Summary

This episode breaks down groundbreaking research on hyper-caloric 16:8 time-restricted eating during 8 weeks of resistance training, proving you can build muscle and get stronger while maintaining an intermittent fasting lifestyle. Dr. Scott and Tommy analyze a study comparing fasted vs fed workout groups, revealing that the time-restricted eating group gained 50% more muscle mass (2.67kg vs 1.82kg) while gaining significantly less fat (0.26kg vs 1.67kg) even in a caloric surplus. Discover why fasted training leads to superior body composition changes - more muscle growth with minimal fat gain - making it ideal for physique-focused goals and maintenance phases. Learn the trade-offs: while the fed group showed slightly better strength gains (particularly in squat performance), the fasted group achieved the same total weight lifted with fewer reps, suggesting greater training efficiency. The hosts explain why this matters for long-term fasting lifestyle success, especially for those reaching maintenance goals who want to continue improving body composition without regaining weight. Get practical strategies for timing workouts with eating windows, understanding the adaptation period for fasted training, and choosing between performance-focused vs body composition-focused approaches. This episode provides evidence-based guidance for combining resistance training with intermittent fasting, showing that you don't have to sacrifice muscle building for fat loss - you can optimize both simultaneously with proper timing and nutrition strategies. ⁠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.
