Your Total Daily Energy Expenditure (TDEE) is an estimation of how many calories you burn per day when exercise is taken into account. It is calculated by first figuring out your Basal Metabolic Rate, then multiplying that value by an activity multiplier.Is tdee accurate?
TDEE calculators are fairly accurate, but only to a certain extent. They should give you an estimated value to work with and give you a rough idea where you stand. However, it should be noted that it doesn’t exactly take into account what your body composition is.
