Controlled energy intake with elevated protein intake for Autism Spectrum Disorder

Antipsychotic medications are commonly prescribed in children and adults with ASD (Curtin, Jojic \& Bandini, 2014). But weight gain has been known to be one of the less desirable effects of these medications, increasing one's risk for overweight and obesity. Based on experience in Holland Bloorview's Nutrition Clinic, working with a dietitian to follow specific dietary advice, such as having more protein while keeping the amount of calories the same, may be a possible and useful way to limit weight gain. This study's objective is to evaluate the feasibility (study designs, methods, processes) and acceptability (client/family satisfaction, perceived effectiveness) of a controlled energy diet with elevated protein intake in children and youth with ASD who are currently taking prescribed atypical antipsychotic medication.
