Food Addiction and Obesity
A pattern of compulsive overeating driven by the same brain reward pathways involved in substance addiction.
Plain English
Patient-Friendly Explanation
Food addiction describes a pattern where certain foods — especially those high in sugar, fat, and salt — trigger strong cravings and loss of control, much like addictive substances. You may find yourself eating even when you are not hungry or struggling to stop once you start. This is not a lack of willpower; it reflects real changes in how your brain responds to highly processed foods, making weight loss especially challenging without the right support.
Medical
Clinical Definition
Food addiction is conceptualised within the framework of substance use disorders, with highly palatable, ultra-processed foods acting on dopaminergic mesolimbic reward pathways similarly to drugs of abuse. The Yale Food Addiction Scale (YFAS) operationalises diagnostic criteria adapted from DSM-5 substance use disorder criteria — including loss of control, tolerance, withdrawal, and continued use despite negative consequences. Neuroimaging studies demonstrate that individuals meeting YFAS criteria exhibit reduced striatal D2 receptor availability and blunted reward-circuitry activation, paralleling findings in substance addiction. The condition is distinct from binge eating disorder, though comorbidity is common.
Key Insight
Why It Matters
Recognising food addiction as a neurobiological condition rather than a character flaw is the first step toward effective treatment. At Accord Medical, Dr. Joseph Wang takes a comprehensive approach that may combine medical weight management with behavioural therapy and nutritional counselling to address the root causes of compulsive eating patterns.
