Use the Harris-Benedict equation for women: BMR = 10 ⨉ weight (kg) + 6.25 ⨉ height (cm) – 5 ⨉ age (years) – 161. The result is your basal metabolic rate - BMR. You can then multiply it with your Physical Activity Level - PAL - to find your Total Daily Energy Expenditure - TDEE.
What does the Harris-Benedict equation tell us?
The Harris Benedict Equation determines your total daily energy expenditure (calories). The BMR formula uses the variables of height, weight, age and gender to calculate the Basal Metabolic Rate (BMR). This tool then uses the Harris Benedict Equation to determine your total daily energy expenditure (calories).
How accurate is Harris-Benedict equation?
Of the predictive equations tested, the Harris-Benedict equation (mean difference: -14.8 kcal/day, RMSPE: 195.8 kcal/day, mean % difference: 0.1%) was the most accurate and precise, but accuracy in prediction of the equation were only 35.7%.
