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.

"I switched up my diet a little bit, I started eating plant based," Jones says.

"Cardio feels great, I’m lighter than I normally am. Normally I weigh at least 222 around this time. Right now I’m already 215. So I’m ahead of schedule majorly in my weight cut, which just allows me to focus on happiness and relaxation, and I just feel perfect."

Jones says he's laser-focused and ready to fight on Feb. 8 -- and is gunning for a highlight reel-style knockout -- but as long as he gets the "W," that's all that matters.

"It’d be nice to make WorldStarHipHop for some awesome KO, or make TMZ for some awesome KO. But that’s not really my style."

"I feel like when you go out there and you tell people, ‘I’m gonna knock this guy out right away’ and then you find yourself going into the 4th round and you still haven’t gotten that KO. You start panicking in your head a little bit when your plan is going wrong."

Bob Harper says what makes the 'Biggest Loser' reboot a big winner is what happens AFTER the contestants go home ... when the real work begins.

The host of the new 'BL' was on "TMZ Live" Tuesday, and while they're still going to have weight loss competitions ... he says the contestants will also be getting a huge helping hand whenever their time on the show ends.

The fitness guru also emphasizes the reboot's done away with "temptation challenges" and vote-offs. Bob explained there's a concerted effort to give contestants the necessary tools to continue a healthy lifestyle at home and on their own.

Arguably, that's the toughest part for most of the 'BL' cast ... according to Bob. The show's now airing Tuesday nights on USA and, overall, he says you can expect a "kinder, gentler" approach to slimming down.

Aldon Smith has cleaned himself up and is laser-focused on getting back in the NFL, so says Jay Glazer who tells TMZ Sports ... the former All-Pro deserves a 2nd chance.

The 30-year-old defensive end was a MONSTER in the league before substance abuse issues and domestic violence allegations derailed his career.

But, Glazer says Smith had an epiphany -- and made a life choice to turn his life around, starting with joining Jay's Unbreakable gym in West Hollywood.

"Aldon's great because Aldon's been working out with our [military veterans] in our MVP program every single Wednesday night," Jay said.

"Aldon has been sober for a while and he's been helping a lot of our vets with their sobriety."

Smith - who hasn't played a down in the NFL since 2015 -- is now trying to show NFL teams he deserves another shot in the league ... and Glazer believes he's earning it.

"We've given a lot of guys second chances. He deserves it as much as anybody I've been around," Jay told us at his GlazerPalooza event at Prestige Imports Miami, where a bunch of SICK exotic cars were on display!

The event benefits Jay's MVP charity which helps military vets and athletes who are dealing with mental health issues.

Jay says Aldon -- who set the 49ers franchise single-season sack record in 2012 (19.5 sacks) -- is currently at a solid 285 lbs and SHREDDED.

"He is a freak if nature."

Actor Kumail Nanjiani didn't have to make a New Year's resolution, because he's stayed jacked!!!

Kumail was hangin' with a friend Friday at a restaurant in the Los Feliz area of L.A., and it's pretty clear from the pose -- he hasn't lost an inch of mass or muscle.

The 41-year-old stunned everyone with his chiseled pic ... displaying his washboard abs and super vascular arms. He got ripped for his new flick, "Eternals" ... which is set for release in November.

As you know ... Kumail is best known as a nerdy computer geek on "Silicon Valley," which ended last year. During the last season, the nerd's arms were bulging out of his shirt. His career hit a new level in 2017 with his movie, "The Big Sick" -- a true story about his wife.

Hollywood relationships can get weak ... but these hot couples -- with some extra encouragement from their partners -- are making sure they always put the work in to stay strong!

From famous faces such as Chris Hemsworth and Elsa Pataky, Jennifer Lopez and Alex Rodriguez, Adam Levine and Behati Prinsloo, to Kelly Ripa and Mark Consuelos it seems like the hard work has been paying off!

These hot couples are on top of their game ... Dive into our gallery of celebrity workout couples to see all the hot pairs making sure they are at their lookin' good together!

Troubled NFL star Aldon Smith isn't giving up his dream of getting back on the football field ... 'cause he's training like crazy in hopes of making a return to the league.

30-year-old Smith hasn't played a down in the NFL since 2015 due to a variety of issues including substance abuse, a hit-and-run and domestic violence allegations.

Before the off-the-field issues, Smith was one of the most dominant players in the league -- he was a 1st Team All-Pro in 2012 when he recorded 19.5 sacks ... setting the San Francisco 49ers single-season franchise record.

Young Thug knows how to motivate the guys in his crew -- offer up a fat stack of cash ... and watch 'em go!

The "Hot" rapper was clowning around with his boys Thursday evening outside the Sunset Marquis in West Hollywood when things turned into a fitness challenge ... as they often do.

Thug bet one of his pals he couldn't run up and down the street -- which is on a fairly steep hill -- and pulled out his money to show him what was at stake.

The guy accepted the challenge, and despite getting roasted for his running form -- or lack thereof -- Young Thug ponied up the dough. However, he made sure to rub it in by running the hill himself ... without all the huffing and puffing.

What makes Thug's running even funnier is the fact he's rocking super-skinny jeans

BTW, he's got a show Friday night at Avenue LA. No word if he's jogging to it.

Jake Paul's pulling out all the stops for his big return to the ring ... and the footage from his training sesh with boxing legend "Sugar" Shane Mosley is INTENSE.

Of course, Paul's fighting fellow YouTube superstar AnEsonGib during a Super Bowl week extravaganza ... and JP's been training like an animal at Mosley's gym in Big Bear.

The footage -- part of DAZN's 40 Days doc -- is pretty impressive ... and despite Paul wanting to avenge his brother's loss and take on KSI, it's clear he's laser-focused for the January 30 fight.

KSI's played a huge role in making this fight happen ... continuously bating Jake until he accepted the match.

“I don’t like Jake and I think the whole world doesn’t like Jake,” KSI says.

“If he does manage to get past the Big Gibber then yes, I will fight Jake. 100%. But, that’s not going to happen, I don’t think he’s ready for Gib at all and that’s going to show on Jan. 30. I think Gib wins this hands down and that will be the end of the Paul brothers.”

Talk about the ultimate flex ... Giancarlo Stanton showed off ALL of his muscles in front of smokin' hot model Adriana Lima -- BY BENCH PRESSING HER!!!

The video of the Yankees superstar in the gym is insane ... he laid down on his back, grabbed Lima by the legs and the armpit -- and benched her AT LEAST 4 times!!!

It's unclear why a normal barbell and plates weren't enough for the outfielder ... but Lima sure seemed to dig it -- the supermodel was smiling the whole time!!

Of course, the feat ain't exactly tough for Stanton ... he's known as the strongest guy in the league -- so benchin' a former Victoria's Secret model was clearly NBD.

But, just to prove the guy could still lift some serious weights ... he showed off his skills with a hammer and a tire -- and yeah, dude's got the muscles!!

Dr. Oz is firing back at Mark Wahlberg's cardiac arrest crack -- and as it turns out, the doc's actually got some jokes of his own ... plus nifty visual aides.

DO took to Instagram Saturday to respond to Mark's own video from a few days ago, where he accepted Oz's no-breakfast/one-legged push-up challenge and then joked the guy would probably need a defibrillator by the time Marky Mark was done with him in the gym.

Well, Dr. Oz seems to have one-upped him -- rocking real scrubs and showing off an actual defibrillator in what looks to be a real hospital ... not to mention giving a demonstration.

Oz even takes some shots at MW, saying he's probably used a fake defibrillator in front of the camera -- but in the real world, only one of 'em knows how to use it ... and it ain't Mark. He goes on to call out Mark's "full stomach" and show muscles ... doubting they work as advertised. It's funny, Dr. Oz is confident Mark will be the one passing out.

This is just the latest sling in what's become the weirdest/most awesome celeb feud of the new year. That said, we're ready to see some action here ... 'cause talk is cheap.

Taylor Swift likes her workouts solo -- as in she doesn't just book a trainer, she books a gym -- sorry Justin Bieber.

Here's the deal ... Justin was at Dogpound Gym in West Hollywood with a bunch of people, but then Taylor and her crew rolled up.

We're told everyone -- including JB was asked to get the heck out of the gym -- because Taylor had an appointment. Justin's security team was approached and asked to leave, but JB's team held firm and said he was going to finish his workout before taking off.

We're told Justin, who did not have an appointment, finished -- although he was mostly goofing around and dancing -- and left ... but he had no idea it was Taylor who had requested the gym be cleared. Once he left, everyone who remained was asked to leave.

One source connected to the gym tells us Taylor did indeed have an appointment with a trainer in the gym ... and the appointment was to train alone. Justin just happened to be in the wrong place at the wrong time.

JB gave fans a preview of his routine that day, spending quite a bit of time dancing in front of mirrors to his new single, "Yummy."

Here it is ... Conor McGregor and Donald "Cowboy" Cerrone stripping down and weighing in for their main event fight at UFC 246 -- and good news, they both made weight!

Conor and Cowboy both hit 170 on the dot -- perfect weight for their welterweight matchup Saturday night at the T-Mobile Arena in Las Vegas.

The last time McGregor fought, he only weighed 155 to fight Khabib Nurmagomedov for the UFC lightweight title.

But now, he's moved up in weight and he looks pretty good -- big, strong and UFC doctors say he's in the best shape of his MMA career.

As for Cowboy, DON'T SLEEP ON THAT GUY -- Cerrone holds the UFC record for most victories, most finishes and most fight bonuses!

Both fighters will next attend the UFC ceremonial weigh-in -- which goes down later Friday in front of thousands of fans. It's usually a chaotic scene. We'll have the highlights for you right here.

Rebel Wilson's gonna make it hard for "Pitch Perfect 4" (y'know it's gonna happen) producers to cast her as Fat Amy again, because she's shedding some serious weight.

The "Cats" star -- sorry, we had to mention that -- has been focused on her health and weight-loss for awhile now, and these new images of her putting in work at the gym ... show the progress is real in 2020.

Rebel's been sharing her progress for the last 10 months, and even credits the filming of "Cats" for aiding her weight loss. So, there IS a silver lining to that disaster.

On January 2 she put herself all the way out there, saying ... "Okay so for me 2020 is going to be called “The Year of Health.” Rebel vowed to get exercise and avoid sugar and junk food and added, "Who’s with me in making some positive changes this year?"

Looks like Wilson's sticking to her plan so far, and her “transformation trainer,” Jono Castano, says she's been doing it 7 days a week.

Myles Garrett clearly believes he'll play football again ... 'cause the dude is still hitting the weights HARD -- benching 425 POUNDS in a workout this week!!!

Of course, Garrett's NFL future is up in the air ... the Browns star is still serving out an indefinite suspension for attacking Steelers QB Mason Rudolph with his helmet in November.

But, Myles apparently ain't concerned the ban will last too much longer ... he's lifting weights like he's going to be facing 300-pound O-linemen in the very near future.

Ya gotta watch the clip ... Garrett -- with internet fitness superstar Bradley Martyn spotting -- hits 425 pounds TWICE, and it's impressive as hell!!!

He also makes 100-pound dumbbells look like 45s in an upper chest workout, hits dips with ease and showed off with some weighted rows as well.

Yeah, guy's a beast!!

Garrett's training is just the latest sign his suspension might coming to an end ... remember, he didn't try to hide his face at all at a Los Angeles Lakers game earlier this month.

Someone's leaving in an ambulance, and Mark Wahlberg is positive it'll be Dr. Oz ... IF the good doc follows through with his push-up challenge ... to settle the great breakfast debate once and for all.

It all started out kinda funny, but Mark's no longer laughing, saying to Oz, "We got beef now. You don't want this smoke" -- making it clear he's down for whatever physical competition Oz wants.

You'll recall ... Oz threw down the gauntlet earlier this week when he told us he'd crush Marky Mark in a one-legged push-up contest ... all because Mark disagreed with Oz's controversial break-xit remark -- that we should do away with breakfast altogether!!

Careful what you ask for, Oz, 'cause Mark's dead serious -- "You could do your little 20 push-ups with one leg, your assisted pull-up. I'm telling you you'll need a defibrillator when I'm done with you!"

Dr. Oz is throwing down the gauntlet like we've never seen anyone do before -- daring to challenge shredded Mark Wahlberg to a physical fitness competition!!!

The so-called "BreakXit" controversy Dr. Oz started is NOT dying down ... and Monday in NYC he was prepared to go all-out to defend his belief it's time to cancel breakfast.

As you know, we got Mark out this weekend and he shot down the good Doc's theory. Turns out, Oz is taking that personally. He told us, he's reached out to Wahlberg for a sit down to come to some agreement about skipping breakfast.

And, get this ... he's also down for more than just talk the talk. Oz is challenging Wahlberg to a one-legged push-up contest -- and seems supremely confident he can beat the muscle-bound celeb without breakin' a sweat ... especially if Mark's got a bellyful o' breakfast.
