Weight Loss & Weight Gain

Rob Kardashian and Blac Chyna look like their weekly cheat day has become cheat DAYS -- they started their day by pulling through a McDonald's drive-thru for breakfast.

No word if they got any hash browns (wouldn't blame 'em) ... but we can see they got OJ. Not the worst diet slipup, but the sugar could be an issue.

In the last month they've hit up a couple of In-N-Outs and even pulled over for ice cream on the side of the road.

As they say, quitting is easy ... when you've done it a hundred times.

Rick Ross has something in common with Rob Kardashian ... they're both wasting away, but there's one major difference -- Rozay isn't cutting back on his chicken wing intake.

Sources close to Rozay tell us he's determined to lose the lbs he packed on after his arrest for assault and kidnapping -- so, he's back on his RossFit program -- which requires daily workouts.

It's working. He's already down more than 60 lbs, and the weight loss was obvious in his recent Snapchat.

Our sources say Ross used to scarf down a huge plate of food before bed, but now he's eating earlier in the evening ... and he's eating more fruits, veggies and drinking water instead of soda. The boss is still cheating though. We're told he's still gotta have wings from his Wingstop restaurants.

Somebody get Eddie Lacy some tape ... 'cause the dude is RIPPED UP!

Check out the GB Packers running back proudly displaying his guns in a tank top at LAX this weekend -- showing everyone he's been busting his ass in the gym this offseason after his coach called him out for being overweight.

We broke the story ... Lacy hooked up with the creator of P90X back in February (after the guy came on "TMZ Sports" and offered to whip Lacy into shape) ... and you can already see the results.

Rob Kardashian losing weight is now a cottage industry, and not just for Blac Chyna ... because we've learned a couple of fitness companies are pitching in too.

Kardashian's said his goal is to drop another 40 to 50 pounds in 5 weeks, and reps from Hydroxycut and Quest Nutrition are ready to ship him boatloads of their products to help him reach that goal.

A rep from Hydroxycut says they want to hook him up with a weight loss pill called Black -- a nice 1-2 punch with Chyna's workout regimen. Meanwhile, Quest says it's interested in helping Rob pack on some muscle with protein powder, chips and bars.

Swag ... the true Hollywood diet plan.

Rob Kardashian has lost at least 50 pounds ... and he says he's now halfway there.

Claudia Jordan's got Amy Schumer's back -- be it size 6, 7 or 8 -- in the comedian's weight war with Glamour magazine.

Claudia weighed in on the debate about the mag including Amy in its plus size edition. Schumer's pissed and CJ agrees ... the numbers just don't add up, but she's not surprised.

Watch her go off on Glamour for more than just weight.

Bonus: Claudia reveals why she's gonna be plus size soon. Think green.

Rob Kardashian and Blac Chyna weren't very talkative at LAX Friday morning ... that is, until the topic turned to food.

Our photog asked Rob about his recent stops at In-N-Out Burger ... he's hit the fast food joint TWICE in the last week, while supposedly on his strict "no cheat days" diet.

Sure, Double-Double's are delish but Rob's got another good reason for digging in.

He's definitely slimmed up ... but Eddie Lacy says he refuses to put an exact number on his weight loss because "I don't do scales."

The Green Bay Packers RB touched down at LAX this weekend -- so, we had to ask about his off-season workout regimen with P90X creator Tony Horton.

Lacy says he's feels great ... and he doesn't need a stupid scale to prove it.

But at some point, the Packers are gonna make him get on a scale right??

Mama June's going under the knife to find a safer weight loss solution ... after falling unconscious multiple times.

We're told June is set to go in for gastric sleeve surgery later this month, and hopes to lose at least 80 more pounds. She's been on a crusade to slim down so she'd be healthy enough for the surgery. She's already dropped 90 lbs.

We're told "sleeve specialist" Dr. Michael Feiz in Beverly Hills will perform the operation.

TMZ broke the story ... June was hospitalized two weeks ago after collapsing. Although doctors couldn't pin down the problem, we're told they suspect she was pushing her dieting too far.

Rob Kardashian and Blac Chyna want you to believe he's in the throes of a crash diet, but get a load of his carbo-load and the booze to help wash it down.

Rob and Chyna hit up Benihana in Encino for lunch Tuesday ... and our Far East sources tell us they wolfed down a "whole bunch of sushi," as they sipped on a couple rounds of sake and mimosas.

Rob's had issues with substance abuse, and Chyna's fresh off a daytime arrest in Texas after getting wasted at the airport.

That said ... it looks like Rob's losing a bunch of weight.

The Benihana diet. Who knew?

Jared Fogle is a lot of things ... but one thing he's not is fat.

Fogle has reportedly been on a downward dietary spiral at Englewood prison in Colorado ... supposedly heavier by 30 lbs and counting, courtesy of the prison commissary.

Fogle's attorney, Ronald Elberger, tells us it's all a lie ... his client hasn't gained a pound in prison ... to the contrary he exercises regularly on the prison track.

He's eating standard prison fare, including soups, burgers, beef stew, BBQ chicken and enchilada casserole. There are reports he's scarfing down Honey Buns ... Elberger says not true.

The lawyer says Fogle is actually doing quite well in the first few months of his 15 year sentence.

Rob Kardashian is showing glimmers of a toned body, judging from what looks like some pretty muscular calves.

Rob arrived at LAX Monday and his body was almost entirely shrouded in workout gear, but there are certainly signs he's dumping the weight faster than his sister 86'd Kris Humphries.

Lookin' good.

Finally, hard evidence GB Packers running back Eddie Lacy took up the offer to train with P90X creator Tony Horton -- and we gotta say ... the dude looks like he's already getting results.

Check out the photo Tony's training pal Bobby Stephenson posted on Facebook -- showing Eddie and Tony after a workout with the caption, "Crushing Shoulders and Arms P90X Style."

Packers coach Mike McCarthy had said he wanted Lacy to shed some serious LBs before next season -- and that's when Horton volunteered his services.

Check out what Lacy looked like 31 weeks ago ... looks like Lacy is taking the workout plan very very seriously.

Oprah Winfrey took a very unwanted bath after Weight Watchers stock took a huge hit.

WW shares dropped a whopping 20 percent when the company reported a 21 percent drop in fourth-quarter net revenue -- which means O's bank account is about 24 million bucks lighter today.

Cry not for Oprah -- she's still reportedly cleared nearly $75 million since buying a 10-percent stake in the company and joining its board. The stock doubled the day her deal was announced ... but it's looking more like your typical yo-yo dieter now.

Chris Pratt says he's not as fit as you think, but the secret will soon be out because he may just go back to being fat Pratt.

We got Chris out at LAX Wednesday afternoon and he was super excited about "Guardians of the Galaxy 2." But he's also a little bummed about his favorite alcoholic drink that's not on the diet.

Blac Chyna went ham on Kris Jenner and her family for daring to help stock Rob Kardashian's new kitchen with healthy food.

Check out the video ... Chyna scoffs at the food choices, including fat free sorbet, I Can't Believe It's Not Butter, wheat tortillas, oatmeal and quinoa. BTW ... there's also pizza crust mix, although it's wheat.

TMZ broke the story ... Kris helped Rob buy a house in the Calabasas community where his sisters live. It seems Chyna's none too happy his family is back in the picture.

Our Kardashian sources tell us they think it's despicable Chyna's making fun of Rob's family for trying to help him beat his diabetes and weight issues.

To Chyna's credit, Rob has lost around 40 lbs on her watch.

Rob made it clear which sides he's picking between Chyna and his fam with a very descripitive IG post late Tuesday night ...
