ABSTRACT

Clinicians often see overweight patients seeking weight loss, and those seeking weight loss implore advice from nutrition specialists and dietitians on the quantity of calories they should consume each day. To produce weight loss, a negative energy balance needs to exist whereby the patient consumes less energy than he or she expends in a day. The total energy need of a person is expressed as:

Total daily energy needs (TDEE) = BMR + TEF + TEA + energy needed for growth, reproduction, lactation or healing from injury.
