Calculateur de macronutriments

If you already know how many calories you want to consume per day — from another calculation or from a specialist — this calculator shows you directly how to divide them into proteins, carbohydrates, and fats, without repeating the BMR/TDEE calculation.

Goal

How macronutrients are divided

Proteins

Protein intake is calculated proportionally to your body weight and varies depending on the goal: higher in a deficit (muscle mass preservation), higher for muscle mass (protein synthesis), and moderate for maintenance.

Fats

Fats are assigned a minimum intake for hormonal balance (approximately 0.8 g/kg body weight), regardless of the goal — too low a fat intake can affect hormone production.

Carbohydrates

Carbohydrates receive the remainder of the calories left after proteins and fats are accounted for, with a safety minimum for brain function and energy during the day.
