Macro Nutrition Calculator
A Macro Nutrition Calculator is a tool designed to help you calculate the ideal amount of protein, carbohydrates, and fats you should consume daily based on your age, weight, height, gender, activity level, and fitness goals.
This calculator ensures that your diet supports muscle growth, fat loss, or weight maintenance, while providing a balanced nutritional intake for optimal health and performance.
How the Macro Nutrition Calculator Works
The calculator first estimates your Total Daily Energy Expenditure (TDEE) — the total calories your body burns in a day. It then breaks down your calories into macronutrients:
- Protein: Supports muscle repair and growth
- Carbohydrates: Provides energy for daily activities and workouts
- Fats: Supports hormone production, brain function, and overall health
Your macro distribution can be adjusted according to your goal: muscle gain, fat loss, or maintenance.
