Diet Doctor Podcast #57 — Dr. Ian Lake

215 views Add as favorite
As a physician, Dr. Ian Lake broke free of dietary guidelines to treat his own type 1 diabetes and prove he could do better than standard care with a low-carb approach. Now he wants to spread that message to his patients and to all other physicians.

His key point is about the safety of low carb and fasting. Lake believes that we don’t need carbs for energy and that fasting is not the same as starvation. To prove it, he organized and completed the Zero Five 100 project. Zero calories. Five days. 100 miles.

Eight people started and safely completed this remarkable, well-planned journey. Through the process, Dr. Lake collected valuable data to help us understand the physiology of fasting and low carb and how it applies not only to those with type 1 diabetes but to all of us.

Will it be enough to change the paradigm of blood sugar management? That remains to be seen. But it’s an amazing start!

Thanks for reading,
