Adult Resting Energy Estimate
Estimate resting energy with the Mifflin–St Jeor equation for adults aged 18–100. The sex parameter selects the equation coefficient, not gender identity.
How to use Adult Resting Energy Estimate
- Enter “Weight kg (20–400)”, using the units and limits shown in its label.
- Enter “Height cm (100–250)”, using the units and limits shown in its label.
- Enter “Age years (18–100)”, using the units and limits shown in its label.
- Choose the appropriate “Equation coefficient” option for your task.

Method & assumptions
Estimated kcal/day = 10×kg + 6.25×cm − 5×age + sex coefficient.
Worked example
70 kg, 175 cm, age 30, male coefficient gives 1648.75 kcal/day.

Questions, answered
Is this my recommended food intake?
No. It estimates resting expenditure, not full-day needs, and may not suit pregnancy, illness, or unusual body composition.
