Wim Hof has been working with scientists for decades, and there are entire chapters in textbooks about how he has helped develop our understanding of physiology [0]. Read the comments there! See https://www.wimhofmethod.com/scienc…
There is also evidence that Wim Hof's abilities are not related to his lifestyle, as he has a twin brother with similar responses, despite that his brother leads a sedentary lifestyle without any of the practices to cold exposure of his brother. https://en.wikipedia.org/wiki/Wim_Hof#Resistance_to_cold
I think you're misinterpreting the point of that study. "A lifestyle with frequent exposures to extreme cold does not seem to affect BAT activity and CIT (cold-induced thermogenesis)" is not the same thing as "Wim Hof's abilities are not related to his lifestyle."
Wim teaches people to do what he does. He has trained people to do some of the things he does, like their blood killing E. Coli (!), or bringing 70+ year olds up mountains in their boxers (!).
I know from personal experience that those methods increase resistance to cold. But you don't need to rely on my testimony, there's video of him teaching people this stuff. It's not a trick.
