Mifflin-St Jeor Equation

Men: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5. Women: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161.

Frequently Asked Questions

What is the difference between BMR and TDEE?

BMR is the energy your body needs just to survive (breathing, circulation). TDEE includes BMR plus the calories you burn through movement and exercise.

How much should I eat to lose weight?

A common recommendation is to eat about 500 calories below your TDEE to lose approximately 1 lb per week.
