Jon Jones says he's radically changed his diet for his upcoming fight with Dominick Reyes -- telling TMZ Sports, "About 80% of my meals have gone plant based now."
The UFC superstar has been a big fan of meat in the past -- he even promoted the ButcherBox meat company on his Instagram in 2019.
But Jones tells us he's switching things up for his UFC 247 fight against Reyes -- and decided to cut a bunch of animal protein out of his diet this time around.
