What Is a Precision Nutrition Calculator?

A Precision Nutrition Calculator breaks down your daily calorie needs. It tells you how much protein, fat, and carbs you need based on your goal.

Think of it like a GPS for your diet guiding you toward better eating habits without getting lost in complex numbers.

How It Works

The calculator follows a simple three-step process:

1. Enter Your Details – Age, weight, height, and activity level.
2. Choose Your Goal – Lose fat, gain muscle, or maintain weight.
3. Get Your Plan – A custom meal breakdown based on science.

This way, you eat smart without stress.

The Science Behind It

The calculator uses the Mifflin-St Jeor equation to find your Basal Metabolic Rate (BMR). Then, it applies an activity multiplier to get your Total Daily Energy Expenditure (TDEE).

BMR Formula:

For Men: BMR = (10 × weight (kg)) + (6.25 × height (cm)) − (5 × age) + 5

For Women: BMR = (10 × weight (kg)) + (6.25 × height (cm)) − (5 × age) − 161

TDEE Calculation: TDEE = BMR × Activity Level

Activity Levels:

• Sedentary (BMR × 1.2) – Little or no exercise.
• Lightly Active (BMR × 1.375) – Light exercise 1–3 times a week.
• Moderately Active (BMR × 1.55) – Moderate exercise 3–5 times a week.
• Very Active (BMR × 1.725) – Intense workouts 6–7 times a week.
• Extremely Active (BMR × 1.9) – Heavy physical work or sports.

Once TDEE is set, we adjust macros to match your goal.
