Cortisol and intermittent fasting: How to balance hormetic stress and recovery

Fasting can build metabolic resilience when aligned with the body’s diurnal cortisol curve. Short, recoverable stress supports energy balance and repair, while chronic elevation undermines it. Because fasting isn’t one-size-fits-all—especially for many women—tracking cortisol levels with Hormometer™ helps reveal when your routine drives adaptation and when it signals overload.

How Cortisol Shapes Energy, Weight, and Digestion

Cortisol connects stress, energy, and metabolism. When balanced, it supports focus and digestion; when elevated, it slows metabolism and redistributes fat. This article breaks down how stress reshapes energy use—and how visualizing cortisol with Hormometer™ can help restore balance.

How Cortisol and Facial Aging Intersect

Discover how cortisol—the body’s key stress hormone—links energy, recovery, and skin health. When balanced, it supports focus and repair; when elevated, it accelerates aging by breaking down collagen. Explore how biohackers use cortisol insights to fine-tune habits like cold exposure, red light, and sleep for healthier skin and sustained vitality.
