Bariatric surgeon Dr. Eric Smith joins the BariNation Foundation Podcast to continue the six-part series on the Levers of Control. Today's episode is about the second lever: Whole Food Nutrition. Dr. Eric Smith speaks with April Williams and Melanie Lindell to reveal why whole foods quiet food noise, how ultra-processed foods were engineered for overconsumption, and what it takes to build a sustainable, whole-food nutrition-based life after bariatric surgery and while pursuing a medically based weight loss program.
