Summary

In this research-focused episode, Dr. Scott Watier and Tommy Welling break down a groundbreaking four-week study from the Journal of Clinical Nutrition comparing alternate day fasting (true zero-calorie fasting days alternating with unrestricted eating days) against standard 16:8 time-restricted eating, revealing that ADF produced £1.4 more total fat loss and significantly greater visceral fat reduction than daily intermittent fasting—the stubborn metabolic fat that drives disease. The hosts emphasize the surprising finding that the ADF group was the only one showing increased activity energy expenditure and improved quality of life scores despite being in an aggressive caloric deficit, demonstrating that people actually felt better and moved more naturally rather than experiencing the typical diet misery. They provide crucial context on metabolic adaptation, explaining why the slight decrease in resting metabolic rate and T3 thyroid hormone with ADF only becomes problematic if prolonged, which is why they recommend strategic 2-4 week ADF cycles followed by foundational 16:8 or 18:6 fasting to protect metabolism while still achieving powerful visceral fat loss. This episode delivers the practical framework for using ADF as an intermittent power tool within a sustainable fast-cycling lifestyle—not as a white-knuckle permanent strategy like Angus Barbieri's 382-day fast or repeated brutal 72-hour fasts—while protecting muscle mass through resistance training and adequate protein to create lasting body composition changes without sacrificing energy, sanity, or long-term metabolic health. ⁠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.

Hello, I'm Dr. Scott Wadier.

0:03.0

And I'm Tommy Welling, and you're listening to the Fasting for Life podcast.

0:07.0

This podcast is about using fasting as a tool to regain your health, achieve ultimate wellness, and live the life you truly deserve.

0:15.0

Each episode is a short conversation on a single topic with immediate actionable steps.

0:20.0

We cover everything

0:21.2

from fat loss and health and wellness to the science of lifestyle design. We started fasting

0:25.9

for life because of how fasting has transformed our lives and we hope to share the tools

0:29.9

that we have learned along the way.

0:31.6

Hey everyone, welcome to the Fasting for Life podcast.

0:42.2

My name is Dr. Scott Wadier, and I'm here, as always, I'm a good friend and colleague, Tommy

0:45.1

Welling.

0:45.9

Good afternoon to you, sir.

0:47.6

Hey, Scott, how are you?

0:48.8

Doing fantastic, my friend, excited for today's conversation.

0:52.7

We're going to be getting into an article

0:55.2

that just recently came out in the Journal of Clinical Nutrition.

0:59.6

It is alternate day fasting elicits larger changes in fat mass

1:04.2

than time restricted eating, aka fasting,

1:06.9

in adults without obesity.

1:08.8

So we're talking about BMI of 23 to 30,

1:11.6

so in that normal to overweight category,

1:14.6

we're gonna expand this out to encompass all fasting lifestyles
