Summary

***JOIN THE NEXT MASTER YOUR FASTING CHALLENGE THAT STARTS October 1st, 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 examines a critical 2025 systematic review and meta-analysis of 12 randomized controlled trials involving 966 type 2 diabetic participants, revealing a sobering truth about intermittent fasting: while it produces remarkable short-term benefits, these gains completely disappear after discontinuation. Dr. Scott and Tommy analyze how various fasting protocols (time-restricted eating, fast-mimicking diets, periodic fasting) significantly reduced A1C levels, fasting blood glucose, and body weight in under three months - but all parameters returned to pre-intervention levels within three months of stopping. This research powerfully illustrates why fasting must be approached as a permanent lifestyle change rather than a temporary diet solution. The hosts address the staggering diabetes epidemic: 38 million diagnosed Americans, 9 million undiagnosed, and 98 million with prediabetes - totaling 145 million Americans on the diabetes spectrum. Learn why the "rebound effect" occurs when fasting habits aren't sustained, and discover practical strategies for long-term adherence through personal anecdotes about adapting fasting to real-life situations like family dinners and social pressures. The episode introduces the concept of "momentary maintenance" - deliberate pauses in fat loss to build confidence in weight control rather than viewing plateaus as failures. This research validates that consistency trumps perfection, emphasizing that intermittent fasting works brilliantly when maintained but requires the same ongoing commitment as any other health practice to preserve its metabolic benefits. ⁠⁠⁠Take the NEW FASTING PERSONA QUIZ! - The Key to Unlocking Sustainable Weight Loss With Fasting!⁠⁠⁠⁠⁠⁠⁠⁠ Resources and Downloads: ⁠⁠⁠⁠⁠⁠⁠⁠SIGN UP FOR THE DROP OF THE ULTIMATE GUIDE TO BLOOD SUGAR CONTROL⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠GRAB THE OPTIMAL RANGES FOR LAB WORK HERE! - NEW RESOURCE! ⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠FREE RESOURCE - DOWNLOAD THE NEW BLUEPRINT TO FASTING FOR FAT LOSS!⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠SLEEP GUIDE DIRECT DOWNLOAD⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠DOWNLOAD THE FASTING TRANSFORMATION JOURNAL HERE!⁠⁠⁠⁠⁠⁠⁠⁠ Partner Links: Get your⁠⁠⁠⁠⁠⁠⁠⁠ FREE BOX OF LMNT⁠⁠⁠⁠⁠⁠⁠⁠ hydration support for the perfect electrolyte balance for your fasting lifestyle with your first purchase⁠⁠⁠⁠⁠⁠⁠⁠ here!⁠⁠⁠⁠⁠⁠⁠⁠ Get ⁠⁠⁠⁠⁠⁠⁠⁠25% off a Keto-Mojo⁠⁠⁠⁠⁠⁠⁠⁠ blood glucose and ketone monitor (discount shown at checkout)! ⁠⁠⁠⁠⁠⁠⁠⁠Click here!⁠⁠⁠⁠⁠⁠⁠⁠ Our Community: Let’s continue the conversation.
