Calorie Calculator
This is TDEE: Mifflin-St Jeor BMR multiplied by a standard activity factor. It is a maintenance estimate, not a weight-loss plan.
How it works
First BMR is computed with Mifflin-St Jeor. Then TDEE = BMR × factor, using the common multipliers 1.2 (sedentary) through 1.9 (very active).
Those factors are rough lifestyle bins, not measured NEAT. The result is an estimated daily energy need to stay at the entered weight, not a medical target.
Formula
BMR = Mifflin-St Jeor TDEE = BMR × activity factor Factors: 1.2, 1.375, 1.55, 1.725, 1.9
Worked examples
Sedentary TDEE
male equation, 80 kg, 180 cm, 30 years, sedentary 1.2 → BMR 1780, TDEE 2136 kcal/day
Useful notes
- For calories of one workout, use calories burned (MET × kg × hours).
- Not medical advice.
FAQ
- Is this how many calories I should eat?
It is an estimate of maintenance burn. A clinician or dietitian sets a target, not this page.
- Which activity factor should I pick?
The description that matches most of your week. People often overestimate activity.
- How is this different from calories burned?
This is a whole-day estimate. Calories burned is one activity’s MET cost.
