Comment Fonctionne le Calcul
Calories de maintenance sont calculées en utilisant BMR (Taux Métabolique Basal) multiplié par niveau d'activité pour obtenir TDEE (Dépense Énergétique Totale Quotidienne). BMR représente calories nécessaires au repos, tandis que TDEE inclut toutes activités quotidiennes. Harris-Benedict et Mifflin-St Jeor utilisent poids, taille, âge et genre. Katch-McArdle utilise masse corporelle maigre pour précision supérieure. Multiplicateurs d'activité vont de 1.2 (sédentaire) à 2.0+ (extrêmement actif).
Scénarios d'Exemple
Un homme de 30 ans modérément actif pesant 75kg et mesurant 175cm a besoin environ 2,650 calories de maintenance quotidiennes utilisant méthode Mifflin-St Jeor, avec 1,676 calories BMR brûlées au repos
Une femme de 25 ans sédentaire pesant 60kg et mesurant 160cm a besoin environ 1,817 calories de maintenance quotidiennes, avec espace significatif pour perte de poids si souhaité
Un athlète homme de 28 ans très actif pesant 80kg avec 12% graisse corporelle a besoin environ 3,147 calories de maintenance quotidiennes utilisant méthode Katch-McArdle pour précision supérieure

Frequently Asked Questions
What's the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is the number of calories your body burns at rest to maintain basic physiological functions. TDEE (Total Daily Energy Expenditure) includes BMR plus calories burned through all daily activities, exercise, and digestion. TDEE represents your total maintenance calories.
Which BMR calculation method is most accurate?
Katch-McArdle is generally most accurate if you know your body fat percentage, followed by Mifflin-St Jeor (most commonly used), then Harris-Benedict (older formula). Accuracy depends on having correct input measurements. All methods provide reasonable estimates for most people.
How do I use maintenance calories for weight loss?
For sustainable weight loss, subtract 250-500 calories from your maintenance level daily. This creates a moderate deficit that allows 0.5-1 lb weekly loss while preserving muscle mass. Combine with resistance training and adequate protein intake. Avoid larger deficits which can slow metabolism.
Why do athletes need more calories?
Athletes have higher TDEE due to increased muscle mass, training volume, and recovery needs. Very active individuals may need 2,500-4,000+ calories daily depending on sport and training intensity. Endurance athletes often need additional carbohydrates for glycogen storage.
Does metabolism slow down with age?
Yes, BMR naturally decreases about 1-2% per decade after age 20 due to muscle loss and hormonal changes. Regular resistance training and maintaining lean mass can help preserve metabolic rate. Older adults may need fewer maintenance calories but should focus on nutrient density.
Can I eat below my BMR for weight loss?
Eating below BMR (starvation dieting) is not recommended as it can slow metabolism, cause muscle loss, and lead to rebound weight gain. Aim for moderate deficits (250-500 calories below TDEE) for sustainable results. Focus on nutrient-dense foods and resistance training to preserve muscle.
How does body composition affect calorie needs?
Muscle tissue burns more calories than fat tissue, so individuals with higher muscle mass have higher BMR. That's why athletes and those who resistance train have higher maintenance calories. Body fat percentage also affects which calculation method is most accurate.
Should I adjust calories based on actual results?
Yes, always! Use calculator results as starting points, then track weight changes over 2-4 weeks. If losing slower than expected, reduce calories by another 100-200. If losing too fast or feeling fatigued, increase calories. Individual responses vary based on metabolism and activity level.
