Cyrus has an undergraduate degree in mechanical engineering and worked for NASA before returning to school to earn a PhD in nutritional biochemistry. Cyrus shares his personal journey that led him from battling multiple autoimmune disorders—including a type 1 diabetes diagnosis— to exploring the science of nutrition, ultimately achieving a remarkable tenfold increase in insulin sensitivity through dietary changes.

In Cyrus’s first year of managing his diabetes, he found that his insulin needs kept going up, even though he was following the low carb approach his doctors had recommended. He was introduced to the concept of a whole food plant-based diet, and since he was frustrated by his experiences managing his blood glucose, he was willing to try anything. He was shocked to discover that within one week, he went from requiring 42 units of insulin per day to only 24 units per day. He knew he wanted to understand what was happening in his own body, and was inspired to go back to school to learn more.

Cyrus explains the science of how whole food, low-fat plant-based diets are conducive to both improved blood sugar levels and improved insulin sensitivity, despite common misconceptions to the contrary. Cyrus delves into the scientific research, which underscores the negative impact of high-fat diets on insulin sensitivity. Diving deeper into the science, Cyrus and Gin discuss Cyrus’s experiments on calorie restriction and intermittent fasting with laboratory animals, showcasing the significant reversal of insulin resistance.

Cyrus wraps up the episode with advice for listeners who may be grappling with similar health issues or seeking healthier lifestyles. He underscores the essentials: belief in the process, openness to new information, and embracing the robust scientific evidence supporting plant-based diets combined with intermittent fasting. Encouraging personal research and understanding, Cyrus leaves listeners with a powerful parting message – to approach one’s health journey with curiosity, to avoid being swayed by prevalent dietary myths, and to seek empowerment through knowledge, concluding with an invitation to explore the wealth of resources available, such as his Mastering Diabetes program, for anyone ready to take control of their health and well-being. You can connect with Cyrus and his team through
