What Others Are Saying
After years of following the rules, Dr Ian Lake began asking a different question: not just how to manage glucose, but how to optimise insulin. This book shares the journey, the science, and the mindset shift that followed.
“Dr. Lake writes not only as a physician but also as someone who has lived with the daily reality of Type 1 diabetes for decades. That dual perspective gives this book a rare authenticity.
His willingness to question assumptions — while remaining grounded in science — carries forward the spirit of pioneers such as Richard K. Bernstein and Keith Runyan.
What Dr Lake offers in these pages is not a rejection of established care but an expansion of it, encouraging deeper metabolic thinking while remaining practical and grounded in lived experience.”
“Dr. Lake is a cyclist and experienced clinician who takes us through his meticulous travel journal in Shifting Gears. With disarming wit and humor, he teaches you exactly how to optimise insulin therapy. Dr Lake demonstrates with brutal honesty, innovation and self-awareness how his 5 foundations process allows for the lowest and safest insulin doses. This book is a must read for anyone interested in understanding insulin, because Dr Lake's experiments bring us a wealth of knowledge and scientific data that inform us of a better way of delivering healthcare.”
“Ian Lake brings rare clarity and courage to the management of Type 1 diabetes. Weaving his cycling journey across Europe with the equally demanding terrain of blood glucose management, he combines lived experience with medical precision to transform daily guesswork into thoughtful, strategic care — showing what is truly possible.”
