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 ...

 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...

 Life with Metabolism VS Replication

It is logically possible to postulate organisms composed of pure hardware, capable of metabolism but incapable of replication. It is possible to postulate organisms composed of pure software, capable of replication but incapable of metabolism. And if the functions of life are separated in this fashion, it is to be expected that the latter type of organism will become an obligatory parasite upon the former. This logical analysis of the functions of life helps to explain and to correct the bias...

 Why You Lose Weight While You Sleep

Here's a simple question: Why do you weigh more when you go to sleep than when you wake up? Because you do... You can check this yourself. Somehow, while doing absolutely nothing all night but sleep, you will wake up lighter. [...] All night long, every time you breathe out, a bunch of carbon atoms, formerly inside your body, leave your insides and take off into the night air. You breathe in oxygen, O2. You breathe out carbon dioxide, (two oxygen atoms with a carbon atom attached), so there...
