Basal Metabolic Rate

Basal Metabolic Rate (BMR) is the minimum amount of energy your body expends at rest to maintain basic life functions. It represents the calories needed for vital functions such as breathing, blood circulation, cell production, and nutrient processing. This calculation is performed using the Harris-Benedict equation and is based on factors including age, gender, height, and weight. Knowing your BMR is critical for determining your daily calorie needs and maintaining healthy weight management. BMR accounts for 60-75% of your Total Daily Energy Expenditure (TDEE). As muscle mass increases, BMR also increases, while it naturally decreases with age. Hormone balance, sleep quality, stress levels, and genetic factors also affect BMR. Your daily calorie needs (TDEE) are calculated by adding your activity level to your BMR. To lose weight, it's recommended to consume 300-500 calories less than your TDEE, and to gain weight, 300-500 calories more. However, it's important to create a personalized plan with a dietitian or doctor.
