What is TDEE and how is it calculated?

TDEE (Total Daily Energy Expenditure) is the calories you burn daily. We use Mifflin-St Jeor equation for BMR, multiplied by your activity factor (1.2 sedentary to 1.9 very active).

How many calories should I eat to lose weight?

Eat 500 cal below your TDEE to lose ~0.5 kg/week (sustainable). For 1 kg/week, deficit of 1,100 cal/day — requires physician supervision. Our calculator shows both targets.

Is the Mifflin-St Jeor equation accurate?

Yes. The American Dietetic Association considers Mifflin-St Jeor the most accurate BMR prediction equation (within 10% of measured for most adults).

How TDEE is calculated

We use the Mifflin-St Jeor equation (most accurate per American Dietetic Association):

Men: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age + 5
Women: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age − 161

TDEE = BMR × activity multiplier. To lose ~0.5 kg/week, eat 500 cal below TDEE.
