Anorexia nervosa disease is an eating deficiency that occurs around 1 per 100 individuals. The present study was conducted to assess the effects of malnutrition (animal anorexia nervosa models) via removing certain elements from food on liver functions and behaviours of female rats. Eighteen Females of rats were divided into three groups: Control, in which food intake quantity was 25 g /day, moderately food-restricted Group, in which food intake quantity was 15 g /day, and severe food-restricted Group, in which food intake quantity was 5 g /day, for 90 days. Physiological parameters, liver histopathological analysis, and the behaviour measurement by multiple T maze tests were examined. All food-restricted groups observed a significant increase (p<0.05) in aminotransferase, Malondialdehyde and lactate dehydrogenase levels. Antioxidant activity, acid phosphatase, hepatic protein, glycogen and serotonin levels were significantly (p<0.05) decreased in all food-restricted groups. The hyperactivity behaviour appeared as a feature of restricted rats. Histopathological examinations indicated a marked alteration in the hepatocyte with features of autophagy in the restricted Group. Food-restriction (animal anorexia nervosa model) in rats caused disorders in hepatic aminotransferase and serotonin levels and antioxidant activity in addition to hyperactivity behaviours with changes in the liver histological structure in the restricted Group. The study focused on the effect deficiency in essential nutrients needed by the body may have side effects on liver functions and behavioural activity of the animals linked with food searching was measured by multiple T maze tests.
