Estimate Basal Metabolic Rate (BMR) and daily calorie needs using the Mifflin–St Jeor equation and activity level.
Use accurate height, weight, age, and activity level for the best estimate.
Your body uses energy for basic functions such as breathing, circulation, temperature regulation, and cellular repair. The Basal Metabolic Rate (BMR) is an estimate of how many calories your body would burn each day at rest. The Mifflin–St Jeor equation is widely used to estimate BMR from age, gender, height, and weight.
To estimate total daily energy expenditure, BMR is multiplied by an activity factor that represents typical movement and exercise. The result is a practical estimate of daily calorie requirements for maintaining current weight. For weight loss or weight gain goals, clinicians often adjust daily calories gradually, along with attention to nutrition quality, sleep, and medical considerations.
Individual needs vary based on body composition, medications, health conditions, and lifestyle. For personalized nutrition guidance, consult a registered dietitian or healthcare professional.
