#skipdinner #whathappenswhenyoufast #fastingexperiment #scienceexplained #brainclarity Many people believe that any calorie instantly destroys a fast. But Science Explained reveals a more accurate truth: fasting is controlled by insulin, not by calorie fear. In this video, Science Explained breaks down the biology behind ketones, fat mobilization, and the hormonal switch that determines whether your body continues burning fat. You’ll learn why certain foods like MCT oil, black coffee, or small amounts of fat may not significantly raise insulin — while hidden sugars can immediately pause fat burning. Rather than obsessing over zero-calorie myths, Science Explained helps you understand what truly flips the metabolic switch. This episode clarifies the difference between ketosis, autophagy, and simple calorie restriction so you can fast intelligently, not obsessively. If fasting has ever felt confusing or stressful, Science Explained gives you the hormonal logic behind every choice. Because once you understand insulin, Science Explained shows you that fasting becomes flexible, sustainable, and biologically aligned. 00:00 - Introduction 01:44 - What really “breaks” fasting? 06:38 - MCT Oil “The forced ketone switch” 10:47 - Black coffee & unsweetened tea 15:31 - Soluble fiber (Psyllium, basil seeds) 19:59 - Heavy Cream 24:20 - Bone Broth & Collagen 28:49 - Things that seem safe but aren't 33:21 - Don't Miss Out
