About TDEE
TDEE is calculated by multiplying your Basal Metabolic Rate (BMR) by an activity factor. BMR is estimated using the Mifflin-St Jeor equation (1990), which is considered more accurate than the older Harris-Benedict formula for most people.
Men: BMR = (10 × kg) + (6.25 × cm) − (5 × age) + 5
Women: BMR = (10 × kg) + (6.25 × cm) − (5 × age) − 161
These figures are estimates. Consult a dietitian or healthcare professional for personalised guidance.
