Understanding the Harris-Benedict formula
The James Smith Calculator estimates your Basal Metabolic Rate (BMR). It uses the revised Harris-Benedict formula. BMR is the number of calories your body needs while at rest.
For men: BMR = 66 + (6.23 × weight in pounds) + (12.7 × height in inches) − (6.8 × age)
For women: BMR = 655 + (4.35 × weight in pounds) + (4.7 × height in inches) − (4.7 × age)
Example: A 30-year-old woman who is 5’6″ and weighs 150 lbs has a BMR of approximately 1,434 calories. This tells her how many calories her body needs each day at rest, before adding activity.
