Fasting is more than simply taking a break from food — it’s a powerful signal that activates some of your body’s natural repair and renewal processes.
In this episode of the Functional Nutrition Podcast, I will break down what happens hour by hour during a 30-hour fast and why this practice can have such a profound impact on metabolism, gut health, and longevity.
From Fat Burning to Cellular Repair
As your fasting window extends, your body begins shifting from using stored glucose for energy to burning fat and producing ketones.
I explain how lower insulin levels, improved fat metabolism, and increased ketone production support energy, brain function, and a healthier inflammatory response.
How Fasting Supports Your Gut and Longevity
A longer fast gives your body time to reset key systems, including your gut microbiome and intestinal lining. Learn how fasting may help remove weaker cells, support healthier gut function, increase growth hormone, and activate pathways associated with repair and healthy aging.
Listen to this episode to discover what’s really happening inside your body during a 30-hour fast and how you can better understand the science behind fasting for health and longevity.
