How can the average person get and stay in shape without living at the gym?    That’s the question Dr. Bill Campbell, fat-loss expert and professor of exercise physiology, has dedicated his career to answering. He joins me in this episode to share the essential lessons he’s learned while running the University of South Florida’s Physique & Performance Lab. We cover a lot of ground, like fat-loss myths and facts, anti-aging training, and how to get and stay fit using a lifestyle you can maintain. Then, Dr. Campbell definitively answers a question I hear frequently: Is it really true your body can’t use more than 22g of protein at a time?    The best part? He’ll be back next week for part 2 of this fascinating conversation. You won’t want to miss any of it!   FULL show notes: jjvirgin.com/bodybyscience   Take my 7-Day Eat Protein First Challenge: http://jjvirgin.com/proteinfirst   Subscribe to my podcast: http://subscribetojj.com   Learn how foods cause leaky gut in The Virgin Diet: https://store.jjvirgin.com/products/the-virgin-diet-paperback   Read my book Sugar Impact Diet: https://store.jjvirgin.com/collections/books/products/sugar-impact-diet-paperback-book   Learn more about Dr. Bill Campbell: https://www.billcampbellphd.com Follow Dr. Campbell on Instagram: https://www.instagram.com/billcampbellphd   Get the Body by Science Research Review: https://www.billcampbellphd.com   DEXA scan: https://dexascan.com/   Tanita scale: https://amzn.to/3U4GtRQ   Reignite Wellness™ Clean Creatine Powder: https://store.jjvirgin.com/products/clean-creatine-powder   Reignite Wellness™ All-In-One Shakes: https://store.jjvirgin.com/collections/shakes   Learn more about Blue Zones: https://www.bluezones.com/   Study: Obesity Reviews: Obesity: The protein leverage hypothesis: https://pubmed.ncbi.nlm.nih.gov/15836464/   Reignite Wellness™ Amino Power Powder: https://store.jjvirgin.com/products/amino-power-powder Get Dr. Campbell’s Greatest Hits of Body by Science: https://www.billcampbellphd.com/greatest-hits-year-1 Learn more about your ad choices.
