How is it calculated?
Mifflin–St Jeor estimates resting expenditure from weight, height, age and sex. Katch–McArdle uses fat-free mass. The activity factor is approximate: do not add exercise again. Scenarios are not weight-loss or weight-gain advice.
Mifflin: 10W + 6.25H − 5A + (5 / −161); Katch: 370 + 21.6 × FFM; TDEE = resting × activityIs this medical advice?
