This is a phase I trial to see whether patients are able to adhere to a modified, high fat/low carbohydrate diet (the sHFLC + KetoPhyt Diet) with a supplement named KetoPhyt that includes ketones and anti-inflammatory properties.
The classic ketogenic diet (KD) is difficult for patients to adhere to due to its stringent nature. A modified KD has been developed that mimics the glucose lowering, ketone raising effects and the anti-cancer outcomes of the KD.
The sHFLC + KetoPhyt diet will be implemented in a cohort of 10 Glioblastoma patients, who will be trained and provided with sample meal plans so as to maintain their carbohydrate levels up to 33% of total caloric intake. The study will determine whether participants can maintain the diet and the ketogenic state.
This study will also conduct molecular analyses to determine the effect of the diet on the microbiome, inflammatory cytokines, and extracellular vesicle content.
