Macros (Macronutrients)
Definition: The three main nutrients your body needs in large amounts: protein (4 cal/g), carbohydrates (4 cal/g), and fat (9 cal/g). Tracking macros gives you more control than just counting total calories.
Why It Matters
Understanding macros (macronutrients) is essential for making real progress in your fitness journey. Without this knowledge, you risk spinning your wheels — training hard but not seeing the results you deserve.
Callio automatically tracks and applies macros (macronutrients) principles to your training program, so you don't need to be an exercise scientist to benefit from evidence-based programming.
