I found this short article on Korean actress Yoon Eun Hye. The article was uploaded by "hotshotlover30" on soompi forum and here is what the article says.
On February 22, photos of Yoon Eun Hye comparing her present figure to her past have been attracting netizens’ attentions. Titled “Yoon Eun Hye. Results from Her Strenuous Dieting,” the photo on the left is from an old advertisement and displays Yoon Eun Hye’s chubbier past. The photo on the right is from a more recent period, and she flaunts her slim waist, exposing her midriffs. Many of the netizens responded that two photos side by side looked like before-and-after shots in a plastic surgery clinic.
Those who’ve seen the photos commented, “People do look a lot better once they diet,” “Her arms on the left are the size of her thighs on the right,” “While her body size is different, she still has the same charming smile,” and more.
