Summary

This is a monster episode. Newly added co-host Eric Trexler details his impressive credentials, groundbreaking new line of research and perhaps most importantly, the best way to effectively execute a single leg take-down on an unsuspecting person.

His new appointment at Duke University will be looking in part at the topic of today, exercise energy compensation. It turns out that calories in, calories out is a little more complicated than most would assume. Made famous by Dr. Herman Pontzer and his book Burn, Dr. Trexler explores what exactly this phrase means, the utility of doubly labelled water and the future of research in this field.

0:00.0	Eric.
0:02.5	Omar.
0:03.9	It just feels so right, man, to have you on this podcast.
0:07.9	Is it the name thing?
0:09.0	Is that why?
0:09.8	I didn't want to say it.
0:11.4	And maybe Eric Trexler, welcome to officially your first hosting duty.
0:18.0	As a co-host, co-owner, you didn't know that. We have nothing, we have no equity.
0:22.9	There's nothing of, in fact, we're in massive debt. So really, you're taking on debt on behalf of
0:27.3	Iron Culture. Thank you. But it's now a holy trifecta at the top of the pyramid. Welcome officially
0:33.5	to Iron Culture. Well, I appreciate that. It is an honor to be here.
0:39.1	You know, my day job, I'm doing research at a, you know, institution no one's ever heard of.
0:44.0	So it's nice to be affiliated with an organization that actually commands some respect, you know.
0:48.5	So being part of Iron Culture is huge.
0:50.5	Yeah, we're really, we're popping off in the 18 to 24 crowd thanks to Eric's TikTok dances.
0:57.5	You know, anything older than that, we've definitely aged out of, but we're just trying to target, you know, the youth of tomorrow and let them understand what doubly labeled water is all about, which is what we'll be discussing today.
1:09.2	But I do have a few questions, man, because I, for one, and I'm echoing shout out to our hunky other co-host,
1:15.1	Eric Helms, who's currently competing right now. I have to give him a massive shout-out
1:18.3	on his win at his first competition. My man is looking yucky. But I'll speak on behalf of
1:23.4	both of us that we're thrilled to have you on board because you're one of the most important
1:28.1	voices. And I would say underrated because much like your fellow mass research reviewer, Mike Zordos,
1:35.0	you do a way better job being present on social media. I'll give you that, Treks. Zordos, I think,
