Estimated resting energy expenditure
How it works
Mifflin–St Jeor: 10W + 6.25H − 5A + s; s = +5 / −161
Using the calculator
Enter: Sex used in the equation · Age in completed years (18+) · Body weight · Body height. Calculation: Mifflin–St Jeor: 10W + 6.25H − 5A + s; s = +5 / −161.
Worked input and result
Example: Sex used in the equation = Male (+5); Age in completed years (18+) = 30; Body weight = 80 kg; Body height = 180 cm. Result: Estimated resting energy expenditure = 1,780 kcal/day.
Understanding the result
Uses Mifflin–St Jeor: 10 × weight (kg) + 6.25 × height (cm) − 5 × age + 5 for males or −161 for females. Estimates resting expenditure, not a daily food target. Individual expenditure may differ; not for children or pregnancy.
Basal metabolic rate estimates resting energy use. Actual daily needs depend on activity and personal factors; BMR is not a daily calorie target by itself.
