Self Experiments In the Biochemically Unoptimized State

Self Experiments In the Biochemically Unoptimized State

Finally, the long-awaited results of my self-experiments conducted from September through January are released!

The primary abnormalities in my metabolism during this pre-biotin period were 1) 15 minutes of paradoxical rise in ketones after eating rice, 2) paradoxical rise in lactate during fasting that is suppressed by my meals, and 3) a massively outsized lactate response to alcohol. The first two were provoked by an 18-hour fast and the last by undereating prior to the alcohol.

These support a deficiency in the biotin-dependent, manganese-dependent, oxalate-poisoned enzyme pyruvate carboxylase.

This is long, and if your time is limited, you may want to skip to "The Bottom Line" in this link: https://chrismasterjohnphd.substack.com/p/self-experiments-in-the-biochemically

However, there are some major reasons to commit some time to reading the whole report: It serves as a crash course on the most relevant biochemistry of glucose, ketones, lactate, and ethanol across contexts that include general health, diabetes, infancy, and pregnancy. It includes a literature review of all of the relevant "normal" data.

For example, what usually happens to lactate during fasting?

What is the normal response of ketones to a glucose tolerance test at the 15-minute mark?

How high should you expect your lactate to go up when you drink vodka, bourbon, or beer?

I have laid out a model of self-experimentation that you can borrow from for your own experiments.

 There are many thought-provoking nuggets in here.

For example: Is it possible that two pounds of extra body fat prevents peripheral neuropathy in me and perhaps others? I make the case that it may.

Has your fasting glucose gone up on low-carb? See why mine went down after doing repeated glucose tolerance tests on myself (which I don't recommend at home!) 

And, learn why I can fast my way to a glucose of 70 or eat my way to a glucose of 70 and I would choose eating my way there every time.

Chris Masterjohn, PhD, is the Founder and Scientific Director of the mitochondria test Mitome.


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.
