La Science du Calcul

Notre calculateur bascule dynamiquement entre les équations <strong>Mifflin-St Jeor</strong> et <strong>Katch-McArdle</strong> pour une précision standard 2026. Nous priorisons la masse maigre (LBM) si le taux de graisse est fourni.

Standard : Mifflin-St Jeor
Male: (10 × kg) + (6.25 × cm) - (5 × age) + 5 Female: (10 × kg) + (6.25 × cm) - (5 × age) - 161
Avancé : Katch-McArdle (Utilisé si le % de graisse est saisi) BMR = 370 + (21.6 × LBMkg)

1. Taux de Base (BMR)

L'énergie de base requise pour les fonctions vitales. Katch-McArdle est utilisé pour plus de précision si le taux de graisse est connu.

2. Effet Thermique

Nous appliquons votre multiplicateur d'activité (PAL) pour tenir compte du mouvement et de l'effet thermique de la digestion.

3. Calibrage de l'Objectif

Enfin, nous appliquons un déficit de <strong>-500 kcal</strong> pour la perte de poids ou un surplus de <strong>+300 kcal</strong> pour l'hypertrophie musculaire.

Comprendre Votre Bilan Énergétique

Qu'est-ce que le TDEE ?

TDEE signifie <strong>Dépense Énergétique Quotidienne Totale</strong>. C'est le nombre total de calories brûlées en 24h, incluant l'exercice, la digestion et les fonctions vitales (BMR).

Pourquoi l'équation Mifflin-St Jeor ?

En 2026, cela reste la formule évaluée par les pairs la plus fiable pour estimer le métabolisme sans équipement de laboratoire coûteux.

L’évolution de l’anesthésie : précision et sécurité en 2026

Une nouvelle ère pour les soins intensifs

En 2026, la communauté mondiale de l'anesthésiologie s'oriente vers la « sédation de précision », en utilisant la neurosurveillance en temps réel pour adapter l'administration de médicaments à l'état cérébral du patient.

Jalons de la médecine de récupération

Les progrès de la médecine de récupération en soins intensifs permettent désormais d'initier un soutien de soins intensifs de haut niveau par voie aérienne et routière. transport.

Aperçu officiel

Le congrès 2026 du Collège des anesthésiologistes d'Irlande met en avant ces systèmes de surveillance « intelligents » comme la nouvelle norme de soins.

Summary: Découvrez les principaux points à retenir du congrès annuel 2026 du CAI, mettant en lumière l’avenir de l’anesthésiologie et de la médecine de récupération en soins intensifs.

How your energy is spent

Your Total Daily Energy Expenditure isn't just exercise. It's a combination of BMR (60-70%), NEAT (Non-exercise activity), TEF (Digestion), and EAT (Planned workouts).

Metabolic Intelligence FAQ

Everything you need to know about TDEE, Macros, and 2026 Metabolic Science.

What is TDEE and why does it matter?
TDEE stands for Total Daily Energy Expenditure. It represents the total calories you burn in a day. Understanding this is the first step toward any body composition goal.
What is the difference between BMR and TDEE?
BMR is the energy your body needs at rest for vital functions. TDEE is your BMR plus the energy used for physical activity and digestion.
How accurate is the Mifflin-St Jeor equation?
In 2026, it remains the gold standard for metabolic estimation, proven to be within 10% accuracy for most healthy adults.
Why does biological sex affect the calculation?
Sex influences BMR primarily due to muscle mass. Males generally have higher muscle mass, which is more metabolically active.
Does age really slow down metabolism?
Metabolism naturally slows by 1-2% per decade after age 20, largely due to the gradual loss of muscle mass.
What counts as 'Sedentary' activity?
Sedentary describes a lifestyle with little to no intentional exercise and a desk-bound job. Most office workers fall here.
How do I choose the right activity level?
Be conservative. If you work out 3x a week but sit the rest of the day, 'Lightly Active' is usually more accurate than 'Moderate'.
Should I eat back the calories I burn during exercise?
Generally, no. Your TDEE result already includes your activity level, so eating back 'burned' calories often leads to a surplus.
How many calories for a 70kg sedentary worker?
A 70kg sedentary adult typically requires between 1,800 and 2,100 calories for maintenance, depending on age.
Does walking 10,000 steps change my activity level?
Yes, consistently hitting 10,000 steps daily usually moves an individual from 'Sedentary' to 'Lightly Active'.
What is the best macro split for weight loss?
A balanced 30% Protein, 30% Fat, and 40% Carbohydrate split is a sustainable starting point for fat loss.
How much protein do I really need?
Our calculation targets 1.6g to 2.2g of protein per kilogram of body weight, optimal for muscle preservation.
Can I lose weight without counting macros?
Yes, as long as you are in a calorie deficit. However, macros ensure that weight loss comes from fat, not muscle.
Why are some fats set at 30%?
Dietary fats are essential for hormone production. Dropping below 20% for long periods can disrupt metabolic health.
Are carbs bad for weight loss?
No. Carbs are your body's preferred energy source. As long as you are in a deficit, carbs will not prevent weight loss.
Why am I not losing weight even if I eat below my TDEE?
Common causes include underestimating portions, overestimating activity, or temporary water retention.
How often should I recalculate my TDEE?
Recalculate your metrics every time you lose or gain 3-5kg, as your metabolic needs change with mass.
Does drinking water increase TDEE?
Water can slightly increase metabolic rate through thermogenesis and is vital for fat oxidation processes.
What is 'Starvation Mode'?
A metabolic adaptation where the body slightly slows expenditure during extreme deficits, but it doesn't stop weight loss.
Can I use this for kids or teenagers?
No. This formula is designed for adults (18+). Children have unique growth-related energy needs.

Metabolic Glossary

BMR (Basal Metabolic Rate)

The number of calories your body burns just to stay alive (breathing, circulating blood) while at total rest.

NEAT

Non-Exercise Activity Thermogenesis. This includes calories burned walking to your car, typing, or fidgeting.

Common Questions

Is Katch-McArdle better?

If you know your body fat percentage, yes. It is more accurate for muscular individuals as muscle is more metabolically active than fat.

How often should I recalculate?

Ideally every 5–10 lbs of weight change, as your new mass requires different energy levels.

More Frequently Asked Questions In New York City

How accurate is this TDEE calculation?

While the Mifflin-St Jeor and Katch-McArdle formulas are the gold standard, no calculator is 100% accurate. External factors like sleep quality, stress (cortisol), and individual gut microbiome can shift your metabolic rate by 10-15%.

What is the best macro split for weight loss?

For weight loss, a high-protein approach is recommended (approx. 30-35% of total calories). This helps preserve lean muscle mass while in a calorie deficit.
