Estimated result
Complete the personal details.
Mifflin-St Jeor estimates resting energy; TDEE applies a general activity factor and does not measure actual expenditure.
From BMR to daily expenditure
TDEE multiplies Mifflin-St Jeor BMR by a general activity factor to estimate maintenance energy.
Choosing activity
Choose a level representative of a usual week; overstating activity raises the estimate.
