Carbohydrates: The Key to Midlife Health & Performance with Kristen Arnold, MS, RDN, CSSD (Episode 256)

“Carbs are evil.” As we usher in 2026, and as endurance athletes around the globe are stuffing down as many carbohydrates per hour as humanly possible to supercharge their performance, this week’s guest, sports dietitian Kristen Arnold, still manages misconceptions, especially from her midlife clients, that carbohydrates are something to be cut from the diet. Nothing could be further from the truth. This week we kick off the new year with a show all about the life and performance-boosting benefits of carbs. We cover carbohydrate timing, processed carbs versus unprocessed carbs, carbohydrate’s impact on blood sugar, brain function, mood, inflammation, general health, and much, much more.
