Intermittent Fasting and Athletic Performance

During the past 10 years or so there’s been a lot of chatter about the health benefits of intermittent fasting — that is, going without food for a short window of time on a regular basis. Some of the touted benefits of intermittent fasting include shredding body fat while maintaining muscle, improving blood sugar levels and insulin sensitivity, increasing longevity, and improving focus. But how many of those purported benefits are real and how many of them are just hype? 
Well, my guest today is a nutrition scientist who has spent the past several years researching and experimenting with intermittent fasting to find out the answers to those questions. His name is John Berardi and he’s the co-owner of Precision Nutrition, an online nutrition coaching company. John has written a free ebook that highlights all the latest research on intermittent fasting as well as his personal experiments with several different IF protocols. Today on the show John cuts through the hype of intermittent fasting and gives us a nuanced look at the benefits and downsides of this diet method. If you’ve been thinking about trying intermittent fasting, you don’t want to miss this show. John breaks down exactly who should use IF and who shouldn’t, and what kinds of results to expect when you fast.
