The Importance of Macro Ratios

The Macro Calculator doesn't just show calories; it provides the **ideal ratio** of Carbohydrates, Protein, and Fat tailored to your goal. This is crucial for preventing muscle loss during weight loss and promoting efficient growth during muscle building. It uses the Mifflin-St Jeor equation for accurate BMR calculation and applies your activity level to determine your **Total Daily Energy Expenditure (TDEE)**.
