Andrew Huberman

Jul 17, 2025

Episode description

In this Huberman Lab Essentials episode, I discuss both healthy eating and clinically recognized eating disorders, including anorexia, bulimia and binge eating disorder.

I explain how brain circuits, hormones such as leptin and reward systems interact to regulate appetite, satiety and overall eating behaviors. I also discuss the serious health risks associated with anorexia, explain how disrupted eating habits contribute to its development and highlight evidence-based treatments for anorexia. Finally, I explore binge eating and bulimia, discussing the underlying causes and the pharmacological treatments commonly used to support recovery.

Mindsip insights from this episode:

Define your own healthy eating plan based on personal metrics

No expert can define the single best eating plan for any individual, as 'healthy' is defined only by personal measurements like blood work, performance, and mood.

Address impulse control in bulimia with ADHD treatments

Bulimia is characterized by a lack of inhibitory control due to an underactive prefrontal cortex, which is why drugs that treat ADHD by boosting focus can also be effective.

Recognize anorexia as a disorder of habit formation

Anorexia is a disorder of habit formation, where the brain's reflexive, subconscious pathways, not conscious decision-making, drive the avoidance of certain foods.

Rewire reward circuits to understand anorexia's food avoidance

Anorexics are not consciously punishing themselves; their brain's reward circuits have been rewired to provide a sense of pleasure and reward for avoiding high-fat foods.

Recognize distorted self-perception in anorexia through VR studies

Anorexics suffer from a genuine visual perception defect, causing them to see themselves as overweight, a phenomenon confirmed in VR studies where they inaccurately adjust their own avatars.

Utilize intermittent fasting for easier dietary control

Many people find intermittent fasting effective simply because it's psychologically easier to abstain from eating entirely than to practice portion control.

Recognize anorexia's historical stability as a biological issue

Contrary to popular belief, rates of anorexia have remained stable for the last 400 years, suggesting a strong biological cause rather than influence from modern media.

Leverage body fat and leptin to enhance fertility

The hormone leptin, secreted by body fat, signals to the brain that there are sufficient energy stores to support fertility, triggering ovulation in females and sperm production in males.
