Description of intervention(s) / exposure
Other interventions - Standard Treatment Plus Metabolic Therapy Program

Experimental: Standard treatment in conjunction with MTP - Standard:

* Concurrent chemoradiation - Radiation (60-Gy in 30 fractions over 6 weeks) with daily oral temozolomide.
* Adjuvant chemotherapy - Daily oral temozolomide (5 days per 4-week cycle, starting 4 weeks after completion of chemoradiation, with at least 6 cycles intended).

MTP:

- Two 5-day fasts (allowing water, salt, tea, coffee, and a magnesium supplement) during chemoradiation followed by a 5-day fast during each adjuvant chemotherapy cycle, with a time-restricted modified ketogenic diet (one or two 1-hour eating windows per day, allowing oils, meats, vegetables, nuts, seeds, limited berries, and a multivitamin) between fasts.
