Celebrity diet routines and workout rank among the most searched health topics online. While many look for fitness inspiration, others simply wonder if there is truth behind the hype, wanting to know if these routines are accurate or possible in real life.
We checked five top routines: Sydney Sweeney, Sabrina Carpenter, Lisa, Han So Hee, and Winter. By debunking pure internet myths, we see if these viral claims live up to the facts and whether copying any part is safe or practical.
Sydney Sweeney
Sydney Sweeney’s workout for the boxing biopic Christy drew attention because it reflects the demanding actor training regimens used to prepare for physically intense roles.
She confirmed the grueling schedule herself in her W Magazine cover story: three and a half months of training, weights every morning, two hours of kickboxing at midday, weights again at night. She packed on 30 to 35 pounds on pizza, Chick-fil-A, and protein shakes. Her trainer, Grant Roberts, later explained the strategy to Yahoo, the goal was never a chiseled look. It was about power, meaning bigger meals once her protein targets were hit.
Verdict: Mostly Fact. This diet only works for building muscle if you match the extreme lifestyle behind it. High protein was the main priority, paired with intense training 2 to 3 times a day for months. If you cut back on the workouts or miss your protein goals, this meal plan won’t produce the same results.

Sabrina Carpenter
There are several online theories about Sabrina Carpenter’s workout routine. People believe she must be running some kind of disciplined performer’s regimen behind the scenes, hours of rehearsal dancing as her main cardio, plus regular biking and yoga to round it out.
Her actual answer, given directly to Marie Claire, is much smaller than that. She describes her exercise as casual, not a daily habit. At most, once or twice a week she does something more structured, like a class or a workout at home. Pilates comes up specifically, usually with friends, because working out socially makes it not feel like exercise to her.
Verdict: Mostly Myth. You can achieve a strong, lean, and toned physique by doing Pilates once or twice a week. However, matching Sabrina Carpenter’s exact look is impossible through workouts alone, as her appearance is heavily shaped by her 5’0″ genetics and the massive calorie burn of touring and performing.
Lisa
Asked directly by W Korea whether she exercises for her health, Lisa said she mostly doesn’t, since BLACKPINK holds a lot of concerts. The stage happens to double as cardio, which is different from a chosen regimen. The Pilates and boxing clips that circulate trace back to scattered behind-the-scenes footage, not a routine she’s described as fixed.
On food, she told Youth With You 3 trainees, that a full stomach matters before intense practice, since skipping meals leaves you without energy. While there is no specific breakdown of BLACKPINK Lisa’s diet, she is often seen eating pizza, ramen, and soup in some of her vlogs.
Verdict: Myth. Lisa burns an immense amount of calories through hours of intense, professional dance rehearsals and performances, far exceeding what a typical person burns with standard weekly workouts. A typical person with a sedentary job eating the same amount would gain weight, as normal workouts can’t match her high energy output.

Han So Hee Diet
During the filming of The World of the Married, Han So Hee said in interviews at the time, she skipped breakfast, ate a small portion of chicken breast at night, and cut her water intake to avoid bloating. Fans also noticed that her weight has swung noticeably between projects too.
When a fan asked how to get as thin as her, she said plainly not to try, explaining that her weight is a job requirement tied to how she has to look on camera, not a personal standard, and that thin alone was never the same thing as beautiful.
Verdict: Pure myth. If an everyday person tries this diet, they will not get healthy or lasting results. Skipping meals and cutting water is extreme starvation and dehydration, not a realistic way to manage your weight. It is a temporary trick. Even Han So Hee says it is not a plan anyone should copy.
aespa’s Winter
aespa’s lead vocalist Winter has addressed her frame herself, saying in a livestream, that she doesn’t gain weight even when she eats a lot, and framing her workouts as something she does for health, not for dieting. Her own account of one week includes four gym sessions, three to four separate Pilates sessions, dance practice on top of that, and walks because she genuinely enjoys them.
Verdict: Fact. Focusing on strength and health instead of starvation is a possible functional approach that works. If a normal person consistently mixes gym sessions, Pilates, and daily walking while eating full meals, they will build real fitness and energy. Her high movement level is a legitimate strategy that produces actual physical results.

Are Celebrity Diet Routines Safe to Copy?
In most cases, no.
Most celebrity workout routines are designed for performers with professional support, not for everyday lifestyles. They overlook trainers, nutritionists, and job deadlines like shoots or performances. That’s usually how celebrities stay in shape.
Many viral posts also spread dangerous diet myths that contribute to toxic diet culture, making extreme habits seem normal when they are not. It can also mean rapid loss that does not last.
The takeaway is simple.There are no hidden celebrity fitness secrets. The most effective celebrity workouts focus on consistency, recovery, and long-term health: eat enough to fuel your body, stay active in ways you enjoy, and leave room for your favorite treats. While Hollywood fitness trends and idol workout routines can be inspiring, be cautious of what is actually realistic.
