We’re no longer surprised when we hear that celebrities go on crazy diets to lose a few pounds (even up to 10 pounds) for a project or a special event. They do it, we do it, it’s hardly a newsflash. But we can’t help but be surprised when the weight loss is impressive and the effects seem to be long term. That’s truly inspiring because that means it’s not just a quick diet and extra hours at the gym for a few weeks, that suggests a lifestyle change, something that’s sustainable. So let’s take a look at some of the craziest and most impressive weight loss transformations. 

1. Adele

Adele has been an icon since her first album came out, and she was never fussed about weight. She came to fame as a chubby girl and we loved her. We loved her voice, her songs, her sense of humor and her attitude. Her weight loss journey likely started sometime during 2019, which is also the year she got a divorce. But while some might think her weight loss is a result of a divorce, the truth is that Adele has actually re-evaluated some things in her life and decided that she needs to take better care of her health for her kids. And let me tell you, the results are truly stunning. We still can’t stop admiring and swooning over her new figure. How did she achieve this? She hired a personal trainer and went on a Sirtfood diet. 

2. Melissa McCarthy

Melissa McCarthy has been many different sizes throughout her life, and she’s done weight loss in both healthy and unhealthy ways. During her time on Gilmore Girls she’s done a liquid diet for 4 months and lost a significant amount of weight, but now looking back she realizes how unhealthy and unsustainable that was. She felt starved and crazy and she says she would never do that again. Since then she’s managed to lose another 50 lbs by just loosening up and not worrying about her weight all the time, which sounds iffy, but it’s a known fact that stress can make your body hold on to extra weight, and minimizing stress and finding ways to relax can help lose weight. 

3. Jessica Simpson

Jessica had quite a makeover after the birth of her daughter. She lost about 100 pounds and fully credits her personal trainer for helping her achieve such mindblowing results in a relatively short time. She did this in 6 months. What’s also great is that it looks like the pounds are staying off and Jessica is looking stunning. 

4. Jonah Hill

For years we got used to Jonah Hill being that chubby funny guy we see in movies. But he definitely surprised us all when he decided to slim down in 2011. It was a very noticeable weight loss, and everyone was already congratulating him on his progress, but he didn’t stop there. He doubled down on his weight loss journey in 2016-2017 and he’s still in shape in 2022. Now he does Jiu Jitsu for fitness, taking all sorts of stylish risks with fashion and his appearance (getting tattoos, bleaching his hair), and living his best life.
