In this episode of "Nerding Out with Viktor," host Viktor Petersson sits down with Marcelo Garcia, a telecom infrastructure veteran turned extreme biohacker, to explore what biohacking looks like when approached through systems thinking and data.
Marcelo recently completed a 50-day water-only fast while hiking nearly 1,000 kilometers, tracking everything from DEXA scans and VO2 max to HRV and metabolic panels. The conversation moves from the mechanics of prolonged fasting and fat oxidation to muscle preservation under sustained load, immune adaptation, and the role of movement as a metabolic signal.
Viktor and Marcelo also discuss biological age modeling and how AI can synthesize large sets of biomarkers into practical health span projections. For builders and technically inclined listeners, this episode reframes resilience as something measurable, testable, and intentionally designed.
