Dopamine Hunt: ADHD and Eating Disorders
Neurobiological reasons for stimulation hunger underlying binge eating episodes and pharmacological treatments.
Sugar as Self-Medication
Assoc. Prof. Dr. Eylem Özten Özsoy notes that individuals with ADHD (particularly women) frequently present at eating disorder clinics. The most common presentation is Binge Eating Disorder (BED).
A brain whose prefrontal cortex is starving for dopamine finds its fastest "legal drug" in the kitchen: sugar and simple carbohydrates. The insatiable sweet cravings that strike at midnight are often not the body being hungry, but the brain’s desperate cry: "Give me dopamine!" Eating is used impulsively as a tool to stimulate the brain's reward center.

Hyperfocus and the Shutdown of Hunger Cues
The other side of the coin is "forgetting to eat." When an individual with ADHD hyper-focuses on a topic of interest, their interoceptive sense—the internal system that perceives bodily signals like hunger or thirst—literally shuts down.
After working all day without consuming anything, the person enters the kitchen late at night with a "fatal hunger" and consumes a massive amount of food rapidly. Breaking this cycle requires moving away from "willpower" and toward external automation: setting protein-focused meal alarms and pursuing pharmacological treatment to balance dopamine levels.
