Estimated total daily energy expenditure (TDEE)

Mifflin–St Jeor estimates resting expenditure. TDEE = that estimate × selected activity factor. −20% and +15% are author-defined deficit and surplus scenarios.

Result

Basal metabolic rate (BMR)
1699 kcal/day

Energy at rest: breathing, circulation and organ function

Total daily energy expenditure (TDEE)
2633 kcal/day

BMR × activity factor 1.550

Weight loss
2106 kcal/day

A 20% deficit from TDEE

Weight maintenance
2633 kcal/day

Intake equals expenditure

Weight gain
3028 kcal/day

A 15% surplus over TDEE

For adults. Activity factors are approximations, not measured PAL. The equation does not determine individual needs or a safe deficit; prediction error does not prove a metabolic disorder.

How it is calculated

Mifflin–St Jeor estimates resting expenditure. TDEE = that estimate × selected activity factor. −20% and +15% are author-defined deficit and surplus scenarios.

Formula

BMR (men) = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5; BMR (women) = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161; TDEE = BMR × activity factor

Limits of the method

For adults. Activity factors are approximations, not measured PAL. The equation does not determine individual needs or a safe deficit; prediction error does not prove a metabolic disorder.
