Weight Loss & Weight Gain

Kim Kardashian says she hasn't been in hiding since the birth of North West ... it's debatable.

Kim was leaving a Sherman Oaks restaurant when one of the photogs asked her how it feels to be out of hiding. Her response is interesting.

The Hollywood post-baby game is to dump a lot of weight before stepping out in public. It's been 3 months since the kid was born and we've hardly seen Kim. She's definitely trimmed down and is pretty much back to being herself.

No surprise ... she's mum on Lamar.

Christina Aguilera flaunted her hot new bod last night ... but it wasn't her body people are talking about ... it's her face -- because it looks ... well, different.

She didn't explain how she did it last night on "The Tonight Show with Jay Leno."

So we gotta ask...

Chaz Bono is the incredible disappearing man -- 'cause dude has nearly shed a whole Honey Boo Boo worth of lbs since dramatically changing his diet last year.

Chaz was barely recognizable as he was spotted in Los Angeles today ... walking around in shorts and a pretty tight tee.

Earlier this year, Chaz talked about how he dropped nearly 70 pounds -- not through surgery -- but through sticking to calorie-controlled meals ... and doing a ton of martial arts training.

Chaz's original goal was only to lose 50 lbs. -- so he's clearly blown that away.

Jessica and Kim K. ... take notes.

Ex-beauty queen Shanna Moakler knows all about quick weight loss ... because she just had 2.5 liters of fat slurped right out of her ... and TMZ has the photo to prove it.

Shanna stopped by Elite Body Sculpture in Beverly Hills on Tuesday for some quick body work -- a procedure called Airbrush Laser Liposculpture.

According to the EBS website, the doctor doesn't use a scalpel, but rather a circular-shaped device that leaves a scar that's smaller than a pencil top eraser.

We're told Shanna wanted some extra help tightening up her stomach ... because she's had a tough time getting back into pre-baby shape after birthing 3 kids.

After the procedure, the doc gave Shanna a jar of the removed lard -- which measured out to 2.5 liters of the fat stuff.

For all you metrically-challenged people -- 2.5 liters is equal to 84.5 ounces ... which is almost 3 Big Gulps.

The best part -- after Shanna lost the fat, she raced straight from the doc's office to Boa Steakhouse on the Sunset Strip and woofed down a big ol' juicy steak ... 'cause why the hell not?

Cincinnati Reds 2nd baseman Brandon Phillips is in deep-fried trouble with a pro-fat person organization after blasting a sports reporter as a "fat motherf**ker" ... TMZ has learned.

The National Association for the Advancement of Fat Acceptance (NAAFA) had their ears (and probably their mouths) open when Phillips went off on C. Trent Rosecrans during a news conference with Reds manager Dusty Baker.

Rosecrans -- who happens to sport a fuller figure -- had gotten on Phillips' bad side for criticizing his on-base percentage ... and while CTR was talking to Baker, Phillips interrupted and called him a "fat f**k" and a "fat motherf**ker."

Baker just sat there ... refusing to call out Brandon.

But the NAAFA is hungry for an apology ... and also probably pizza ... and meatballs ... telling TMZ, "[Brandon's] poor choice of words indicates that he may have missed the fact that verbal aggression and threats are bullying."

The org. says they're especially upset because the Reds participate in anti-bullying campaigns -- "Putting on an anti-bullying face then allowing the blasting of a reporter's body-size is not acceptable."

We've reached out to the Reds -- so far, no word back.

Dr. H from "Biggest Loser" doesn't just help fat people with their problems -- he dropped $5.5 million on a sick mansion in Malibu ... to help folks of all sizes change their lives!!!

The good doc -- Robert Huizenga -- purchased the 9,750-square-foot casa at auction in July. But we're told the place isn't for him ... Dr. H will be using it as a wellness retreat where people (with fat wallets) can focus on making lifestyle changes through fitness, meditation and yoga.

FYI: He owns another mansion-based retreat -- located in the Hollywood Hills -- focused on weight loss. We're told the Malibu site is NOT strictly about shedding lbs.

As for the primo pad -- five separate buildings, 10.2 acres, 7 bedrooms, 7 baths, 360-degree views of the Cali coastline, outdoor cabana, pond, and an infinity pool overlooking the ocean, according to our friends at Trulia.

FUN FACTS: Before "Loser" Dr. H was the team physician for the L.A. Raiders and once wrote a book that inspired Oliver Stone's flick "Any Given Sunday."

Jake the Snake has downward-dogged his way to a better life ... the wrestling legend sweated off nearly 70lbs doing an intense yoga program ... and now he's hoping to get back in the ring.

The program Jake's been on was created by fellow wrestler Diamond Dallas Page -- called DDP Yoga -- and we're told Jake's been doing it for about 9 months now.

Diamond Dallas tells us ... a year ago when he met Jake he was "over 300lbs, on the booze, pain pills and crack." FYI -- it's well known that Jake suffered from substance abuse for years.

DDP tells us, he started Jake on the program, doing 1 or 2 sessions a day and eating clean. He says Jake not only shed the weight ... but it helped keep him clean and sober for months.

DDP says Jake now has a new goal (other than acting) -- doing one more Royal Rumble.

Jake tells TMZ ... he's making that goal a reality, explaining, "I will never give up ... I want a life again and I am pursuing that. The Rumble will define it."

Now check out Jake transforming ...

As if re-gaining a bunch of weight wasn't bad enough, former "Biggest Loser" star Tara Costa is now being SUED for porking up again ... and it could cost her a lot of money, TMZ has learned.

FC Online Marketing -- which owns ILoveKickboxing.com -- has filed a lawsuit against Costa claiming it entered into a fitness promotional agreement with the reality star ... but she didn't hold up her end of the bargain.

The deal breaker ... FCOM says Costa -- who famously lost 155 POUNDS on "The Biggest Loser: Couples 2" back in 2009 -- had re-gained "far too much weight" in 2011 to represent the brand in photo shoots and public appearances.

FCOM says it paid Costa's foundation $45,000 in exchange for her image and likeness ... but since she got fat again, her image has lost all value to the company.

FCOM is now suing Costa for breaching the don't-get-fat agreement, demanding unspecified damages.

For what it's worth ... from Costa's recent Twitter pics, it appears she's back down to her fighting weight (or close to it) but FCOM insists the damage is already done. Attempts to reach Costa were not successful.

Disgraced chef Paula Deen has committed a far worse crime than using the N-word: she's committed MURDER ... of sorts ... according to Kid 'n Play rapper Chris Reed.

Chris is surprisingly forgiving of Paula's blunder -- he explains why (although, our guess is he hasn't seen THIS GEM yet).

Less than a year after gaining 30 pounds, Lady Gaga is back down to her fighting weight -- surfacing south of the border in Mexico this week with some friends ... in a sexy floral bikini.

You'll recall, Gaga struggled with her weight last year, telling Stylist Magazine, "I don't really care if [people] think I'm fat, because, quite honestly, I did gain about 30 pounds."

Gaga also underwent serious hip surgery a few months ago ... so that probably helped with the weight loss too.

A popular L.A. comic says she had to have 1,000 gallstones removed from her body all thanks to a Jenny Craig diet ... and now she's suing the weight loss giant claiming they knew their products were dangerous and did nothing to warn their customers.

Mara Shapshay -- who regularly performs at the Laugh Factory and writes for Glamour Magazine -- filed a lawsuit against J.C. this week, claiming she started Jenny in 2011 hoping to shed some lbs ... but developed serious medical problems about a year later.

In fact, Shapshay claims she was hospitalized with severe abdominal pain ... and doctors ultimately discovered roughly 1,000 gallstones in her body.

Mara says she was forced to undergo multiple surgeries and now suffers from fatigue, abdominal pain, nausea and vomiting ... and blames J.C. for a recent miscarriage.

But the worst part, according to Shapshay ... Jenny Craig KNEW its program could lead to gallbladder disease ... but failed to inform their customers of the risks.

Shapshay is seeking unspecified damage$$$.

It's the most famous crash diet in history ... the Master Cleanse ... but according to celebrity super-trainer Jillian Michaels ... it's dangerous for your body.

Michaels was out in Malibu this weekend, when we asked about rumors that Beyonce dropped the baby weight by going on a Master Cleanse ... a 10-day program where people are only allowed to consume tea and lemonade mixed with maple syrup and cayenne pepper.

"Don't do the Master Cleanse," Michaels told us bluntly ... "It's bad for you."

Back in 2006, Beyonce told Oprah she shed a TON of poundage by using the program for 14 days ... but now, Michaels insinuates Beyonce is more educated about the dangers of the Cleanse ... and HIGHLY DOUBTS the singer would ever do it again.

Despite being her usual lovely shade of orange, Snooki looks a lot lighter.

The 23-year-old "Jersey Shore" star appeared slimmer at an event in Atlantic City this weekend (left) than she was just over a year ago (right).

Gym, tan, cardio!

The 27-year-old hit the ESPYs last night (left) having shed a good amount of hair, scruff and weight from just over a year ago (right).

Hill credits the weight loss to working out and eating healthier -- insisting "it's important."

Suplee broke down his old-fashioned weight loss approach in L.A. yesterday -- telling us, he hits the road on the regular ... and even wears SPANDEX.

Obviously the actor hasn't just been spinning his wheels.
