Question 1

What is a macro calculator?

Accepted Answer

A macro calculator determines your personalized daily targets for protein, carbohydrates, and fat based on your body stats, activity level, and fitness goal. Unlike a simple calorie calculator, it breaks your total calories into the three macronutrients that fuel muscle, energy, and hormone health.

Question 2

How do I calculate my macros?

Accepted Answer

Enter your gender, age, weight, height, activity level, goal (lose fat, maintain, or build muscle), and preferred diet style into the calculator above. It uses the Mifflin–St Jeor equation to estimate your BMR and TDEE, then splits your calories into protein, carb, and fat targets.

Question 3

How do I calculate macros for weight loss?

Accepted Answer

Select 'Lose Fat' as your goal. The calculator applies a 500-calorie deficit to your TDEE while keeping protein high to preserve lean muscle. A typical weight-loss macro split prioritizes protein at 2.2g per kg of bodyweight, then fills remaining calories with carbs and fats based on your diet style.

Question 4

How do I calculate macros for muscle gain?

Accepted Answer

Select 'Build' as your goal. The calculator adds a 300-calorie surplus to your TDEE and sets protein at 2.2. 2.6g per kg of bodyweight to support hypertrophy. The remaining calories are divided between carbs (for training fuel) and fats (for hormone production).

Question 5

What is the Mifflin–St Jeor equation?

Accepted Answer

The Mifflin–St Jeor equation is the most accurate scientifically validated formula for estimating Basal Metabolic Rate (BMR). It calculates the calories your body burns at rest using your weight, height, age, and gender. This calculator then multiplies BMR by an activity factor to find your Total Daily Energy Expenditure (TDEE).

Question 6

What is the difference between a macro calculator and a calorie calculator?

Accepted Answer
