Basal Metabolic Rate (BMR) Calculator

Your Basal Metabolic Rate (BMR) is the number of calories your body needs to sustain essential functions — like breathing, circulation, and cell production — while completely at rest. Understanding your BMR is the foundation of any effective nutrition or weight management plan. By knowing how many calories you burn doing nothing, you can better tailor your diet and exercise routine to meet your health goals. Whether you want to lose weight, maintain, or build muscle, your BMR gives you the metabolic baseline you need to make smarter, science-backed decisions about your daily calorie intake.
