Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — cortisol and fat metabolism

Cortisol is your body’s primary stress hormone, produced by the adrenal glands in response to physical, mental and emotional stress. While it plays a vital role in energy metabolism, immune function and cardiovascular health, both chronically high and chronically low cortisol levels can cause significant health problems — from fatigue, weight gain and sleep disorders to burnout and adrenal exhaustion. This article explains what cortisol is, what happens when it goes wrong, and why regular testing matters.

Obesity is not simply a matter of calories in versus calories out. Chronic stress triggers a cascade of hormonal changes — elevated cortisol, depleted DHEA, disrupted leptin signalling and imbalanced sex hormones — that actively drive visceral fat storage and metabolic dysfunction. This article explains the biochemistry of stress-related weight gain and why understanding your hormone levels is key to breaking the cycle.
