Macronutrients are the three main nutrients your body needs: protein (for muscle building), carbohydrates (for energy), and fats (for hormone production and absorption).

Protein needs vary by goal: 1.2-1.6g/kg for general health, 1.6-2.2g/kg for muscle building, and 2.2-3.0g/kg for weight loss or intense training.

There's no one-size-fits-all ratio. It depends on your goals, activity level, and preferences. Our calculator provides personalized recommendations.
