Understand your baseline resting calorie burn.
BMR is commonly estimated with the Mifflin-St Jeor equation: (10 × kg) + (6.25 × cm) − (5 × age) + s, where s is +5 for men and −161 for women.
A 30-year-old, 70 kg, 175 cm man has a BMR of about 1,640 calories/day.
Basal Metabolic Rate is the calories your body burns at complete rest to maintain vital functions like breathing and circulation.
BMR is rest-only energy; TDEE multiplies BMR by an activity factor to include daily movement and exercise.
No. BMR varies with muscle mass and health. Use it as an estimate and consult a professional for clinical needs.
