Calculate your TDEE (total daily energy expenditure)

TDEE is the total number of calories your body burns in 24 hours. It's THE foundation for adjusting your diet, whether you want to lose, maintain, or gain weight.

You know your TDEE — now what?

FoodCraft uses your TDEE to automatically adapt every recipe to your needs. No more manual calculations.

What exactly is TDEE?

TDEE is your daily calorie budget. Your body spends calories on three things: basal metabolic rate (breathing, digesting, heart beating — 60 to 75% of your expenditure), the thermic effect of food (digesting what you eat — about 10%), and physical activity (everything that moves — the only part you really control).

Basically, if you eat exactly your TDEE every day, your weight won't move. Eat below it, and you lose. Eat above it, and you gain. It's that simple.

The Mifflin-St Jeor formula

We use the Mifflin-St Jeor formula (1990), recognized as the most reliable by recent studies.

Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5 Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161

Then, we multiply by an activity coefficient: sedentary (×1.2), lightly active (×1.375), moderately active (×1.55), active (×1.725) or very active (×1.9).

Example: a man weighing 80 kg, 180 cm, 30 years old, training 4 times a week → BMR ≈ 1,780 kcal → TDEE ≈ 2,759 kcal/day.

3 common mistakes

Overestimating your activity. This is the #1 trap. Do you do 3 gym sessions but sit for 10 hours a day? You're probably "lightly active," not "moderately active." When in doubt, choose the level below.

Treating TDEE as an exact number. It's an estimate with a margin of ±200 kcal. Use it as a starting point and adjust after 2-3 weeks based on your actual results (weight, energy, performance).

Forgetting to recalculate. Your TDEE changes when your weight, age, or activity changes. Lost 5 kg? Your TDEE has dropped. Recalculate every month.

Questions fréquentes

What's the difference between TDEE and BMR?
BMR only measures what your body burns at complete rest. TDEE includes BMR + digestion + all your physical activity. TDEE is always higher than BMR.
Do I have to eat exactly my TDEE to maintain my weight?
Aim for a range of ±100 kcal around your TDEE. The body isn't a perfect machine — this margin absorbs daily variations.
How many fewer calories to lose weight?
A deficit of 300 to 500 kcal/day allows you to lose 0.3 to 0.5 kg per week. Never go below 1,200 kcal (women) or 1,500 kcal (men) without medical supervision.
Is TDEE reliable for athletes?
The Mifflin-St Jeor formula is reliable for most people. Endurance or high-level athletes may need more precise tracking with a sports nutritionist.
