What is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions while at complete rest. This includes breathing, circulating blood, cell production, nutrient processing, and maintaining body temperature.
How is BMR Calculated?
This calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate formulas for estimating BMR. The formula takes into account your weight, height, age, and gender.
BMR vs. TDEE
Your Total Daily Energy Expenditure (TDEE) is your BMR multiplied by an activity factor. TDEE represents the total number of calories you burn in a day including all activities.
Using Your BMR Results
Your BMR can help you establish a baseline for calorie needs. For weight loss, consume fewer calories than your TDEE; for weight gain, consume more. A safe calorie deficit or surplus is typically 500 calories per day.
