10 Photos of Lee Sung Kyung Revealing Sacrifices as an Actress, Having Stretch Marks Due to Extreme Weight Gain for 'WEIGHTLIFTING FAIRY KIM BOK JOO'

Lee Sung Kyung shared her career journey in the acting world as a guest star on Suga BTS' YouTube content, Suchwita. She revealed the sacrifices she made to embody her role as Kim Bok Joo.

Portraying a weightlifter, Lee Sung Kyung had to gain almost 10 kg compared to her current weight during filming.

She had to undergo this transformation quickly because Lee Sung Kyung only had 15 days after finishing the filming of 'THE DOCTORS'.

The duration to gain that much weight was further reduced because Lee Sung Kyung also had to complete filming for another advertisement project.

Finally, Lee Sung Kyung took an unhealthy shortcut by eating Galbijjim even though she couldn't handle spicy food. Not only did she gain weight, but her face also became swollen in the morning.

Lee Sung Kyung mentioned that she doesn't care about gaining weight, but she's worried about not meeting the expectations for her role.

Furthermore, Lee Sung Kyung took other extreme measures such as eating late at night before sleeping, which eventually had a negative impact on her body. One of them is digestive problems.

The extreme methods that Lee Sung Kyung did also left lasting marks until now. She admitted to still having stretch marks obtained from the drastic transformation of her body.

Nevertheless, Lee Sung Kyung admitted that her sacrifice to transform into Bok Joo was a historic milestone that made her feel like a true actress.

Lee Sung Kyung's sacrifice also paid off as many of her fans still fail to move on from Kim Bok Joo, who left such a deep impression in their hearts until now.
