What is the Mifflin-St Jeor Equation?

The Mifflin-St Jeor equation, developed in 1990, is currently considered the most accurate formula for calculating Basal Metabolic Rate (BMR). It is recommended by the American Dietetic Association.

The Formula

๐Ÿ‘จ Male: BMR = 10ร—weight(kg) + 6.25ร—height(cm) - 5ร—age + 5

๐Ÿ‘ฉ Female: BMR = 10ร—weight(kg) + 6.25ร—height(cm) - 5ร—age - 161

What is TDEE?

TDEE (Total Daily Energy Expenditure) is the total number of calories you burn each day. It's calculated by multiplying your BMR by an activity factor.

Activity Multipliers

Activity LevelMultiplierDescription

Light (exercise 1-3 days/week)1.375Light exercise 1-3 days/week
Moderate (exercise 3-5 days/week)1.55Moderate exercise 3-5 days/week

Healthy Eating Tips

  • โœ“Avoid extreme calorie restriction (maintain at least 80% of TDEE)
  • โœ“Get enough protein (1.6-2.2g per kg of body weight)
  • โœ“Stay hydrated (at least 2L of water daily)
  • โœ“Eat fiber-rich foods
