Do Athletes Really Need More Carbs? | Dr. Andrew Koutnik & Mike Haney

Dr. Andrew Koutnik, PhD — Visiting Research Scientist, Florida Institute for Human and Machine Cognition; studies nutrition, metabolism, Type 1 diabetes, and performance

Why muscle glycogen—your store of carbs—may not explain “the wall”—and how blood glucose, insulin, and metabolic flexibility can reshape how you fuel training.

Fructose, sucralose, allulose, and avoiding insulin resistance from sweeteners

Dr. Richard Johnson, MD; Dr. Dominic D'Agostino, PhD — University of Colorado School of Medicine (Johnson); University of South Florida (D'Agostino)

Fructose suppresses satiety, sucralose disrupts the microbiome, and allulose does neither. A breakdown of every major sweetener and which ones drive insulin resistance.

Astronaut Scott Kelly on CGMs, the NASA twins study, and metabolic health in space

Scott Kelly — Retired NASA astronaut; held US record for continuous days in space (340 days)

A CGM showed a retired astronaut his "healthy" cereal was one of his worst meals. What 30 days of real-time glucose data teaches — and how space physiology mirrors metabolic aging.

The benefits of biosensing for preventive medicine

Michael Dubrovsky — SiPhox Health; Co-founder & CEO

Annual blood tests are a single snapshot; biosensors give continuous film. How real-time data shifts healthcare from diagnose-and-treat to prevent-and-optimize.

Understanding blood sugar levels, insulin resistance, and impact on chronic diseases

Dr. Robert Lustig, MD; Dr. Dominic D'Agostino, PhD — UCSF (Lustig); University of South Florida (D'Agostino)

Insulin is the energy-storage hormone — when cells stop responding, everything breaks. How to test for resistance early, why rising insulin precedes rising glucose by years.

Insulin resistance and how it affects each of us differently

Dr. Benjamin Bikman, PhD — Brigham Young University; Professor of Cell Biology & Physiology; author of Why We Get Sick

Insulin resistance and the hidden effects of sugar on kids

Dr. Robert Lustig, MD — UCSF; Professor Emeritus of Pediatrics & endocrinologist; author of Metabolical

Sugar gives children fatty liver disease and type 2 diabetes by damaging their mitochondria. Why fructose is the main driver, and what dietary changes reverse the damage.
