and we are back for another edition of the wellness upgrade a solo episode today gonna go over something that i just did last week but hey no guest just me and my health and wellness journey today y'all hopefully can get something out of what i just did last week and some of the science behind it so We're going to dive in today to something that's really been practiced for thousands of years, but now is being popularized again through modern biohacking and performance science.
You've probably heard a lot of folks talking about the three-day fast now if you listen to any other health and wellness podcasts.
So if you've ever wondered, hey, what's a three day fast like or what happens when you don't eat for three whole days? What happens to your body? Is it safe or beneficial? Then this episode is for you.
I'm going to dive into the science behind it a little bit, but also give you my firsthand experience from just last week.
If you haven't heard of him, I guess he could be considered the father of biohacking.
He's kind of coined that term, biohacking, and he's written a couple of books about fasting, and he talks about that on his podcast, both intermittent fasting and a full 72-hour fast.
So breakfast, snacks, lunch, snacks, dinner, maybe even late night snacks after that.
But when you fast, especially beyond 24 hours, your body starts to shift gears.
You move from burning sugar, from that sugar burning mode, to more of a fat burning mode.
You're training your body to become more flexible, more efficient, and less dependent on constant fuel.
So why three days? Why a full 72 hours? Because that's really where things get interesting.
And that's where a lot of the research is really starting to back up some of what people have thought before but now we have some research to back that up you know short fasts like intermittent fasting is great but a three-day fast pushes your body into deeper biological processes like ketosis so by a little over 24 hours your glycogen stores are completely depleted and your body starts producing ketones a very clean burning fuel for your brain.
