Israetel used to have a column in Powerlifting USA as their nutrition guy. I don't remember it being great, but he was young, and I bet he worked cheap. This was in the later years of the mag.

Then about 10 years ago he tried entering the influencer space as a powerlifting influencer, this didn't workout, as powerlifters are cheap. A young chubby Israetel on a couch that looks like it should be in a porn -

He then got a tiny pop trying to be a BJJ strength coach, but that fizzled. Then he got his first major pop from aligning with the science based guys. That worked for a while, but then other exercise science guys started questioning him, etc...., so he's more careful with that a bit. Now his main schtick is reviews of people's programs and gossipy stuff under the guise of being scientific.
It's working too, he's got almost a 1,000,000 subs and does great on views. He's sorta the new Doucette, and I think that's why Doucette has been so aggressive covering him. Israetel has been cutting into the Youtube bucks.
