What is the reason for Alistair's weight loss?

On the podcast, Alistair said that he had lost a bunch of weight after meeting with a nutritionist and deciding to become a vegetarian.

“He’s like, ‘Yep, we’re gonna detox.’ I’m like a soldier,” Alistair explained said. “’Okay, let’s go.’ When I met him, I instantly knew this guy has knowledge, so we started working, and I started taking these supplements in a reasonably high dosage, which you can just do on an empty stomach. And after a couple of weeks, my diet, my appetite changed.”

Alistair had previously been known to eat steak at 8 a.m. to build muscle and regularly ingest horse meat, but he said that his diet changed pretty quickly.

"When I spoke to Julian [the nutritionist], I asked him what’s happening,” Alistair said. “I don’t want to eat my steak anymore, but I want to eat my steak because I want muscles."

"And he said, ‘You had parasites in your body. We gave you the supplements, you start detoxing your body,’ and these supplements are just simple seaweed," the former fighter continued.

"It’s not me who needs to eat meat, it’s the parasites that influence me, work through me to make me think I want to eat meat, but it’s not me. And once you get rid of them, you don’t care," Alistair added.

Alistair also announced his retirement.

During the interview, Alistair, who is now 43, also announced that he was giving up fighting during his appearance on the podcast.

“I actually just decided to stop fighting,” Alistair said casually. “This is not my thing anymore. It’s been 25 years, right? We’re going to do other cool stuff now.”

What Alistair meant was that he would spend more time promoting health in the way that he did throughout his time on the podcast.

Alistair is a former Strikeforce and DREAM champion who was released from the UFC in March of 2021. Over the course of his professional career, he had a record of 47-19 and proved himself to be a reliable fighter inside the ring.

Some fans were likely alarmed by the image of Alistair looking so skinny when for most of his career as a fighter he's intentionally built muscle. Thankfully, though, his new appearance had little to do with any health problems and was instead just an attempt to reset his body after a physically demanding career.
