Anorexia Nervoza (AN) is a psychiatric disease resulting in pathological weight loss due to nutritional restrictions and reduction in dietary energy. In individuals with this disease, the medical nutrition treatment is of great importance. In the application of nutritional therapy in anorexia nerve patients, it is important to determine the right energy requirement to protect the patient from serious complications such as the "refeeding" syndrome that may arise due to nutrition. Rest energy consumption (DEH), an important component of total energy consumption, can be measured by indirect calorometer, which is a reference method in the measurement of DEH. If transportation to the indirect calorometer is not possible, the estimated equations can be used in the clinic to determine the energy consumption. These equations include equations developed in various research; such as Harris-Benedict, Mifflin, WHO/FAO/UNU, Müller, Owen, and Schofield. According to the results of the study; Harris-Benedict equality predicts DEH more than the reference method. Schebendach equality appears to be applied in AN-like adolescents and Müller equality gives acceptable results in the measurement of DEH. In addition, the body mass index (BMI) in patients between 16-18,5 kg/m2 gives good results in predicting the laser equality of DEH. In patients with a BMI below 16 kg/m2, the equations between Huang and De Lorenzo that give the correct estimate of DEH are equal. As a result, the calculating method of DEH in determining the energy needs in the dietary treatment of AN patients today is indirectly calorimetred. In cases where the indirect calorometer cannot be reached according to the patient's BMI, the use of high equations of accuracy rate can facilitate the determination of the energy demand.
