Kelly Osbourne's had to deal with plenty of loss -- about 85 pounds of body weight, that is!

The reality television star has managed to completely change her physique, and she's been open about the ups and downs in size she's experienced in the past.

We're going to look into what she's gone through to slim down ... and how a surgical procedure completely changed her life.

Osbourne's weight-loss journey kicked off in the late 2010s when she underwent gastric sleeve surgery, in which a portion of her stomach was removed from her body.

She remained enthusiastic about the results of the procedure years after it was completed, and described the surgery as "the best thing I have ever done" during an appearance on the Hollywood Raw podcast.

Osbourne pointed out, however, that going through with the procedure meant she had to change her mindset about health, and she recalled she went through "a year of stand-alone therapy to prepare myself for the surgery."

She went on to say she had to become more disciplined about both fitness and monitoring her food intake in the years since her surgery.

However, she's also expressed she truly doesn't care about outside opinions with regard to her procedure ... and told the podcast's host she doesn't "give a f*** what anyone has to say."

Osbourne's also been open about how her health was affected by her pregnancy -- she gave birth to her son Sidney in November 2022.

The reality television star developed gestational diabetes while preparing for the birth of her child -- who she shares with Slipknot member Sid Wilson -- and recalled she had to closely monitor her food intake in the months prior to her baby's arrival.

Osbourne told People she "didn't get to have the pregnancy where you eat whatever you want. It sucked. I was hungry for nine months."

After she gave birth to her son, however, she began to push the limits of how much weight she could lose to unhealthy levels.

Osbourne opened up about her postpartum period in an appearance on the Scheananigans With Scheana Shay podcast, and admitted she went "too far" with her weight loss.

While many of her fans surmised she had lost her baby weight through the use of Ozempic, the reality television mainstay flat-out denied the claims during an interview with Extra.

Osbourne said she'd put off the pounds the old-fashioned way ... cutting out sugar and carbohydrates, which caused her to shrink "rapidly."

The thing is, she doesn't judge anyone who turns to the celebrity-favorite weight-loss medication -- including her mother Sharon -- and sees the jab as an effective and modern method of slimming down in size.

Osbourne voiced her approval of Ozempic while speaking to E! News, and said she was a fan of losing weight "through something that's isn't as boring as working out."

Lizzo is boldy reminding haters that the 'Truth Hurts' ... 'cause she just stripped down to her underwear to show off her weight loss and detail exactly how she slimmed down.

Check out her dramatic before-and-after photos posted on Instagram Thursday -- she's got nothing to hide as she bares it all to flaunt her thinner frame.

In her caption, she put her foot down against those Ozempic accusations ... and said lymphatic massages have been a huge help with shedding 16% of her body fat -- specifically thanking spa owner Flávia Lanini for helping her stay on track with her weight loss and health journey.

Sharon Osbourne's no stranger to body modification, and many of her changes in recent years have been related to her physique.

However, the reality television mainstay has made no secret of the extremes she reached while changing her body.

We're going to take a look at just how far she's pushed herself in the past and see how her actions could impact her future.

Osbourne's been open about the causes of her size issues in the past, and she told E! News a longstanding eating disorder had been the root of many of her body-related concerns.

The wife of former Black Sabbath frontman Ozzy Osbourne recalled undergoing gastric band surgery, which restricted the top part of her stomach in an effort to reduce her appetite.

She's also undergone a sleeve gastrectomy, during which a portion of her stomach was removed in order to form it into a tube-like structure.

However, Osbourne -- who confessed her weight peaked at 230 pounds -- pointed out she doesn't judge anyone for turning to weight-loss methods ... including medications.

She went on to state that, while she had attempted exercising, she ultimately determined that she was "too lazy for that."

Osbourne has also been transparent about her use of the celebrity-favorite weight-loss medication Ozempic, which she started using in 2022.

Although she utilized the GLP-1 medication for a few months, she stopped taking the jab after she found herself in a place where she "couldn't stop losing weight," according to the Daily Mail.

Osbourne also admitted she couldn't "afford to lose any more" weight, as getting any lighter would be dangerous for her body.

She then described the weight-loss drug as "very dangerous" if used in excess, as she found it to be "addicting."

Osbourne added she wanted to warn teenagers away from using GLP-1 drugs, which are "too easy" to abuse.

While Osbourne's been clear regarding her feelings about Ozempic usage, she doesn't think less of anyone for utilizing the medication, and she told E! News users shouldn't view their use of weight-loss drugs as "a dirty little secret."

The reality television mainstay has since revealed she's come to terms with her body-related concerns in recent years, and claimed she was "through with the weight loss and all that cosmetic stuff" during an interview with The Guardian.

She did admit, however, that she had used what she described as "too much" of the GLP-1 medication, which left her in a position where she "can't put on weight."

Osbourne added that, after going through various physical changes and ceasing her use of the weight-loss drug, she had "finally become more accepting of my body, my looks."

Billy Gardell's weight loss has seen the formerly 370-pound-plus star slim down to a much more manageable number in the low 200s.

And the "Mike & Molly" star's also been open about how undergoing bariatric surgery has made all the difference in his fitness journey.

Here's how going under the knife completely changed the actor's life -- and how he's been able to keep off the pounds in the years after his procedure.

Although his health improved in the long run, Gardell wasn't always so gung-ho about undergoing a weight-loss procedure, which he revealed in an interview with People.

The performer stated that, while he put off any drastic weight-loss measures for an extended period of time, he reached a point "where it hurt to exercise."

The delay wasn't for lack of trying, either, as Gardell claimed he "tried everything" to lose weight before falling into a "yo-yo" cycle that saw him gaining and losing weight.

He then recalled reaching a point where he realized that "drastic" action was necessary to address his health concerns, although he admitted that he "chickened out" of bariatric surgery on several occasions.

Gardell went on to state he eventually developed type 2 diabetes and was on medication for the disease for a year and a half, which greatly displeased him.

The "Bob Hearts Abishola" star then expressed that the onset of the COVID-19 pandemic was what motivated him to get his weight under control, as his size made him more susceptible to the effects of coronavirus.

Gardell added that he didn't want to risk the possibility of being removed from the lives of his family, saying "the idea of not being here for my wife or my kid motivated my change."

The performer noted he had to become "humble enough to ask for help" in order to actually start his plans for surgery.

He then spoke about consulting with a doctor, who he said "changed and saved my life."

Gardell said while he was grateful for the experience, he did not want his fans to follow his exact path to a healthy lifestyle, and noted the surgery was the "right decision" for himself.

The actor has since opened up about the effects his procedure had on his immediate family -- some of whom didn't even recognize him at first!

Gardell made the admission during a sit-down with Entertainment Tonight and fondly recalled when he "first lost the weight, my wife thought a stranger was in the house."

He also spoke about meeting individuals in similar health-related situations, and said he advised them that following a weight-loss procedure, they needed to emphasize healthy habits in order to keep the pounds off.

The performer noted if "you're not willing to commit to the stuff on the other side, it's just gonna happen again."

Kathy Bates has become an example of self-determination paying off -- as she was able to drop an impressive 100 pounds over the past few years.

However, a lot of hard work went into her physical transformation, which was spurred by a harrowing health scare.

We're going to look into the "Misery" star's impressive weight loss and see why her newfound interest in wellness has greatly improved her quality of life.

Bates was diagnosed with type 2 diabetes in 2017, and she told People the disease had been prevalent within her family.

The performer told the publication several of her family members had been dealing with various complications from the condition, and her own diagnosis "scared me straight."

She stated that being told she was going to be living with the disease inspired her to start making changes in her diet and wellness routine.

Bates recalled having to completely switch up her diet, and admitted she "used to eat terribly," and at odd hours.

She remarked her niece had advised her she'd experience "an involuntary sigh" after becoming full, and she would stop eating after noticing the reflex.

Bates went on to tell the outlet that in addition to making changes with her eating habits, she started prioritizing her own fitness and became more serious about working out.

But she maintained she was committed to remaining independent while working out, and remarked she didn't want "anybody over my shoulder."

While Bates claimed that 80 out of the 100 pounds she lost were due to changes in her lifestyle, she admitted she shed the final 20 through the use of Ozempic.

The performer stressed that, although she was aware of claims her weight loss was achieved solely through her use of the celebrity-favorite medication, she wanted her fans to know she truly is dedicated to her health.

Bates remarked that the physical aspect of her lifestyle change "was hard work for me, especially during the pandemic."

The actress then expressed her life had greatly improved following her weight loss, as she became "capable" of working long days on set.

Bates added she'd become able to "do so many things that I couldn’t before" while working on the set of "Matlock," in which she stars.

Another benefit of her weight loss is the effects on the symptoms of her lymphedema, which causes swelling in various parts of her body.

The actress said she felt "such a thrill to be able to put my arm into a jacket and it fits."
