'Iron Mike' shocked the world earlier this year when he announced a boxing return was in the works.
The former world champion then got fans excited after sharing training footage that proved he hadn't lost his famous raw power.
Speaking to FightHype, the 54-year-old has revealed exactly how much weight he's cut.
"I just came out to my partner's house. She lives out here, [Dana Point, California]" Tyson explained. "We've just been training, boxing, and it feels great man. I come from 289lbs to 220lbs. And I feel good."
It's a huge turnaround for the 'Baddest Man on the Planet' after ballooning to nearly 400lbs during the lows of his post-boxing career.
He revealed to ABC back in 2013: "I may get up in the morning and do an hour of cardio. I do StairMaster or treadmill or TreadClimber for an hour and then I go to the gym around 7:30 and ride the bike for an hour and do my ab exercises, my chest and my light weights. Then I start it over again the next morning.

"Because I am a fat kid. If I don't continue to watch my diet and exercise and take care myself I balloon to a lot of weight. I've always been a fat kid. I was 380lbs now I'm 240lbs."
Tyson recently shared an image on social media of his ripped physique and it could be the best he's ever looked.
He looks ready to return to action and recently claimed he will be 'unstoppable' when he steps inside the ring once again.
"That's all I've been doing, getting into shape," he said on a #PlayApartTogether live stream on Facebook.
"I feel unstoppable now. I feel the same [as when I was in my prime] again. The gods of war ignited my ego and want me to go to war again.
"Imagine if I went out there and fought and I could help all these people we talked about."
