Summary

The duo’s recent pilgrimage to Texas ended with a trip to the state-of-the-art Texas Tech University body composition lab led by Dr. Grant Tinsley. Eric and Omar went through a battery of body composition assessments and had their RMR tested there, and Eric’s second epic duel with the Bod Pod went down. This duel resulted in only partial redemption for Eric, and we also learned just how “headstrong” Omar truly is. In this episode Grant joins Iron Culture to discuss the findings of the trip and all the nuances of body composition testing to help us understand the sometimes non-intuitive results the team got, and more broadly the pros, cons, strengths and weaknesses of the various body composition tests that are available.

00:00 The controversy that the Iron Culture won’t stand for

08:03 Welcoming back on the podcast, Dr Grant Tinsley

13:27 Understanding how body composition is estimated by multiple compartment methods

31:20 The applications of bioelectrical impedance for physique sport peaking

37:00 All about DEXA and how it fits into the six-compartment model

57:24 Explaining errors within body composition assessment

1:08:23 How measurements can be affected and the future of body composition testing

1:19:15 How metabolism is measured and metabolic adaptation

1:30:55 Thanking Dr Grant Tinsley and closing out (The BodPod)

0:03.1	We got to talk about this now man
0:05.8	It is something that's come to a head
0:09.6	It has and it's something
0:12.1	Folks we've had a lot of controversies
0:14.6	In our culture not due to our own fault
0:17.9	But due to naysayers, haters
0:20.1	and just general trolls online that we
0:22.4	will not stand for that villainy.
0:24.7	Um, and something came up, however, that sometimes people assume that hate only affects
0:30.6	the online sphere, but there was an event when myself and Eric met up in the UK at the historic the Sheffield competition, where we went
0:41.3	afterwards to Solet University. And Eric, let me describe him. Okay. Picture just something carved out
0:50.1	of marble, a statuesque figure. Allegedly he he thought he was around, what did you think you're
0:54.8	around at that time, Eric, your body fat percentage at Sheffield? Like, realistically, what Eric
0:59.2	knows about Eric, bodybuilding, your top shelf coach, what did you think you wore? Like a legitimate
1:05.2	body fat percentage? Bro, legitimate. Yeah. 12 or 13% probably. That is the amount that when I use the eyeball test,
1:12.9	which we know, Grant, okay, it's not accurate, but just bear with me here. We're all there.
1:17.0	There's some other PhDs. We had Milo Wolf there. We add PAC. Everyone's concurring. Eric's looking good.
1:23.0	So we go there feeling great because here we have access at this university to a bod pod,
1:29.9	which Eric's going to describe what that is.
1:32.0	And Eric volunteers himself to test his body fat percentage to show like, hey, this is the scientific process of like, we're going to do this, we're going to test it.
