About Macro Calculator
How It Works
This calculator divides your daily calorie target into macronutrient grams based on a selected ratio. Standard split: 50% carbs, 20% protein, 30% fat. Alternative: 40% carbs, 30% protein, 30% fat. Carbs and protein provide 4 cal/g, fat provides 9 cal/g.
How to Interpret Results
The breakdown shows how many grams of each macronutrient to eat daily. Adjust ratios based on your goals: higher protein for muscle building, higher fat for keto, higher carbs for endurance athletes.
Health Tips
Choose whole food sources for all macros: complex carbohydrates, lean proteins, and unsaturated fats. Track your intake for a few days to understand your baseline before making adjustments.
Limitations
Individual macronutrient needs vary based on metabolism, activity type, and health conditions. These are general guidelines; personalized plans from a dietitian are more accurate.
