This week on the 20 Minute Fitness podcast we were lucky enough to have Robb Wolf on the show, who is a two times New York Times and WSJ Best Selling author and runs the popular podcast, The Healthy Rebellion Radio. By training, Robb is a bio-chemist and had mainly done research in cancer & autoimmunity. Following a personal health crisis, Robb has done extensive digging and has found low carb, keto ancestral diet to be a solution for better health. Listen to this week's episode to learn about metabolic flexibility, the factors that play a role in it, and to find out whether there is such thing as optimal nutrition!
