🔥 What Are Macros and Why Do They Matter?
Macros (macronutrients) refer to the three primary nutrients your body needs in large amounts:
- Protein 🍗 - Essential for muscle repair and growth.
- Carbohydrates 🍞 - Your body's primary energy source.
- Fats 🥑 - Crucial for hormone regulation and overall health.
Tracking macros helps you create a personalized diet plan for fat loss, muscle gain, or overall health improvement.
🏋️ How to Use the MacroMastr Macro Calculator
Our macro calculator provides a customized macronutrient breakdown based on:
