When Simon suddenly couldn’t say the word “kilometre”, life flipped. Weeks later, a 4 cm frontal lobe tumour, urgent surgery with 94% resection, and ten days on the diagnosis: glioblastoma. In this episode, Simon and Kate share the shock, the sprint through ED to theatre, and the pivotal introduction to Dr Matthew Phillips’ metabolic therapy trial. We dig into the protocol-keto, intermittent fasting, five-day fasts aligned with chemo/radiation, and one-meal-a-day plus why Simon kept running 30-40 km a week through treatment. They talk candidly about energy, weight loss, a single seizure, extraordinary clinical support, and MRIs showing no recurrence post-treatment (Dec 2024 and again eight months later). You’ll hear the role of family, why they agreed to “learn together” and stop solo Googling, how to ask about trials, and what “focus on the here and now” looks like when the stakes are highest. A grounded, hopeful conversation about agency, discipline, and a life rebuilt.
