The formula

TDEE = BMR × activity factor

BMR comes from Mifflin-St Jeor. The factor scales it up for your activity.

What to watch out for

The factors from 1.2 to 1.9 are a long-standing convention, not a measurement of you. People often overrate their activity, so treat the result as a starting point.

The 2004 FAO/WHO/UNU report on human energy requirements puts physical activity levels for most adults between 1.40 and 2.40, so the 1.2 and 1.375 factors can read low. These figures are for adults and do not apply in pregnancy.

Frequently Asked Questions

What is my TDEE at 30, 175 cm and 75 kg?

For a moderately active man, about 2,633 kcal a day. For a moderately active woman, about 2,376.

Which activity level should I choose?

Count your whole week, including work. A desk job with three gym sessions is usually lightly or moderately active, not very active.

How is TDEE different from BMR?

BMR is energy use at rest. TDEE adds movement, exercise and digesting food.
