Dr. Spencer Nadolsky (aka The Doc Who Lifts) is a specialist in obesity medicine, and renowned weight loss coach. He's also one of my business partners and close friends.  I brought Dr. Spencer on to discuss evidence based approaches to eating and exercise, the benefits, as well as the drawbacks, and to help us dissect an interesting new study that came out around the idea of "nutritional periodization", which we've both been advocates of for some time. We also talk a bit about fasting, and give some real, practical ways that people can start losing weight.  A short but powerful episode. Hope you enjoy.
