Ketones: Biohacking or B.S? The Science of Ketone Supplements

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: what they are, how they work, and whether they actually improve endurance, recovery, or brain function.

We dig into the differences between ketone esters, ketone salts, and precursors like Ketone IQ, and trace their wild backstory, from epilepsy treatments to DARPA’s “Metabolic Dominance” program to their controversial rise in the Tour de France. Along the way, we unpack what the research really says about ketones for weight loss, blood sugar control, and athletic performance, and why most runners, athletes, and fitness enthusiasts probably don’t need them.
