Appetite Regulation: Hormones, Stress, and Sleep
TL;DR
Why hunger is not purely willpower, and how leptin, ghrelin, cortisol, and sleep interact with metabolic health.
Hunger is biological
Appetite reflects hormones, sleep quality, stress, medications, and metabolic state. Telling someone to "eat less" without addressing drivers often fails.
Short sleep raises ghrelin and can blunt leptin signaling, increasing cravings independent of discipline.
Stress and cortisol patterns
Chronic stress can shift fat storage and appetite preferences. Cortisol patterns belong in a full fatigue and metabolic workup, not as a standalone wellness buzzword.
No supplement or protocol "cures" cortisol imbalance on public marketing claims. Physician review determines appropriate support.
Integrated metabolic care
Eterna IQ addresses appetite within metabolic health membership: labs, sleep and stress coaching, and prescription options when clinically appropriate.
An optimization analysis focused on body composition helps your care team understand whether metabolic pathways are the right starting point.
