Why glioblastoma is studied with keto

In this episode of the Metabolic Mind podcast, Dr. Bret Scher speaks with L.J. Amaral, a registered dietitian, certified in nutrition oncology, and PhD student researcher at Cedars-Sinai, about where ketogenic therapy may fit into cancer care. Together they emphasize a crucial point: in oncology, we’re not just treating the tumor, we’re treating the whole person. The quality of life, physical strength, and day-to-day function of patients matter in prognosis.

L.J. covers:

• How shifting fuel toward ketones may influence metabolism, inflammation, fatigue, and even muscle preservation during treatment.
• Why many tumors crave glucose, and why that matters for dietary strategies.
• The potential of ketogenic therapy used alongside standard of care (surgery/chemo/radiation), with early signals around feasibility, daily living, and patient well-being.
• The real-world nuance of responders vs. non-responders, and why personalized coaching is key.
• How some patients pair fasting windows with treatment, and the practical safeguards to consider.
• What’s next: details on an NIH-funded, multi-center phase 2 trial comparing a ketogenic approach to an American Cancer Society–style diet.

Ketogenic therapy in oncology is early but advancing. If you’re curious about science-backed nutrition strategies that support both treatment and daily life, this conversation is for you.
