A recent study suggests that a tailored ketogenic diet, combined with rehabilitation, may accelerate improvements in autism symptoms among young children, though further research is needed to confirm these findings.
A modified ketogenic diet may ease some short-term autism symptoms when paired with rehabilitation, according to a randomised trial published in BMC Pediatrics. In the study, 62 young children with autism spectrum disorder were split evenly between a diet-plus-rehabilitation group and a rehabilitation-only group, and both sets of children took part in the same two-month rehabilitation programme.
The children in the diet group received a tailored ketogenic plan that used ketogenic nutritional powder and a structured meal approach, with lunch provided at the hospital on training days and the rest of the diet overseen by caregivers at home. Children in both groups improved over the study period, but the group given the modified ketogenic diet recorded larger reductions in scores on the Autism Behaviour Checklist and the Childhood Autism Rating Scale, two commonly used measures of autism-related behaviour and severity, the journal article reported.
The findings add to a small body of research exploring whether metabolic interventions could complement standard autism care. Earlier work, including a 2018 study in Physiology & Behavior and a 2019 pilot study in the Journal of Proteome Research, also suggested that modified ketogenic diets may influence behaviour and metabolism in some children with autism. Still, the evidence remains limited, and the authors of the BMC Pediatrics paper said their results may not apply broadly to children with different levels of ability or forms of autism because the trial did not systematically assess epilepsy, developmental stage, cognitive profile or functional subtype.
For parents and carers, the study is best read as an early signal rather than a settled answer. The results suggest that, in a closely supervised setting, a modified ketogenic diet may produce faster symptom improvement than rehabilitation alone, but the research was small, short-term and narrowly focused. Larger and longer studies will be needed before the approach can be judged against established treatments or recommended more widely.
