Physiologist Drew Harrisberg On Everything Blood Glucose, Understanding Diabetes & Plant-Based Nutrition Fundamentals

A full-blown epidemic in the developed world, diabetes currently afflicts an astonishing 37 million people in the U.S. alone, and 1 in 5 Americans don’t even know they have it. An astonishing 96 million US adults (over one-third) have pre-diabetes, with the rate of Type 2 diagnoses among adults more than doubling in the last 20 years. To better understand this epidemic of metabolic dysfunction, I sat down with exercise physiologist, sports scientist, and Type 1 diabetic Drew Harrisberg. Diagnosed at 22, Drew shares his story, along with the diet and lifestyle changes he relies upon to thrive with his condition—changes he details and recommends not just for Type 1 diabetics but for anyone and everyone concerned about metabolic health and how to improve it. We go deep into the physiology of diabetes, the differences between Type 1, Type 2, and pre-diabetes, and what can be prevented or reversed versus managed through lifestyle, movement, mindset, and nutrition. We also discuss how diet and lifestyle impact blood glucose management generally, along with Drew’s take on the usefulness (or lack thereof) of continuous glucose monitors for non-diabetics. But perhaps what is most fascinating about this conversation is Drew’s experience searching for the optimal diet to manage his own condition, a journey that took him from Paleo, to Keto, to you guessed it, finally settling on a whole food plant-based approach to his nutrition—and all the why’s and how’s behind this decision. This episode isn’t just a must-listen for those that suffer from diabetes—because improved metabolic health is relevant to all. Enjoy!
