We are joined by nephrologist and obesity researcher Dr Jason Fung. Dr Fung is a researcher and clinician who is achieving superb results using fasting in the treatment of both obesity and diabetes. Dr Fung’s work brings together critical insights on insulin resistance, the nature of long term obesity, the weight set-point and how to alter it, and the incredible value of fasting as a treatment for obesity and diabetes. Dr Fung is the author of the The Obesity Code, and co-author of The Complete Guide to Fasting - two books that are essential reading for modern human beings trying to find their way back to health after significant weight gain.We discuss in some detail insulin resistance and the failed “energy balance” or “caloric balance” approach to weight management as well as the issue of “weight set point” and how we can influence and reset it. We also discuss the nature of fasting and how the reality of fasting is the opposite of everything we’ve been told...when we fast our metabolism actually speeds up. This discussion is centred on the dangers of chronically high blood insulin levels being suffered by a large percentage of the population in our contemporary society, whether they are fat or thin...and it dovetails significantly with the modern habit of snacking - a habit which has been largely driven by marketing since the latter 20th century, and which seems to have been one of the critical environmental changes contributing to the obesity epidemic.
