Ketogenic diet poses a significant effect on imbalanced gut microbiota in infants with refractory epilepsyOriginal paper
Karen Pendergrass is a microbiome researcher specializing in microbiome-targeted interventions (MBTIs). She systematically analyzes scientific literature to identify microbial patterns, develop hypotheses, and validate interventions. As the founder of the Microbiome Signatures Database, she bridges microbiome research with clinical practice. In 2012, based on her own investigative research, she became the first documented case of FMT for Celiac Disease, four years before the first published case study.

Researchers compared gut microbiota in 14 infants with refractory epilepsy against 30 healthy infants. They then tested whether one week of ketogenic diet (KD) therapy reshaped the epileptic infants' microbiota.
How was it studied?
Stool samples underwent 16S rDNA sequencing on the Illumina MiSeq platform, with community composition analyzed in MOTHUR and compared across groups using R.
What did they find?
Epileptic infants showed lower microbial diversity and a distinct community structure from healthy infants, dominated by Proteobacteria (24.3%) and Cronobacter (23.3%), which was near-absent in healthy infants. After one week of KD, 64% of epileptic infants had improved seizure control with a 50% average drop in frequency. Proteobacteria fell to 10.8%, Cronobacter dropped to 10.4%, while Bacteroidetes rose from 26.8% to 38.7% and Bacteroides, Prevotella, and Bifidobacterium increased.
Why it matters
The findings suggest ketogenic diet rapidly corrects gut dysbiosis in refractory pediatric epilepsy alongside clinical improvement, supporting the gut-brain axis as a mechanism worth further study.
