A Protein Carb Fat Calculator is a nutrition tool that calculates your daily intake of the three main macronutrients — protein, carbohydrates, and fats — based on your:

• Age
• Weight
• Height
• Gender
• Activity level
• Fitness goal

This calculator ensures your diet is balanced and optimized for your personal health or fitness goals, whether it’s losing fat, gaining muscle, or maintaining weight.

How the Protein Carb Fat Calculator Works

The calculator first estimates your Total Daily Energy Expenditure (TDEE) — the total calories your body burns in a day. Then it distributes these calories into macronutrients:

• Protein: Supports muscle repair, growth, and overall health
• Carbohydrates: Provides energy for workouts and daily activities
• Fats: Supports hormones, brain function, and cell health

You can adjust the macro ratios depending on your goal, e.g., higher protein for muscle gain or moderate carbs for fat loss.
