*Basal Metabolic Rate is calculated by the Harris-Benedict equation (created in 1919, but still applicable today).

What is Basal Metabolic Rate (BMR)?

Everybody requires a minimum number of calories to live. This minimum number is called the basal metabolic rate (BMR) and can be influenced by the amount of lean muscle mass a person has. Your BMR is the number of calories your organs need to function while you perform no activity whatsoever.

BMR decreases with age and with the loss of lean body mass. Increasing muscle mass increases BMR.

However, the overall number of calories your body actually uses on a daily basis when you move around is called the Total Daily Energy Expenditure (TDEE). This varies significantly based on your activity level, age, and sex. Generally, men have a higher TDEE than women because they have more muscle mass.
