Chronic Elevated Cortisol Causes Muscle Wasting Similar to Cushing's Disease

Building strength and muscle mass: optimize training & nutrition for longevity (AMA #71 rebroadcast)
"More cortisol, less muscle. Chronically elevated levels of cortisol are actually catabolic to muscle. We see the most extreme example of this when we look at a patient with Cushing's disease or Cushing's syndrome where they actually experience muscle wasting due to the hypercortisolemia. But for many of us listening who don't have Cushing's disease, but who still probably walk around with too much cortisol, it's definitely hurting us."
Attia explains that chronic stress-induced cortisol elevation produces muscle-wasting effects similar to the medical condition Cushing's disease, even at subclinical levels. Unlike testosterone supplementation, there's no simple pharmaceutical fix for high cortisol—individuals must address lifestyle stress factors. This positions stress management as equally critical to muscle maintenance as training and nutrition.
