Not the \"due for a snack\" kind. Properly, deliberately hungry, on purpose. If you can't remember, you're not alone. Now imagine using that discomfort as a lever instead of avoiding it.\nEvery reflexive snack, every meeting that runs straight into the next, every bite you take before your body even asks for it keeps you running on one setting. You never give your body the signal to switch fuel sources, sharpen your focus, or clean house at a cellular level. The fog, the afternoon slump, the stubborn weight that won't shift: that's the bill for never stopping.\nDr Tom Buckley has spent more than 22 years reading the bloodwork of Performance Intelligence's executive clients, translating what's happening inside hundreds of high performers into how they eat, train, and lead. He's back on the podcast to explain what fasting actually does inside your body, why the meal you were told never to skip has a cereal company to thank for that reputation, and how two nights a week without dinner might be the highest-leverage habit in your week.\nYou could keep running on constant fuel and wonder why your energy never settles. Or you could learn to use hunger as a lever instead of an enemy.\n03:35 The fat that's easiest to shift, and where it sits \n05:41 Ghrelin, leptin and the people who never feel full \n09:03 Three fuels, one easy habit: why carbohydrate wins by default \n10:27 Metabolic flexibility: the skill Western living has trained out of us \n16:08 The story that's driven Dr Tom for 35 years \n21:47 What fasting switches off first \n22:47 Ketones: the fuel that skips the insulin queue \n25:13 Fasting and the new GLP-1 drugs are chasing the same biology \n27:33 The shortcut risk: trading discipline for a jab \n28:17 What decades of fasting research actually agree on \n31:16 The benefits nobody puts on the label \n33:21 Andrew's own Tuesday and Thursday fast, and why it finally clicked \n36:01 The worst thing we do as humans, and the...","thumbnail_url":"https://img.transistorcdn.com/crvu0qkU_nPKdfaX6_m4Qg8iubjexgpghzQo9EZjyAU/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS83N2Fh/MWFmM2U1OTAyMDRj/ZDg3MTVjZTdiODM1/ZTVkYS5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
