How did your body respond to the last carb heavy dinner you had? Does eating a high calorie meal affect you worse than a lower calorie, higher carb meal? Herman Pontzer, an evolutionary biologist, did a research study on a hunter gatherer community called Hazda in Tanzania, to learn about energy expenditure. What he\u2019s discovered flips everything you thought you knew about calories and carbs upside down. He\u2019s joining Tom to expose why the data shows that carbs in a calorie controlled environment do not matter. Meaning, it is possible to theoretically go on a Twinkie diet (please don\u2019t) and still lose weight when calories are adhered to. Herman is using data to push back on how calories are burned and how they signal your brain to control your weight.\nOrder Herman Pontzer\u2019s book, Burn: New Research Blows the Lid Off How We Really Burn Calories, Lose Weight, and Stay Healthy : https://www.amazon.com/Burn-Research-Really-Calories-Healthy/dp/0525541527\xa0\nAlso check out the Hazda Fund (https://www.hadzafund.org/about) to learn more about the Hazda culture\xa0\n\nSHOW NOTES:\xa0\n0:00 | Introduction to Herman Pontzer \n1:40 | The Calorie Debate \n6:14 | How We Burn Energy \n12:09 | Obesity Starts In The Brain \n14:43 | Hypothalamus Function \n19:25 | Brain Response to Calories \n29:06 | Food Calorie Signaling \n32:36 | Optimal Lifestyle \n34:53 | Processed Food Brain Hack \n38:31 | Why Sugar Is A Problem \n42:22 | Hi Carb Diet Weight Loss \n45:24 | Fantasy Diet Study\xa0\n\nFollow Herman Pontzer: \nWebsite: https://sites.duke.edu/pontzerlab/people/ \nTwitter: https://twitter.com/hermanpontzer \nInstagram: https://www.instagram.com/hpontzer/ \nFacebook: https://www.facebook.com/herman.pontzer\n\nCheck out our sponsors:\xa0\nAthletic Greens: Go to athleticgreens.com/impact and receive a FREE 1 year supply of Vitamin D AND 5 free travel packs with your first purchase! \nButcherBox: Skip the lines for your Thanksgiving turkey.
