How This BMR Calculator Works
This calculator uses a common equation to estimate how many calories your body burns each day at complete rest. It takes into account your gender, age, weight, and height.
Why BMR Matters
Knowing your BMR can help you understand your baseline calorie needs. It is often used as the starting point for calorie, macro, and weight loss calculations.
BMR vs TDEE
BMR is the number of calories your body burns at rest. TDEE includes your daily activity, exercise, and movement. So TDEE is usually higher than BMR.
Frequently Asked Questions
What is a normal BMR?
There is no single normal BMR because it depends on body size, age, gender, and height.
Does age affect BMR?
Yes. BMR usually becomes lower with age because muscle mass often decreases over time.
Can I use BMR for weight loss?
Yes, but BMR alone is not enough. For weight loss planning, people usually use TDEE and then create a calorie deficit.
