This BMR Calculator will work out your Basal Metabolic Rate (BMR) with just the click of a button!
All you have to do to calculate your BMR is enter in your weight, height and sex. This tool functions as a BMR calculator for women and men. Using it when attempting to lose weight makes sense as body fat, activity level, and lean body mass are all important variables to consider when measuring your BMR.
