Actress Moon Chae Won has just opened up about her weight loss routine ahead of her wedding this summer.

On May 28, Moon Chae Won posted a new video to her personal YouTube channel, sharing her dieting secrets. She explained her methods for losing weight for acting roles, and revealed that she's currently dieting to prepare for her upcoming wedding. She also gave a brief sneak peek of her wedding photoshoot, sparking interest from fans.

"It's been a while since I've dieted, so I've lost some of my self-control," Moon Chae Won admitted. "It's hard to hold back in front of food."

However, she explained that the diet would be temporary: "This time, it's just a quick one-week diet for my wedding photoshoot. If it's for a week, it doesn't matter what you eat - it just has to be portioned right, and you can eat anything stress-free. I'll show you how it's done."

Moon Chae Won called herself the 'portion fairy,' and showed viewers that the secret is to eat a fist-sized portion of each food group per meal. She demonstrated with various types of foods, and emphasized the importance of making sure to always eat enough carbs. "You need carbs. Especially for women. If you don't eat enough carbs, it can cause hormone issues. That's what my doctor told me."

She advised eating a fist-sized portion of protein per meal, as well as a palm-sized serving of vegetables. For items like chocolate or butter, Moon Chae Won recommended eating a thumb-sized amount.

She showed how to create a meal using fist-sized portion sizes, and humorously added, "If you have small fists, I can't help you with that." She gave the additional advice of leaving some space in your fist when you measure, without clenching your fist too tight.

Moon Chae Won revealed that the 'fist-sized portion' trick is how she lost weight for her role in 'Flower of Evil.' "In the beginning, I think I lost about 2 to 3 kg (4-6 lbs) from my original weight before we started filming. Even though I lost more weight than Lee Joon Gi, I looked chubby in episodes 1 and 2. So I started dieting again around episode 3. Doing that, my weight dropped to around 45 kg (99 lbs)."

She revealed the unexpected problems caused by her drastic weight loss. "Around episode 10, there didn't seem to be any issues, but I wasn't getting the okay to film. It was weird. I was like, 'What's wrong?' and they kept resetting the lights. I thought it was strange, and suddenly the director called me to the back and said I should stop losing weight. My cheeks looked too hollow so they were trying to fill them in with the lighting. I had lost that much weight."

Moon Chae Won completed the video by showing some of her meals and workout routine as she prepared for her wedding photoshoot. She also revealed a sneak peek of the final photoshoot at the end, raising fans' anticipation for the fully-revealed wedding photoshoot.
