Nutrition & Metabolism
What actually moves the needle on metabolic health
Cutting through the noise around diet, supplements, and metabolic health. What the research actually says about protein intake, continuous glucose monitoring, intermittent fasting, and the GLP-1 revolution.
Why It Matters
Metabolic dysfunction — insulin resistance, fatty liver, and the conditions that flow from them — has become the defining health crisis of our time. More than 90% of American adults have some form of metabolic issue. But nutrition science is also infamously contradictory, with new fads appearing every year. The goal is to separate what actually works from what's marketing, and to find sustainable practices rather than crash interventions.
Questions I'm Exploring
"How much protein do older adults actually need?"
"Are GLP-1 drugs (Ozempic, Mounjaro) appropriate for people without diabetes?"
"Is intermittent fasting real or overblown?"
"Should healthy people wear continuous glucose monitors?"
Companies & Technology I'm Tracking
Levels Health
WatchingDevice
Continuous glucose monitoring for non-diabetics as a metabolic feedback tool.
Key point: Valuable as a 2-4 week learning experience; mixed evidence for long-term daily use
Zoe
CautiousPlatform
Personalized nutrition service based on blood sugar and gut microbiome testing.
Key point: The research foundation is solid; the personalization is less predictive than marketed
