Harris Benedict Calorie Calculator

The Harris-Benedict Equation is a widely-used formula to estimate an individual's basal metabolic rate (BMR), which represents the number of calories your body needs to maintain basic physiological functions at rest.

Developed in 1919 by James Arthur Harris and Francis Gano Benedict, this equation has since been refined and remains a fundamental tool in the fields of nutrition and fitness.


The Harris-Benedict Equation takes into account several factors that influence metabolic rate, including age, gender, weight, and height. It provides separate equations for men and women:


For men: BMR = 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) - (5.677 × age in years)


For women: BMR = 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) - (4.330 × age in years)


Once the BMR is calculated, you can then apply an activity factor to estimate total daily energy expenditure (TDEE), which includes calories burned through physical activity. The activity factor typically ranges from sedentary (little to no exercise) to very active (intense exercise or physical labor).


Using the Harris-Benedict Equation allows individuals to tailor their calorie intake to their specific needs based on factors such as age, gender, weight, height, and activity level.


This information is valuable for anyone looking to manage their weight, whether it be for weight loss, maintenance, or muscle gain.


However, it's important to note that while the Harris-Benedict Equation provides a useful estimate, individual variations in metabolism and other factors may influence actual caloric needs.
