Your Basal Metabolic Rate (BMR) is the number of calories your body burns while completely at rest — just to keep your heart beating, lungs breathing, and organs functioning. It is the minimum energy your body needs to survive.

What Is Calcolatore MB?
How to Calculate — The Mifflin-St Jeor Equation (1990) Formula
We use the Mifflin-St Jeor equation, which is widely considered the most accurate formula. Men: (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5. Women: (10 × weight in kg) + (6.25 × height in cm) − (5 × age) − 161.
- Input your accurate height, weight, age, and gender.
- Choose metric or imperial units.
- Review your BMR result to understand your baseline calorie needs.

Frequently Asked Questions
Should I eat my BMR in calories?
No, your BMR is the bare minimum to stay alive in a coma. You should eat your TDEE for maintenance, or slightly below TDEE for weight loss.
How can I increase my BMR?
Building muscle mass is the most effective way to increase your BMR, as muscle tissue burns more calories at rest than fat tissue.
Does BMR decrease with age?
Yes, BMR typically decreases by 1-2% per decade after age 20, largely due to a natural loss of muscle mass.
Is BMR the same as resting metabolic rate (RMR)?
They are very similar. BMR is measured under strict laboratory conditions, while RMR is measured under less strict conditions. For most people, the difference is negligible.
