BMR (Basal Metabolic Charge): Energy burned at relaxation
-
TEF (Thermic Impact of Meals): Vitality used to digest and course of meals
-
NEAT (Non-Train Exercise Thermogenesis): Actions not labeled as train (e.g., fidgeting, standing)
-
EAT (Train Exercise Thermogenesis): Energy burned throughout structured exercises
“TDEE represents the whole power wants of a person and contains resting metabolic fee, bodily exercise, and diet-induced thermogenesis”
— Kevin Corridor, Nationwide Institutes of Well being

| Time period | Description |
|---|---|
| BMR | The variety of energy your physique burns at full relaxation—simply to remain alive |
| TDEE | The entire day by day calorie wants primarily based on BMR, exercise stage, and meals digestion |
Your BMR is the muse of your TDEE. Consider it as your minimal calorie requirement. A BMR calculator on-line estimates this quantity, and your TDEE builds upon it relying on how energetic you’re.
“Basal metabolic fee accounts for roughly 60–75% of whole day by day power expenditure in sedentary people”
— Mark H. Swanson, Journal of Medical Diet
The way to Calculate Your TDEE
To calculate your TDEE, begin along with your BMR utilizing the Mifflin-St Jeor equation:
For males:
10 × weight (kg) + 6.25 × peak (cm) – 5 × age (years) + 5
For girls:
10 × weight (kg) + 6.25 × peak (cm) – 5 × age (years) – 161
Then multiply your BMR by your exercise stage:
| Exercise Degree | Issue |
|---|---|
| Sedentary (little to no train) | 1.2 |
| Calmly energetic (1–3 days/week) | 1.375 |
| Reasonably energetic (3–5 days/week) | 1.55 |
| Very energetic (6–7 days/week) | 1.725 |
| Additional energetic (day by day intense coaching) | 1.9 |
Or skip the maths and use this TDEE calculator web for a quick, science-backed estimate.
“Multiplying BMR by a bodily exercise stage is a longtime methodology to estimate TDEE in diet and health purposes”
— Krista A. Varady, American Journal of Medical Diet
How Correct Is a TDEE Calculator?
TDEE calculator accuracy relies on the inputs and assumptions used. Whereas instruments like Swolverine’s are extremely efficient for most individuals, a number of variables—like physique composition, hormone ranges, and way of life—can have an effect on precise power expenditure.
Essentially the most dependable TDEE calculators use the Mifflin-St Jeor system, which has been validated in quite a few research:
“The Mifflin-St Jeor equation is taken into account probably the most correct for estimating resting metabolic fee in each wholesome and overweight adults”
— Anne Frankenfield, Journal of the American Dietetic Affiliation
