Part of the research of this book was just intellectual curiosity, but the other part was really necessity. I was diagnosed with a chronic disease in 2019. And I was very, very overweight. I was 210 pounds. So I lost about 50 to 60 pounds with a lot of research and end of one experimentation, et cetera. So fasting and intermittent fasting was a big one for me.

And in the early days, I was candidly pretty fundamentalist about it because I needed to be because... my fasting blood sugar was 125 milligrams per deciliter. So I was on the very, very top of the pre-diabetic range at the very bottom of the diabetic range. And I was having crazy spikes, you know, up to, you know, 250 milligrams, 300 milligrams per deciliter postprandially.

And so this is why now I wear this little disc on my triceps called a continuous glucose monitor. So fasting was one of the key protocols that I developed for me really early on. And it makes total sense because if you ask yourself the basic question, and this could be applied to all of these adversity memetics, how did I evolve, right? Well, I evolved having to endure periods of calorie scarcity.

My body was engineered to become a little fat in the late summer or the early fall. Why? Because it knew... that the paucity of winter was just around the corner. But of course, in most of the modern West now, winter never really comes from a food perspective. There's always a surfeit of shelf-stable, nutrient-deficient calories that we can call up in the palm of our hand.

By the end of this podcast, we could have a whole array of foods here, right, in and out of season. So I really had to examine this and say, listen, I need to balance my consumption of food with some degree of restriction. Because part of nature's plan is to balance abundance with some degree of scarcity. But now in an era of very little scarcity, we have to self-impose this protocol.

So this is what fasting was for me. For me, I adopted a very simple 16-8 protocol because I found that there was the most data around that. And that's simply just consolidating my consumption of food in an eight-hour window. For me, that was more or less between 10.30 and 6.30.

I've subsequently played with that window a little bit, but I saw very, very significant results pretty quickly from that protocol. Time-restricted eating doesn't mean you're necessarily calorie-restricting because you could eat 10 pints of Chubby Hubby in an eight-hour window, right?
