Whether your goal is weight loss, muscle gain, or overall wellness, understanding your macros is crucial. This calculator takes the guesswork out of meal planning and ensures your diet aligns with your fitness objectives.

How the Precision Nutrition Macro Calculator Works

The macro calculator uses the Mifflin-St Jeor Equation to estimate your Basal Metabolic Rate (BMR), which is then adjusted based on your activity level to determine total daily caloric needs. It then calculates recommended protein, carbohydrate, and fat intake tailored to your weight, height, age, gender, and activity level.

3. Input Your Age
   Enter your age in years to adjust the calculation for metabolism changes over time.
4. Select Your Gender

Practical Example

Suppose you are a 30-year-old female weighing 65 kg, 170 cm tall, with a moderate activity level. Using the macro calculator:

• Calories: ~2,000 kcal/day
• Protein: 130 g/day
• Fat: 55 g/day
