Your body runs on different fuels—carbs, fats, and proteins—but here’s the fascinating part: by simply measuring the gases you breathe in and out, we can figure out which fuel your cells are burning right now! This is where the Respiratory Quotient (RQ) comes in. From the perfect chemical balance of glucose oxidation to the oxygen-hungry metabolism of fats, and the slightly off-balance breakdown of proteins, RQ is like a secret code that reveals your metabolic menu. This video unpacks how to calculate RQ, why it changes with different fuels, and its applications.
