Calculate your BMR using the Mifflin-St Jeor Equation and understand your calorie needs at rest
BMR is calculated using the Mifflin-St Jeor Equation
This value represents how many calories your body needs per day at rest.
Find answers to common questions about BMR and how it affects your body and weight goals.
Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at rest.
Knowing your BMR helps you determine how many calories you should consume to maintain, lose, or gain weight effectively.
No, BMR varies based on several factors including age, gender, weight, height, and muscle mass.
Yes, BMR generally decreases with age due to loss of muscle mass and hormonal changes.
You can check it periodically, especially if your weight, muscle mass, or activity level changes significantly.
Build more muscle, stay active, eat protein, get sleep, drink water, and avoid crash diets that slow your metabolism.
For men: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age + 5
For women: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age – 161
Or simply use our calculator above.
A “good” BMR depends on body type. Average is 1200–1800 calories/day but varies by person.
It’s crucial for understanding your daily calorie needs and managing weight and diet plans effectively.
As you age, your BMR declines due to muscle loss and hormonal changes.
BMR determines calorie needs. To lose weight, eat fewer calories than your total daily expenditure (TDEE).
BMR is the base calories at rest. TDEE includes all daily activity and gives a more complete calorie requirement.
