While details on his weight loss are currently unknown, Gronk shocked fans when he showed up to the premiere of Showtime's 100 Percent: Julian Edelman looking noticeably slimmer, and without his signature muscles. However, it's totally normal for professional football players to lose weight after retiring and laying off their intense training and <a href="https://www.menshealth.com/nutrition/a19535249/tom-brady-reveals-insane-diet-in-new-book/" id="981962f8-4af5-32fe-aeab-f706c10eb113"> diets </a> .

9) Kevin McHale The Glee star was spurred to change his diet from stomach pain. I had been working through an intestinal/digestion issue that was eluding diagnosis and that really took a toll on me," McHale <a href="https://www.menshealth.com/weight-loss/a23065948/kevin-mchale-transformation-photos-and-tips/" id="06b6f00b-2bad-3359-afc1-e709ce1918c1"> told us </a> .

Also, less beer, more running. Im going to keep running one every other month for a while until I can do a 10K, he told People.

Three or four hours a day of just consistent, ass-kicking hard work, he <a href="https://www.mensjournal.com/health-fitness/how-chris-pratt-dropped-60-pounds-six-months/" id="a2b53b57-f62d-3512-a11c-bed487ba7649"> told Mens Journal </a> . According to the magazine, Pratts routine included P90X, running, swimming, boxing, kickboxing, and a triathlon. And a whole lot more water. I was peeing all day long, every day. That part was a nightmare, he said. NurPhoto - Getty Images

12) Ed Sheeran The singer-songwriter put on a <a href="https://www.menshealth.com/weight-loss/a19536612/ed-sheeran-weight-loss/" id="f2c15ccd-8327-3f70-a3e4-e99ed99382cf"> significant amount of weight </a> after a tour, he told Total Access on Signal 1 Radio. My diet was pizza and beer, he said, but because I was doing two hours a night I was really in shape. I stopped touring and carried on my diet of pizza and beer. Suddenly I didnt fit in anything. So Sheeran asked his girlfriend, a hockey player, to intervene. I did 10 minutes a day without fail: intervals of 30 seconds and 30 seconds sprinting, he said, The key is to not miss a day, so you dont have to do an hour." Kevin Mazur - Getty Images

13) Jonah Hill Jonah Hill was labeled the funny fay kid after Superbad, Jonah Hill has battled a <a href="https://www.menshealth.com/weight-loss/a19521612/jonah-hill-weight-loss-transformation/" id="63347de2-5e7f-3a6c-a91e-f398f2d0613b"> series of weight fluctuations </a> . We suppose it helps to have Channing Tatum as consistent co-star to finally get whipped into shape. "I wanted to get in better shape, Hill <a href="https://www.cnn.com/2017/06/19/entertainment/jonah-hill-weight-loss/index.html" id="f8d9ceb0-ad6a-3627-a693-6b85b894f819"> said on The Tonight Show, </a> so I called Channing Tatum and said, 'Hey, if I ate less and go to a trainer, will I get in better shape? Yes, you dumb mother****er, of course you will. It's the simplest thing in the entire world. Its more than just thatHill has apparently <a href="https://www.menshealth.com/fitness/a19545011/jonah-hill-weight-loss-boxing-workout/" id="bb4827f1-5481-35e4-a01d-b104241bab8e"> added boxing </a> to his fitness routine.

14) DJ Khaled DJ Khaled is definitely a big dudeso its doubly impressive that hes sticking to a Weight Watchers diet and lost at least 26 pounds so far. Its not about losing weight for him, but about staying healthy. I'm not in any race to get rid of weight, he <a href="https://www.menshealth.com/weight-loss/a19547052/dj-khaled-weight-watchers-weight-loss/" id="8862a122-7f03-3f85-ab78-a52c2920a6ff"> said in an Instagram post </a> . I just want to make sure I stay super focused and continue at being healthy. So far, its been nothing but a success. The freestyle program is doing real big, he <a href="https://pagesix.com/2018/02/01/dj-khaled-down-26-pounds-after-joining-weight-watcher/" id="d1b71f36-e688-358b-a79e-292172a2ddde"> told Page Six </a> . Its a real lifestyle because all you have to do is not go over your point [total]. And there are so many zero points [foods] in case you get hungry. I got the freestyle dance.

15) Dan Reynolds The Imagine Dragons front man looks jackedall in spite of the fact that he <a href="https://www.menshealth.com/fitness/a25584971/imagine-dragons-dan-reynolds-diet-workout/" id="0906d078-1038-36f3-a516-001a7aacf75e"> lives with a rare autoimmune disease, </a> ankylosing spondylitis (AS). It causes inflammation in the spine and can lead to pain in different parts of the body. The only thing that really helped him: diet and exercise. So in early 2017, he got a trainer and started working out one to three hours, seven days a week. It took over a year for him to go from skinny fat to totally shredded, but the results speak for themselves. Francesco Prandoni - Getty Images

16) Rob McElhenney Rob McElhenney was well-known as Fat Mac for at least a season on Its Always Sunny in Philadelphia. No longer. After being <a href="https://www.menshealth.com/entertainment/a21285961/its-always-sunny-in-philadelphia-rob-mcelhenney-jacked-fit/" id="f1ba21f6-a841-3c23-a064-adf5c6d97aad"> spotted at the LA Pride parade </a> with the body of a comic book hero, McElhenney came clean <a href="https://www.instagram.com/p/BnXtEz1BLFP/?hl=en" id="6946816b-b36f-33cd-a228-b2c1f6113695"> in an Instagram post </a> . Look, its not that hard, he wrote. All you need to do is lift weights six days a week, stop drinking alcohol, dont eat anything after 7pm, dont eat any carbs or sugar at all, in fact just dont eat anything you like, get the personal trainer from Magic Mike, sleep nine hours a night, run three miles a day, and have a studio pay for the whole thing over a six to seven month span. Sounds easy enough. Alberto E. Rodriguez - Getty Images

18) Jake Gyllenhaal A-lister Jake Gyllenhaal was never really overweight, but he looked absolutely cut in the film Southpaw to play boxer Billy Hope. To prepare for the role, Gyllenhaal enlisted the help of <a href="https://www.mensjournal.com/health-fitness/inside-jake-gyllenhaals-boxing-workout-and-diet-for-southpaw-20150731/" id="76415f0a-5a45-3694-a143-9172ca8f34b4"> boxing coach Terry Claybon </a> . His routine consisted of an exhausting amount of morning runs, jumping rope, drills, shadow boxing, tire flips, bag work, and more. As for diet, well, that was out the window. We trained really hard every day, all day, and you can eat a lot when youre in that mode, Gyllenhaal told Mens Journal. It was always high protein. I remember eating a lot of Chipotle.

19) Al Roker The Emmy-winning Today Show weatherman looks flat-out completely different than just a few years ago.

But he had a hard time keeping the weight off, regaining 40 pounds after turning to junk food during a stressful time. I went back, he said on Today. And I hated it. I know what I have to do now to keep that from happening again. That was a smart combination of diet and exercisebeginning with a 28-day cleanse. Hes stayed slim by eating whole, unprocessed foods that are high in protein and low in carbs. NBC - Getty Images

20) Josh Peck The star of Nickelodeons Drake and Josh might have been the funny chubby kid, but no longer. In 2006, he <a href="https://www.dailymail.co.uk/tvshowbiz/article-2198810/Drake-Joshs-chubby-child-star-Josh-Peck-reveals-buff-new-physique.html" id="9dd4fee6-1a3b-304d-a539-4be4b1193ce7"> said </a> , 'I made a conscious effort to lose weight because I knew I could be happier as well as being healthier.

21) Sam Smith Buttery voice? You better believe it. Buttery diet? We dont think so. British crooner Sam Smith dropped an <a href="https://www.popsugar.com/fitness/How-Did-Sam-Smith-Lose-Weight-44132560" id="ba0fd859-70a1-3891-a98f-e7ec43e3f52e"> incredible 50 pounds </a> in 2015 after a lifetime of emotional eating. "From a young age, food has controlled me, basically," he said to 60 Minutes Australia. When I was at school and wasn't having a great time or when music wasn't going very well, I would eat. When I felt lonely, I would eat. He credits nutritionist Amelia Freer for his incredible transformation. And hes keeping the weight off by going to the gym with a personal trainer at least <a href="http://www.billboard.com/articles/news/magazine-feature/7989309/sam-smith-interview-billboard-2017" id="786d9491-7fad-356f-ad2e-df78b4901415"> three times per week </a> .

22) Gordon Ramsay Hard to not over-ear when youre the host of Hells Kitchen. [My wife] Tana was not impressed with the way I was, he <a href="https://www.dailymail.co.uk/femail/article-5320041/Gordon-Ramsay-lost-four-stone-wife.html" id="73f06077-3a87-31c3-aeba-571e97217f3a"> told The Daily Mail </a> . I was overweight, 18 stone. I looked like a sack of s***. Fear of losing your wife is certainly a great weight loss motivator, and Ramsay enlisted the help of Will Usher, a former Army captain and member of the Royal protection squad. Ramsay wanted to do an Ironman race, so Usher put him through a regimen of swimming, rowing, core strength work, three-hour-long workouts on a gym bike, and outdoor foot racing. His top diet advice? Nothing fancyjust lots and lots of water. Rob Kim - Getty Images

23) Jimmy Kimmel Late-night star Jimmy Kimmel had always been a big guyjust watch a Man Show reruneating mostly <a href="https://www.goodhousekeeping.com/health/a48018/jimmy-kimmel-weight-loss/" id="748ee1c1-6f2c-3bd0-a572-cc072f93876e"> wings, pasta, and steak </a> in his younger years and going up to 208 pounds. In 2010, Dr. Oz spurred him to make a change. I'm worried about you, Dr. Oz <a href="https://www.mensjournal.com/features/the-weird-way-jimmy-kimmel-lost-the-weight-20151214/" id="247f3903-705e-3f23-ae71-29e1c8327191"> told him </a> . You're a young man. You have to take care of yourself. I was like, You know what? Dr. Oz shouldn't care more about my health more than I do. So he started occasionally, well, starving himself. People call it the 5:2 diet, he said, but I've been doing it since before it had a name. On Monday and Thursday, I eat fewer than 500 calories a day, then I eat like a pig for the other five days. Unorthodox, but it worked: the comedian dropped 25 pounds. Randy Holmes - Getty Images

It wasnt like, Eat this for 90 days and lose 20 pounds. It was: Eat like this for the rest of your life... 95 percent of the time, Im right on the money. He stopped drinking caffeine and alcohol, stopped unhealthy snacking, started exercising regularly, and the result speaks for itself: over 70 pounds dropped. Denise Truscello - Getty Images

25) Dr. Dre The rap legend and media mogul has been tight-lipped about his sudden transformation at the <a href="https://athleanx.com/blog/celebrity-workouts/dr-dre-bulks-up" id="13752fad-66bb-3c15-a199-0679887871b8"> age of 45 </a> .

26) Rick Ross Rapper and producer Rick Ross was always a big fellow until his startling 100-pound weight loss. Howd he do it? Simple: he learned how to balance his appetite with hitting the gym. Its all about the balance to me, Ross told <a href="https://abcnews.go.com/Entertainment/rick-ross-breaks-routines-maintain-100-pound-weight/story?id=39075445" id="33b5fa12-0713-3432-a0c5-a3920f2d1861"> ABC News </a> . I wanted to balance myself but still enjoy the things I love so if I lost weight one year, the next year it wouldnt be right back on me." Ross said he does Crossfit-like workouts at least four times per weekbut still enjoys wings at one of the many Wingstop restaurants he owns. Plus, healthy snacking: I try to throw in healthy snacks in between the meals, he said. That was really my trick, and slowing down the heavy meals as it got later in the day.

27) Alec Baldwin When hes not skewering the president on Saturday Night Live, Alec Baldwin likes to eat cleaner than he ever has. Diagnosed as pre-diabetic a few years ago, the actor was spurred to change his ways <a href="https://www.closerweekly.com/posts/alec-baldwin-weight-loss-165177/" id="f44280ff-3460-35ce-a7b1-d0c754f73f6c"> by his wife Hilaria </a> .

His sugar intake was far too high. So he cut out pasta, bread, and other refined carbsdropping 25 pounds and looking better than ever. Kevin Winter - Getty Images

28) Ricky Gervais It wasnt so much about the weight, comedian Ricky Gervais <a href="https://people.com/bodies/how-ricky-gervais-and-girlfriend-jane-fallon-lost-40-lbs/" id="870d9541-9317-3302-aea9-bb5fa91c3299"> told People magazine in 2010 </a> .
