Nutrition for Disease States Key Words

• There are two subtypes of eating behaviors in anorexia nervosa (AN): the restricting type and the binge eating/purging type. • In addition to effectively treating mood and cognitive disturbances, weight restoration is a central element of AN treatment. • Weight restoration can be divided into two phases: acute stabilization and weight maintenance. • During hospitalization, AN patients tend to require escalating caloric intake in order to maintain a 1–1.5 kg/week weight gain. The caloric intake needs to be increased stepwise over time, to around 60–100 kcal/kg/day, to achieve weight gain. • After returning to a healthy body weight, AN individuals are still energy inefficient and need at least 50–60 kcal/kg/day for weight maintenance (compared to approx. 30 kcal/kg/day for healthy women). • A major long-term goal is to increase the variety of foods consumed. Daily essential macronutrient requirements to maintain weight are 110–140 g of carbohydrates, 15–20 g of essential fatty acids and 1 g of protein per kilogram of body weight in adults and adolescents. © 2015 S.
