·1 hr 16 min·5 clips

Drew Harrisberg, diagnosed with type 1 diabetes at 22, now says he's healthier than ever before.

Dr. Ron Ehrlich hosts Drew Harrisberg, an exercise physiologist, sports scientist, and diabetes educator living with type 1 diabetes. The episode opens with an acknowledgment of the Gadigal people and introduces Drew's expertise and personal health journey. Drew explains the 'rainbow diet' concept, emphasizing color diversity in plants to obtain various phytonutrients, and mentions the Essential Rainbow supplement from Amelie. The discussion shifts to protein requirements, where Drew argues that 0.8g/kg is insufficient for older adults or athletes, recommending 1.2-1.6g/kg instead. He addresses plant-based protein challenges, noting bioavailability and the need for diversity or supplementation. Essential amino acids and fatty acids are covered, with Drew suggesting algae oil for omega-3s and B12 supplementation for vegans. Drew clarifies he is plant-based at home but opportunistic with animal products to reduce waste. Dr. Ehrlich questions the evolutionary basis for meat consumption and vegan diets' historical viability, leading Drew to focus on current health outcomes. They touch on children's nutrition, with Drew cautioning against enforcing veganism without careful planning. The conversation moves to exercise, where Drew defines HIIT and its benefits for VO2 max and longevity, referencing Michael Mosley. They debate 'calories in, calories out,' with Drew reframing it as energy stored versus burnt and emphasizing diet over exercise for weight management. Drew shares his type 1 diabetes diagnosis story, including symptoms like rapid weight loss and thirst, and his dietary evolution from paleo to keto to plant-based, which improved his glucose management. He uses a continuous glucose monitor and aims for over 90% time in range. The episode concludes with Drew's tips on plant diversity and daily movement, highlighting environmental challenges to health.
