Base Metabolic rate

Hi I estimate my BMR using an online calculator based on height, weight, age, gender.


Is there any setting I can make on my Apple Watch So I can see this BMR over the space of a day?


I wondered whether I could use Total Calories - Active calories = Real BMR? Would it be best to set the activity as Indoor Walk for the whole of the day?

The Apple Watch likely uses the Harris-Benedict Equation which uses your age, height, weight and gender to calculate your Basal Metabolic Rate. The caloric figure from this equation is then added to your Active calories to get your Total Calories.


The Harris–Benedict equations


Men BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5

Women BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161
