LYLE MCDONALD: INTERMITTENT MODIFIED FASTING: A NEW FRAMEWORK FOR FAT LOSS, PERFORMANCE & NUTRITIONAL PERIODIZATION | EP. 234
from Chasing Clarity: Health & Fitness Podcast · host Brandon DaCruz
When most people hear “intermittent fasting,” they immediately think about skipping breakfast, eating within an 8-hour window or going extended periods without food.But Intermittent Modified Fasting is something very different.On this episode of the Chasing Clarity Health & Fitness Podcast, I’m joined once again by Lyle McDonald to break down the framework behind his newest book, Intermittent Modified Fasting. This is the first interview Lyle has done since releasing the book. Rather than treating IMF as another fasting protocol, Lyle has brought together concepts from decades of his work on rapid fat loss, calorie cycling, training, body composition and sports nutrition to create a system for strategically distributing energy restriction across the week.And that creates a much more interesting question than simply asking whether fasting “works.”Can we manipulate where we place our calorie deficit to lose fat while better supporting training performance, recovery and lean mass retention?Throughout this conversation, Lyle and I each give our perspectives on how these concepts can be applied in both physique-focused clients and athletes.IN THIS EPISODE WE COVER:WHAT INTERMITTENT MODIFIED FASTING (IMF) IS & WHY LYLE DEVELOPED ITWHETHER INTERMITTENT FASTING HAS UNIQUE METABOLIC OR FAT-LOSS BENEFITSWHY INCREASED FAT OXIDATION DURING A FAST DOESN’T AUTOMATICALLY MEAN GREATER BODY FAT LOSS IMF AS A FORM OF CALORIE CYCLING & NUTRITIONAL PERIODIZATIONHOW TO SYNCHRONIZE CALORIE & CARBOHYDRATE INTAKE WITH TRAINING DEMANDSRFL DAYS VS MAINTENANCE DAYSBALANCING AGGRESSIVE FAT LOSS WITH TRAINING PERFORMANCE, RECOVERY & MUSCLE RETENTIONHOW IMF CAN BE MODIFIED FOR STRENGTH, ENDURANCE & PERFORMANCE ATHLETESHOW TO CREATE THE LARGEST PRODUCTIVE DEFICIT WITHOUT COMPROMISING THE ATHLETE’S PRIMARY PERFORMANCE GOALThe biggest theme throughout this episode is that the goal isn’t simply to create the largest calorie deficit possible.The goal is to intelligently distribute that deficit in a way that allows us to achieve the desired rate of fat loss while preserving the things we don’t want to sacrifice in the process.If you’re interested in fat loss, physique development, sports nutrition or understanding how to better periodize nutrition around training, this episode is for you.WHERE TO CONNECT WITH ME:Follow Brandon on IG:https://www.instagram.com/brandondacruz_/For Info on Brandon’s Coaching Services:https://form.jotform.com/bdacruzfitness/coachinginquiryEmail:[email protected]’S NEWEST BOOKS: https://store.bodyrecomposition.comcode: larrywon20% off until Oct 7
