This guy says a lot of interesting things, and I like the sound of his voice. But, googling for stuff that really quantifies these effects isn’t turning up much. Like if 130 kcal of almond get absorbed in one part of the digestive tract, and 30kcal get absorbed farther down, it still sounds like 160kcal of almond is going into the body, and has to come out somewhere else, or it’s going to stay in there.
I've listened to about half of each and I think I believe the spotify / Lustig argument more.
For example, around 25:00 Lustig claims...
"[fructose in] fruit is okay because of the fiber and the fiber is what mitigates the absorption
[...]
you're feeding your microbiome. that frucose isn't for you."
And arouvd 10:50 Layne counters that
"I could find no evidence that fiber inhibits the absorption of fructose"
But searching for "fiber slows glucose absorption" on google scholar gives me a few frequently cited results [1], making me doubt Layne's research.
Also in terms of background, Lustig is a professor guest starring on a podcast sponsored by various companies (including one that sells supplements [2] [3]) versus Layne who runs a company that sells workout guides / supplements [4]. Not to say there's any obvious conflict of interest here, but I think the professor actively involved in research has more credibility.

> [the 30kcal] has to come out somewhere else, or it’s going to stay in there.
That's a good point. I'd love to know what the practical difference between my gut bacteria consuming energy vs rest-of-me consuming energy is too.
But yeah Lustig saying sugar was as addictive as heroin also raised a red flag for me. Maybe true in a technical sense but definitely shows he's trying to push a point (anti-corpo maybe?).
