The recent WHO guideline on acute malnutrition overestimates therapeutic energy requirement

The World Health Organization has recently updated the guideline on the prevention and management of wasting and nutritional oedema (acute malnutrition) in infants and children under 5 years. Apart from differences with regard to the nutritional framework that defines the quantity of energy required as Ready-to-Use Therapeutic Food (RUTF) for the outpatient treatment of severe wasting and/or nutritional oedema, there are also important gaps in the practical guidance. Instead of the recommended energy intake of 150–185 kcal/kg/day, our alternative calculations indicate the requirement to be only 105–120 kcal/kg/day. If true, the implementation of such caloric overfeeding can have adverse consequences. Gaps in practical guidance also need to be addressed, including the timing of transition to home-based diets, maximal duration of therapeutic feeding, especially in non-responders (∼50% in South Asia), and the role of augmented home foods as the primary therapeutic food option.
