Parental feeding with lipid-based diet (80% of total caloric requirement were fat, 20% dextrose) or glucose-based diet (100% dextrose)
Number of replicating cells increased in average 32.2% in the glucose-based diet group and decreased by 24.3% in the lipid-based diet but the results were not statistically significant
KD (calories: 77% fat, 8% carbohydrates, and 15% protein) for 3–9 months in combination with temozolomide (TMZ) or chemoradiation
Four patients were alive at median follow-up of 14 months; one of the four patients was under carbohydrate-restricted KD (4.5% carbohydrates) post radiation and TMZ treatment and had no recurrence after 12 months from treatment; the other three had recurrence and started alternative chemotherapy treatments
KD (70% MCT supplemented with β-hydroxybutyrate (BHB))
Increased body weight after 7 days (∼2 kg), presence of ketosis already after 24 h in association with a reduction of blood glucose, pyruvate, and lactate levels
