metabolic flexibility

Metabolic flexibility is the body's ability to efficiently switch between burning different fuel sources, mainly carbohydrates and fats, depending on availability and energy needs. When flexible, your body can adapt to various activities—using carbs during intense exercise and fats during rest or fasting—optimizing energy use. This adaptability supports overall health, weight management, and metabolic function. Limited flexibility might lead to issues like insulin resistance or weight gain, as the body struggles to adjust fuel sources effectively. Essentially, metabolic flexibility reflects how well your metabolism can respond to changing energy demands and fuel supplies.
