The Wildest Celebrity Weight Loss Transformations

Surprisingly, celebrities are just like regular people in a lot of ways. One of those ways is that many celebs struggle with their weight, yo-yo-ing up and down on the scale over the years. The celebrities on this list have lost a significant amount of weight. Some have gained, lost, gained, and then lost again. Others have kept the weight off for good. Read through the list and see if your favorite celebrity is here.

Zach Galifianakis


Zach Galifianakis is best known for his role as Alan in The Hangover. Since then, he has made some lifestyle changes to lose weight. He has stopped drinking, walks a lot, and eats a healthy diet. You can hardly recognize it from his rise to fame and let’s face it, he’s hot now.

Zach really emphasizes the role that giving up alcohol played in his weight loss. “I stopped drinking and I just, kind of, put the weight off,” he told Men’s Health. “I was having a lot of vodka with sausage. Delicious, but bad for you.”

Christina Aguilera


Christina Aguilera has had a bit of a public struggle with weight. When she first became famous, she had an awesome body. But over the years, she gained some weight, which happens when you have kids.

Now she has adopted a new and healthier lifestyle that includes yoga for a fit body. She also uses a meal service called The Fresh Diet that keeps her food intake around 1,600 calories a day.



Raven-Symoné is another young actress who has had a public struggle with weight. A nutrition expert helped Raven-Symoné lose a lot of weight and live like a new woman. She eliminated all fast food from her diet, which is a major reason she was so successful at losing weight.

The starlet had always had a positive self-image but decided to lose weight to silence her critics. She sat down with Oprah and admitted, “I lost weight to keep them people from talking to me. I got tired and irritated.”

John Goodman


John Goodman is probably best known for his role in Roseanne, as Roseanne’s husband. Their weight was even a frequent topic on the hit ’90s show.

He had an amazing transformation when he started eating healthier and exercising on a regular basis. Like Zach Galifianakis, he also gave up alcohol. “It was the answer for a lot of problems,” he told David Letterman. “I hit it hard for 30 years.” These changes helped him lose over 100 pounds.

Now 39-years-old and a mother of three, Simpson weighed a reported 240 pounds in 2019. She reached her heaviest weight after her third child and went to work burning it off. Her personal trainer Harley Pasternak had her start by walking 14,000 steps daily and eating a healthy diet. Pasternak told Women’s Health that Simpson’s weight loss was the most exciting client transformation of her career.



Remember Snooki from the Jersey Shore? Ya, me either. But she has gained some popularity and is a celebrity after giving birth to her son. Not only did she lose her baby weight, she lost extra weight on top of that.

How did she do it? “I go [to a trainer] four times a week, and we do legs, arms and everything,” she told People magazine. “And after every one-hour workout, I do an hour of cardio.” Wow, that’s dedication.

Tom Arnold


Actor Tom Arnold gained quite a bit of weight after starring in True Lies with Arnold Schwarzenegger. Tom started going to the gym six days a week, he cut back on carbohydrates, and began keeping track of his calories.

He didn’t follow any specific diet plan, just stuck to some general guidelines such as eating breakfast every day, staying fueled with small snacks (his faves are 100 calorie packs of chocolate almonds), and skipping carbs with dinner.

Ricky Gervais


Ricky Gervais is a hilarious UK comedian (and creator of the original version of The Office!). He used to struggle quite a lot with his weight until he started doing about 45 minutes of a cardio workout and 20 minutes of a weight workout at his house. He claims he hasn’t changed his diet at all and still drinks what he wants.

After losing 40 pounds with his girlfriend, Jane, he joked that “It wasn’t so much about the weight. It was more that I was a fat, lazy, out of shape slob.”

Chris Pratt


This was quite a transformation to see! Chris Pratt rose to fame while playing the chubby character Andy in Parks and Recreation. He was never a really fit guy, until his Guardians of the Galaxy role.

He lost an astonishing 60 pounds (in just six months) by going to the gym on a regular basis. His workouts include running, boxing, swimming, P90X, and kickboxing. He also made sure to drink tons of water.

Perez Hilton


Perez Hilton knows everything that is going on in Hollywood — gossip is his job! He was having trouble with the single life so lost quite a bit of weight by adopting a holistic lifestyle. Perez says along with the physical transformations he has also had a mental transformation so he is more aware of his energy in the universe.

“I’ve lost more than 70 pounds and I’ve worked for it, he told Shape. “I’ve done it the old-fashioned way, slow and steady, by eating healthily and exercising regularly. And I feel wonderful!”

Actor Jorge Garcia became a household name on hit shows like Becker, Lost, Alcatraz, and Hawaii Five-0. He had to lose 30 pounds for his role as Hugo Reyes in Lost, but he gained it back (and then some) after the series wrapped. Jorge eventually reached 400 pounds.

He tried many different diets with no luck until adopting veganism. It drastically improved his quality of life and he soon lost 100 and continues to lose more. Jorge maintains his healthy lifestyle today and looks terrific and happy.

Rosie O’Donnell


In 2013, Rosie O’Donnell underwent surgery to lose weight. She has been overweight most of her career, so it is possible she just needed a little extra help. She had a gastric sleeve put in place and lost 64 pounds because of it. Rosie says the weight loss has helped her change her life for the better.

She joked with PEOPLE that at her heaviest, she felt “like the Green Bay Packers’ front line, know what I mean? But it’s hard. I used to buy stretch pants size 11, 12. I’d stretch them into a 20. It didn’t matter, because the tag said 12 and that’s what counts.”

Jonah Hill


Jonah Hill has had a public battle with weight and has been compared to the buff actor Channing Tatum a lot, since they were in 21 Jump Street together. Jonah gains weight, then loses it, on a regular basis.

In 2018, showing off a newly-svelte body, he opened up to Ellen about his weight loss. “I wish there was some crazy thing that I did, like a pill or a genie or something, but I went to see a nutritionist, and he told me what to eat to change my habits and stuff,” Jonah said.

Kirstie Alley

Kirstie Alley gained quite a lot of weight after she played in the Look Who’s Talking movies. She was hardly recognizable. She was fed up with how she looked, so she used the Jenny Craig program to lose 50 pounds. Kirstie became a spokesperson for the company.

She once had this to say about her relationship with food. “I always joked that my holidays lasted from Halloween to New Year’s Eve, and maybe even into Valentine’s Day. I would think it was okay for me to eat whatever I wanted during those months.”

Khloe Kardashian

Formerly known as the heaviest of the Kardashian clan, the youngest of the sisters has recently revealed a more svelte figure. Khloe attributes the weight loss to her new-found love of exercise and eating a balanced diet, which she discovered as she was going through the process of a difficult divorce with ex-husband Lamar Odom.

Khloe’s dedication to a healthier lifestyle has paid off. In fact, she was so into working out that she was able to drop her pregnancy weight after giving birth to daughter True in April of 2018.

Kelly Osbourne


Kelly Osbourne basically grew up on television, on her family’s reality show The Osbournes. Growing up in that household looked somewhat stressful, so it is no wonder her weight went up and down.

Honey Boo Boo

Mama and Boo Boo weight loss

When her mother “Mama June” dropped a whopping 300 pounds, she was inspired to encourage Honey Boo Boo to lose weight as well. Alana “Honey Boo Boo” Thompson was not too enthusiastic about the idea, as supportive as she might be about her mother’s healthier weight.

However, in January of 2018 June sat down with ET and said that her then-12-year-old daughter had lost around five pounds by trying to eat healthier. “Alana actually went on a no-grease diet and she’s been, actually, doing pretty good with it,” June said, adding that Alana “doesn’t eat fried food” and is “trying to cut back on soda. That’s something she did [and] that I had [not] done.”

Seth Rogan


Seth Rogan lost 30 pounds for his role in The Green Hornet. It only took him 10 weeks to lose this weight, so it might not have been the healthiest of methods. However, he got fit for the movie and he looks pretty darn good!

Tyra Banks


Supermodel Tyra Banks gained some weight over the years, and it is no secret she has struggled with it, being in the public eye and all. She lost weight using a nutritionist and the Paleo diet and now says she has more energy and feels good about herself.
