I did a 4 DAY FAST and this is (the science of) what happened
In this video, I take you on a journey through the surprising world of extended fasting. Join me as I undergo a DEXA scan, embark on a 96-hour fast, and follow up with another DEXA scan to uncover the real effects of fasting on body composition.
What You’ll Learn:
DEXA Scan Basics: Understand what a DEXA scan measures and why it’s crucial for assessing body composition. Learn about the importance of tracking bone density, muscle mass, and fat distribution.
Fasting Insights: Explore how a four-day fast impacts muscle mass, visceral fat, and overall health metrics. See real data from my scans and learn about the potential benefits and downsides of extended fasting.
Ketones and Energy: Discover how fasting influences ketone levels and what this means for your energy and mental clarity. Understand the science behind ketosis and how your body uses fat as fuel during fasting.
Results Analysis: Dive deep into my personal DEXA scan results and learn what’s really happening inside your body during an extended fast. Get a detailed breakdown of changes in muscle mass, fat loss, and visceral fat reduction.
Throughout the video, I share my honest reflections on the experience, including unexpected benefits like increased mental sharpness and energy levels, as well as challenges such as muscle mass loss. This experiment sheds light on the complex relationship between fasting, health, and longevity.
Whether you’re curious about fasting for weight loss, improving health, or boosting mental acuity, this video provides a grounded, science-based look at what fasting can (and can’t) do for you.
