Basal Metabolic Rate (BMR) Calculator

Find out how many calories your body burns at rest with our Basal Metabolic Rate (BMR) Calculator. This essential tool helps you determine the energy your body needs to maintain vital functions, such as breathing, circulation, and cell production. Understanding your BMR is the first step toward optimizing your nutrition, fitness, and overall health.

What is Basal Metabolic Rate (BMR)?

Your Basal Metabolic Rate (BMR) is the number of calories your body naturally burns to keep you alive, even when you're at complete rest. It accounts for vital functions like your heartbeat, breathing, and digestion. Knowing your BMR can help you create a personalized meal and workout plan to reach your fitness goals faster.

How to Calculate Your BMR

BMR is calculated using scientifically-backed formulas like the Mifflin-St Jeor and Harris-Benedict equations, which factor in your age, gender, weight, and height. By knowing your BMR, you can estimate your daily calorie needs and adjust your diet accordingly—whether you aim to lose fat, gain muscle, or maintain your current weight.

Why Your BMR Matters in Health & Fitness

Your BMR is a key component in effective weight management. By combining your BMR with your daily activity level, you can determine your Total Daily Energy Expenditure (TDEE), which tells you how many calories you burn daily. Whether your goal is fat loss, muscle gain, or improved performance, understanding your BMR helps you make informed choices about your diet and exercise plan.
