Losing weight can be a tough process filled with (literal) ups and downs. After quarantine, you may find yourself staring at a few extra pounds that weren’t there before.

But pandemic or not, struggling with body weight is one of the only things that celebrities face, just like the rest of us.

If you’re looking for some inspiration, or are simply curious, here’s a list of the most amazing celebrity weight loss transformations.

1. Adele

Adele has always been known for her incredibly powerful voice and moving lyrics—her appearance has never been central to her fame.

Nonetheless, in recent years, fans noticed that she had lost a significant amount of weight.

Lifting weights and circuit training make up the bulk of her exercise regime, and Adele is also rumored to follow the Sirtfood diet.

2. Rebel Wilson

Since 2020, Rebel Wilson has lost over 60 pounds through her new diet and exercise routine.

She follows the Mayr Method, which reduces dairy, gluten, sugar, and caffeine intake. She also exercises six to seven days a week, focusing on cardio, strength training, HIIT, and mobility.

Beyond these routines, though, she has also publicly stated that while she is happy with her body, she is still all about embracing balance and living a healthy life physically and mentally.

3. Khloe Kardashian

When the Kardashian family entered the spotlight in the early 2000s, Khloe Kardashian was often ridiculed by the press and public alike for the fact that she was larger than her sisters Kim and Kourtney.

She has since proven all her haters wrong.

The Revenge Body mogul has lost dozens of pounds over the years through regular grueling gym sessions (often documented on her social media platforms) and a high-protein diet.

4. Melissa McCarthy

Melissa McCarthy has reportedly lost over 75 pounds in recent years.

However, unlike some other celebrities who follow strict diets and workout plans to do so, her weight-loss journey was all about balance and freedom.

5. Jacob Batalon

Jacob Batalon, the beloved Marvel star and best friend of Tom Holland’s Spiderman, has lost 112 pounds since 2020.

He did so by working on his overall health, including establishing a proper exercise and diet regime and improving his relationship with food. Since then, he has lost weight and found mental clarity and joy.

6. Simon Cowell

America’s beloved and sassiest TV show host Simon Cowell lost over 60 pounds since his son Eric was born.

He cited his son as a contributing reason for his 60-pound weight loss, as he wanted to ensure that he could keep up with his active child.

A vegan diet and a generally active lifestyle are the main changes he made to reach his goal.

“I’m not a big eater,” he told The Sun in an interview. “I don’t enjoy it that much. I’d rather have a beer than eat, any day of the week.”

“Sometimes when we are going out for dinner because I know I’m going to hate the food, I have baked beans on toast before I go, then eat nothing.”

7. Jonah Hill

For a few years, Jonah Hill became somewhat notorious for both gaining and losing weight rapidly. From approximately 2011 to 2017, his weight fluctuated greatly over short periods of time.

Jonah Hill started his weight loss journey in 2011 and resumed in 2017 after gaining 40 pounds for his role in the 2015 movie War DogsJonah Hill started his weight loss journey in 2011 and resumed in 2017 after gaining 40 pounds for his role in the 2015 movie War Dogs (Credit: Jaguar PS / Kathy Hutchins / Shutterstock)

Looking back, he cited yo-yo-dieting as the source, which is a very common factor of fluctuating weight in celebrities and regular people alike.

However, in more recent years, it seems that Jonah Hill has gained a better relationship with food and has maintained a healthy weight.

8. Mama June Shannon

One of the most drastic weight transformations on this list, Mama June Shannon, mother of ‘Toddlers & Tiaras’ star Honey Boo Boo, lost 300 pounds thanks to gastric sleeve surgery.

To maintain her new physique, she now follows a regular workout plan with a trainer two to three times per week.

9. Jimmy Kimmel

TV show host Jimmy Kimmel became concerned about his weight after one of his guests, the famed Dr. Oz, stated that he was worried about him in 2010.

Taking the word of the renowned doctor to heart, Jimmy Kimmel began a diet of two protein shakes and a small dinner every day for eight weeks before moving on to a 2,000 calorie-per-day diet that allowed him to lose 25 pounds as quickly and safely as possible.

As of 2015, he is reported to follow a less-strict diet most days but uses intermittent fasting two days per week (eating only 500 calories) to maintain his weight loss.

10. Chris Pratt

Much like Jonah Hill, Chris Pratt has both gained and lost weight for his acting roles.

After deliberately gaining weight to play Andy Dwyer on Parks and Recreation, Pratt lost 60 pounds in six months when he was hired to be the main character for Guardians of the Galaxy.

To get into action-star shape, he cut out beer, upped his calorie intake to 4,000 calories a day, and drank tons of water to flush his system.

He also did a variety of exercises, including P90X, running, swimming and boxing, and worked with a trainer six days a week to enhance his physique.

11. Shonda Rhimes

The well-known and well-loved Shonda Rhimes has lost over 150 pounds throughout her years in the spotlight.

In 2017, she opened up about her weight-loss journey. She stated that her goal in losing weight through a combination of diet and exercise was not to fit into any sort of aesthetic ideal but for her health.

While the journey itself wasn’t always enjoyable, she wanted to be healthy and strong and listen to her body, which she could tell was not happy at her heavier weight. Cheers to both her happiness and health.

12. Drew Barrymore

Drew Barrymore has proudly spoken about her weight loss journey and fully credits her trainer, Marnie Alton.

Barrymore has publicly stated that Alton is both her teacher, trainer, and friend, who has encouraged her to truly push herself.

13. Jessica Simpson

After the birth of her third baby, Birdie, Jessica Simpson lost approximately 100 pounds.

She utilized the help of celebrity trainer Harley Pasternak to do so. Pasternak helped Simpson slowly ease into physical activity to avoid burning out.

14. Christina Aguilera

Back in 2013, Christina Aguilera lost almost 50 pounds. She even took time off from her gig on The Voice to really focus on her physical health.

The Voice coach cited having the extra personal time as an excellent way to heal both her physical and mental well-being.

Trying new foods, exploring new types of exercise, and embracing spiritual practices such as reiki all contributed to Aguilera’s weight loss.

Sources have reported that she did not follow a strict diet or workout plan but rather focused on reconnecting with her body and mind, and the weight loss naturally followed.

15. Tiffany Haddish

Throughout 2020, Tiffany Haddish worked hard and ultimately lost 40 pounds.

On her 40th birthday, she was not happy with her weight. That same day, she decided to quit smoking and start taking the gym seriously.

She subsequently joined a 30-day fitness program and started taking her diet and nutrition more seriously, which helped her lose 10 more pounds.

In her workout, she mainly focuses on plyometrics, cardio, and strength training and makes sure to eat lots of protein and veggies.

16. Janet Jackson

When Janet Jackson announced a tour at 54 years old, she knew she would have to prepare her body for the grueling hours and level of exercise required.

Her trainer, Paula Sybliss, helped Jackson prepare for the tour life just six short weeks after she gave birth to her daughter Eissa.

Through weight training with Sybliss and the immense cardio from dancing on a stage every night, Janet Jackson successfully lost 70 pounds by the end of her tour.

Overall, it seems that (sadly) there is no hidden secret to weight loss—at least, not that celebrities have revealed to the public.

While the methods vary, even among those with access to more resources and personal trainers than most people, all weight loss comes as a result of some form of a caloric deficit.

Whether this is achieved through a diet, exercise, or both is entirely up to each person’s preferences and capabilities. Even if you don’t have a world-famous acting role to prepare for, if these celebrities can do it, so can you.
