Yoon Eun Hye has always been self-conscious about her weight. She has said that her frame is so slender that even a few extra ounces can make a difference.

When she appeared on "One Night Of TV Entertainment," she said that her bones were so thin it's easy for her to look as if she gained a lot.

The star of "Coffee Prince," "Princess Hours," "Future's Choice" and "Missing You," currently weighs about 100 pounds. As the youngest member of the girl group VOX, she weighed about 20 pounds more than that, but a rigorous diet and exercise program helped her successfully lose and keep the weight off.
