Basal Energy Expenditure - also known as basal metabolic rate (BMR) or (incorrectly) as resting metabolic rate (RMR) - is the minimum number of calories your body needs at rest to fuel its metabolic activity, for example to maintain functions such as heart beat, breathing and temperature. (A kilocalorie, commonly referred to as a calorie, is equivalent to approximately 4.1868 kilojoules.)

Your BMR represents the minimum energy your body needs to maintain vital functions like breathing, cell production, and blood circulation. This baseline helps determine total daily calorie needs when combined with activity levels. Factors like muscle mass, hormones, and overall health can influence your actual BMR. Use this calculation as a starting point for nutrition and exercise planning
