How should I break a 36-hour fast? | Masterjohn Q&A Files #158

Question: How should I break a 36-hour fast?

The two things that I would think about are your digestion, it's probably going to take a little bit of time to ramp itself up. I don't think you're going to do any harm by eating things that are difficult to digest, probably not great for your microbiome, but probably something that would just adapt to you. And so I would take that very subjectively. In your experience, what types of things do you have trouble digesting from when you stop a fast? But I think it's going to be fairly common to feel like some things just don't digest this well when you come off at 36 hour fast than you otherwise would. I think that's very subjective. My main concern from a health perspective would be feeding syndrome. So generally when you're fasting, you lose phosphorus because the phosphorus is associated with carbohydrate metabolism and your glycogen levels have been depleted.

Chris Masterjohn, PhD hosts Mastering Nutrition, a podcast that digs into the science of how our bodies work at a fundamental level. The focus here is on mitochondrial health-the energy powerhouses within our cells-and how optimizing them forms the cornerstone of lasting vitality. Chris brings his background as a nutrition scientist and his experience founding BioOptHealth to these conversations, which move beyond generic diet advice. Instead, the podcast explores how individual differences, informed by tools like whole genome sequencing and detailed biochemical data, can reveal personalized paths to better metabolic function. Listeners will hear deep dives into cutting-edge research, practical interpretations of complex studies, and discussions on how to apply these insights in a real-world context. This isn't about quick fixes or trending superfoods; it's about building a coherent, scientifically-grounded understanding of nutrition from the cellular level up. Each episode aims to provide the kind of nuanced, evidence-based perspective that can help you make sense of conflicting health information. Whether the topic is a specific nutrient, a metabolic pathway, or a broader principle of wellness, Chris works to translate dense science into actionable knowledge. Tune in for a thoughtful, detailed exploration of what it truly means to master your own nutritional landscape.
