Great to be here.

Absolutely.

My pleasure.

Awesome.

Thanks, man.

Yeah, I just try to track what the weirdos are doing on the weekends with their free time.

Yeah, the 4-Hour Body was 2010, which meant I started writing in 2008.

So I remember having a first-generation continuous glucose monitor.

This was back when it basically had to fall off the back of a truck because Dexcom was only selling to type 1 diabetics.

And the older continuous glucose monitors basically had these prongs, looked almost like something you'd use for a barbecue that you had to put under, into your abdomen sideways.

And then you had this, no smartphone, beeper-like device to track it.

So unpleasant.

i remember reading the book but i feel like it was like 10 15 years ago it was a long time 2010 is when it came out okay so it was so i was using it i was using the device quite a bit before that had to tape plastic over it to allow me to take showers i probably had that in for a good month or so it was enough time to make it worthwhile i mean more recently i've done lots of tests with much more pleasant wearables and so on but

A lot of that holds up, like, the durability of the stuff in that book.

Like, there are a few tweaks I would make, but by and large, everything has more scientific support now.

No kidding.

And it's not super surprising.

Like, sometimes people in the field get things wrong, but if you want to track, let's just say, what is going to be more validated by exercise science and randomized controlled trials five years from now, it's like, go talk to the coaches on the field.

Actually see what the athletes are doing.

The people who have huge incentives to win, the people who are playing that game, they're always going to be pushing the envelope.
