance addiction is problematic given food's necessity for survival and absence of pharmacological action.
- Does not diagnose clinically recognized disorder — food addiction is not in DSM-5; the YFAS uses substance use criteria adapted post-hoc to food.
- Subjective functional impairment assessment — the 'clinically significant' threshold relies on self-report of impairment, which may not align with objective functional outcomes.
- Does not distinguish addiction from binge eating or other eating disorders — high YFAS scores may reflect binge eating, emotional eating, or loss-of-control eating without true addiction-like neurobiological changes.
- Limited mechanistic specificity — measures behaviours/symptoms but not underlying neurobiological mechanisms (e.g., dopamine dysregulation, reward processing).
Frequently asked
Is food addiction a real diagnosis?
Food addiction is not recognized as a diagnosis in DSM-5 or ICD-11. The YFAS measures behaviours and symptoms resembling addiction but does not establish a clinically recognized disorder. The concept remains scientifically debated. Use YFAS as a research tool to measure addiction-like eating symptoms, not as a basis for clinical diagnosis without caution and additional assessment.
What's the difference between food addiction (YFAS) and binge eating disorder?
Food addiction (YFAS) focuses on loss-of-control eating and addiction-like symptoms (tolerance, withdrawal, continued use despite harm). Binge eating disorder (diagnosed by EDE or DSM-5 criteria) requires discrete binge episodes (eating large quantities with loss of control), occurring ≥1 per week for ≥3 months, with emotional distress. Overlap exists; many individuals with BED score high on YFAS, but they are distinct constructs measurable by different tools.
I scored 5 symptoms on YFAS 2.0. Does this mean I have food addiction?
Meeting ≥2 symptoms suggests possible food addiction risk, but you also must report clinically significant impairment (distress affecting work, social life, health). Five symptoms without impairment may indicate difficulty controlling eating but not clinical food addiction per YFAS criteria. Discuss with a healthcare provider for proper assessment.
Can YFAS help predict weight loss success?
Yes, to some degree. Individuals meeting YFAS food addiction criteria typically show poorer response to standard weight loss dieting. Higher YFAS scores suggest need for specialized treatment targeting food cravings, emotional regulation, and food environment modification. Combine YFAS screening with other assessments (binge eating, emotional eating) for comprehensive prediction of treatment need.
