A Brief Primer on TEE, BMR, RMR, and the Thermic Effect o...

When discussing human metabolism, four concepts often arise: total daily energy expenditure (TEE), basal metabolic rate (BMR), resting metabolic rate (RMR), and the thermic effect of food (TEF). Energy expenditure science can feel alphabet-soup–heavy, so let’s clarify these key terms in more depth: Total Daily Energy Expenditure (TEE): TEE is the total energy (calories) you burn in 24 hours. It encompasses every energy-demanding process in your body—from keeping your heart pumping to...

 What Can You Do to Keep Your Metabolism High?

Although metabolism does tend to shift with age, decades of research demonstrate that such changes are not set in stone. By regularly checking the key biomarkers that reveal your muscle mass, mitochondrial health, thyroid function, inflammatory status, and glucose regulation, you can detect subtle signs of slowdown and respond with precisely targeted interventions. Below are several evidence-based approaches that, when integrated thoughtfully, can preserve—and even enhance—your metabolic ...
