Summary

***JOIN THE NEXT MASTER YOUR FASTING CHALLENGE THAT STARTS August 13th, 2025!*** We’ll GUIDE you on how to FAST to LOSE FAT for good, and use ‘fast cycling’ to achieve uncommon results! REGISTER HERE! Click the link for DATES, DETAILS, and FAQs! This episode reveals how aligning your intermittent fasting schedule with your circadian rhythm can dramatically improve weight loss and metabolic health. Dr. Scott and Tommy break down the science showing that eating the same meal at 8 AM versus 8 PM results in 30% less glucose processing effectiveness at night, making evening fasting windows less optimal. Discover research proving that women eating 70% of calories before noon lost significantly more weight than late eaters, and how just one hour of "social jet lag" (varying bedtime) increases diabetes risk by 40%. Learn the three main circadian disruptors sabotaging your fasting success: excessive blue light exposure at night, irregular sleep schedules, and late-night eating. The hosts explain why your worst cravings happen after dinner (it's biology, not willpower), how light exposure while sleeping increases BMI and waist circumference, and why shift workers have higher rates of metabolic dysfunction. Get actionable strategies for optimizing your fasting windows, including morning sunlight exposure protocols, blue light protection methods, and why turning off kitchen lights during evening fasts can eliminate food cravings. This episode provides the missing piece for fasters struggling with plateaus, hunger, or inconsistent results - showing how to work with your body's natural 24-hour clock rather than against it. Essential for anyone wanting to maximize their intermittent fasting results by understanding when your body is primed for fat burning versus fat storage throughout the day.
