What Is "Counting Macros"?

Macros — short for macronutrients — are the three core nutrients your body runs on every single day: protein, carbohydrates, and fat. Unlike counting calories alone, tracking macros tells you not just how much you are eating, but what kind of fuel you are giving your body. Protein builds and repairs muscle, carbohydrates power your energy, and fat supports your brain and hormones.

Fiber is often tracked alongside macros because it regulates digestion and keeps blood sugar stable. When you count macros, you move from vague eating habits to a clear, personalized nutrition plan — one that fits your weight, your activity level, and your goals.
