Snooki, Khloé Kardashian, and More — See the Most Shocking Celebrity Weight Losses of All Time

Snooki

The 28-year-old has lost 50 lbs since her time on Jersey Shore.

“[Jwow's] proud of me that I’m fit… because she always had to drag me to the gym,” she said. “Now, I’m like ‘Let’s go to the gym.’ … We’re kind of like on the same playing level now.”

Zach Galifianakis

The 46-year-old claims that he dropped major lbs after he stopped drinking!

"I stopped drinking and I just kind of put the weight off…I was having a lot of vodka with sausage…delicious but bad for you," he said. "I was getting into too much trouble with the drinking, so I just kind of stopped."

Khloé Kardashian

The 31-year-old has lost 40 lbs so far.

"I definitely think the physical and the mental go hand in hand," she has said. "I feel so good in the gym that it [affects] the rest of my day. It's a healthy addiction. It's like buying your sanity!"

Melissa McCarthy

The 45-year-old has lost 75 lbs by being less hard on herself about her weight.

"I truly stopped worrying about [my weight]," she said. "I stopped over-analyzing, over-thinking, over-doing anything. I kinda went back to when I was pregnant and I just stopped constantly being worried about it and I think there's something to kinda loosening up and not being so nervous and rigid about it that, bizarrely, has worked. I could've figured that out before 44, but whatever."

Adele

The 27-year-old has dropped a considerable amount of weight, but says that she's not trying to become a size zero.

"I'm not, like, skipping to the f—ing gym. I don't enjoy it. I do like doing weights. I don't like looking in the mirror. Blood vessels burst on my face really easily, so I'm so conscious when I'm lifting weights not to let them burst in my face. And if I don't tour, you'll catch me back down at the Chinese!" she has said.

Sam Smith

The 23-year-old has lost nearly 50 lbs in the past few years, which he accredits to be bullied about his weight.

"When someone calls you gay, there's not much you can do about that because I am. Whereas, if someone calls you fat, there is something you can do about that," he said.

Shonda Rhimes

The 46-year-old lost 100 lbs thanks to her kids!

Miranda Lambert

The 32-year-old dropped 20 lbs by adopting a healthier lifestyle.

“I live big and happy. I go out with friends all the time,” she said. “I love to drink and eat and enjoy things. It’s important to me. I want to be healthy and fit, but it shouldn’t be that big of a damn deal.”

Kelly Osbourne

The 31-year-old lost 70 lbs, and she credits her weight loss to hard work.

“I get in a solid half hour of cardio daily, usually intervals on the treadmill, and whatever else I feel like that day — weights, yoga or pilates," she has said.

Jennifer Hudson

The 34-year-old dropped 80 lbs.

“I throw the pancakes across the room! I don’t let the food intimidate me,” she has said.
“If it’s too much, I just get rid of it, but I make sure to watch what I put in my body. And I make sure I know what it is. It’s all about portions, for the most part. I just take care of myself in that way, being more conscious. I don’t work out a lot, but I do like to be active. Simple as that.”

Like especially me, I’m such a creative person that I yo-yo. So sometimes I’m more fit and I get into kickboxing hardcore. And then sometimes I don’t, and I’m like … I’d rather have wine.”
