In This Episode:
If you’ve ever wondered whether fasting actually does anything for inflammation, or just leaves you hungry and cranky, this episode lays out the science hour by hour.
I walk through exactly what your body is doing at every checkpoint of a fast, from the moment your last meal clears your system to the full immune system rejuvenation that happens days later.

The Fasting Timeline: What Happens Hour by Hour
Fasting isn’t just “not eating” — I break down the specific biological shifts that build as the hours pass: a full gut and liver detox cycle completes by hour 12, insulin drops and fat burning kicks in around hour 14, ketones and BDNF rise between 16 and 18 hours for sharper mental clarity, and autophagy accelerates from 18 to 24 hours as the body clears out damaged cells.
At hour 24, human growth hormone surges dramatically, and by 36 hours the gut microbiome shifts toward beneficial bacteria while intestinal stem cells increase.

How to Build Up to a Longer Fast Safely
A multi-day fast isn’t something to jump into cold. I share a practical, step-by-step progression: start with a 12-hour overnight fast, build to 14 hours, then work up to a daily 16-to-18-hour window most days of the week.
From there, add a weekly 24-hour fast for a growth hormone surge, and once that feels manageable, consider a monthly or quarterly 48-to-72-hour fast for a full immune system reset — or, for the deepest level of healing, a 3-to-5-day fast for peak autophagy and stem cell increase.
