Casey Means
"Muscle contraction is miraculous medicine."
Dr. Casey Means is a physician and metabolic health advocate who left traditional surgical training to focus on the root causes of chronic disease. In Good Energy, she argues that dysfunction at the cellular and metabolic level — driven largely by diet, movement, and environmental toxins — underlies most modern chronic illness, and lays out biomarkers and lifestyle changes to restore what she calls 'good energy.'

Key Ideas & Recurring Themes
Metabolic Dysfunction Underlies Chronic Disease
Means argues that seemingly unrelated conditions — from depression to heart disease — often trace back to shared metabolic and mitochondrial dysfunction, making metabolic health a root-cause lever for overall wellbeing.
Muscle Contraction as Medicine
Frequent, low-intensity movement throughout the day produces meaningfully different physiology than a single intense workout block — regular muscle contraction is framed as a metabolic intervention in itself.
Track Your Biomarkers
Means recommends tracking metrics like the triglyceride-to-HDL ratio and fasting insulin as early warning signs of metabolic dysfunction, well before standard annual physicals would catch a problem.
Notable Quotes
"Muscle contraction is miraculous medicine. The reason that moving regularly is important is because a body in which muscles are contracting frequently is experiencing totally different physiology than a body that's sedentary most of the day."— Good Energy
"Refined added sugar causes astronomically more deaths and disability per year than COVID-19 and fentanyl overdoses combined. We need to see refined added sugar for what it is: an addictive, dangerous drug."— Good Energy
"We can't have a healthy society without well-functioning humans. We can't have well-functioning humans without well-functioning cells."— Good Energy
