Brief Summary
This study will assess the effectiveness of the ketogenic diet (high-fat, low-carbohydrate, and moderate protein) in treating autism spectrum disorder (ASD). Three study groups will be comprised of children (2-21 years of age) based on whether or not they have ASD and receive the ketogenic diet - ASD/ketogenic diet, ASD/non-ketogenic diet, and non-ASD/non-ketogenic diet.

Outcome Measures
Primary Outcomes (1)
Change from baseline in core symptoms of ASD
Assess core autistic symptoms through review/analysis of responses to the following measurement instruments: Autism Diagnostic Observation Schedule - Second Edition (ADOS-2); Asperger Syndrome Diagnostic Scale (ASDS); Childhood Autism Rating Scale (CARS-2); Gilliam Autism Rating Scale (GARS-3); Social Responsiveness Scale - Second Edition (SRS-2); Diagnostic and Statistical Manual IV Text Revision (DSM-IV-TR) and DSM-V ASD criteria; standardized intelligence tests (if available, administered by child's school); and Vanderbilt ADHD Diagnostic Teacher Rating Scale Forms (Vanderbilt).
Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)
Secondary Outcomes (7)
Change from baseline in the number of medications used for ASD management
Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)
Change from baseline in the dosage of medications used for ASD management
Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)
Change from baseline in the number of lab tests ordered for ASD management
Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)
Change from baseline in the number of emergency room or hospital visits for ASD management
Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)
Change from baseline in subject/family satisfaction with the ketogenic diet
Pre- and post-ketogenic diet intervention (at baseline, and after three and six months on the ketogenic diet)

Study Arms (3)
ASD/KD
EXPERIMENTALChildren (2-21 years of age) diagnosed with autism spectrum disorder (ASD) will receive the ketogenic diet (KD) intervention.
ASD/non-KD
ACTIVE COMPARATORChildren (2-21 years of age) diagnosed with autism spectrum disorder (ASD) will not receive the ketogenic diet (KD) intervention.
non-ASD/non-KD
ACTIVE COMPARATORTypically developing children (2-21 years of age) diagnosed as not having autism spectrum disorder (ASD) will not receive the ketogenic diet (KD) intervention.
