Are ketone supplements the next big thing in sports performance, or just overpriced hype that tastes like jet fuel? In this episode of Your Diet Sucks, Zoë and Kylee break down the science behind exogenous ketones, including what they are, how they work, and whether they actually improve endurance, recovery, or brain function.

We explore the difference between ketone esters, salts, and precursors like Ketone IQ, plus the wild backstory—from epilepsy treatments to DARPA’s “Metabolic Dominance” program to the Tour de France. You'll learn what the research says about using ketones for weight loss, blood sugar control, and athletic performance, and why most runners probably don’t need them.
