Abstract
Anorexia nervosa (AN) is a complex disorder of unknown etiology. It is characterized by dietary restriction and severe malnutrition, as well as by many psychological disturbances. The awareness of AN has risen in the last decades among scientists of different disciplines. It is undeniable that ΑΝ has the highest mortality rate of all mental disorders. There is no doubt that ΑΝ has the highest mortality rate of all mental disorders. In the treatment of this disorder, nutritional recovery and weight restoration are premature goals. It seems that nutritional status influences both the effectiveness of an intervention’s programs and the general health of this population, and it is often the result of interrelated factors. Experts should consider that while weight restoration is a critical part of AN treatment, changes in body composition, energy, and nutrient needs during weight recovery as well as weight maintenance should also be taken into consideration. This chapter attempts to describe suggested biomarkers related to energy requirements as a means of selecting the most appropriate and reliable methods of nutritional assessment.
