As one can imagine, maintaining appearances is one of the most challenging parts of idol life.

KARA member recently Gyuri revealed the pressures of following a strict diet and exercise routine on MBC's Quiz to Change the World 'Expert vs. Idol' special.

Gyuri also explained that she feels stressed being compared to her group mates "Out of the members, Goo Hara and Han Seung Yeon have such skinny body builds, so just being in between them is stressful," she explained. "I've tried out various diet methods."

Those methods were not always healthy either.  Gyuri explained she suffered a lot to maintain her figure. "After working so hard to lose weight and completing an important filming, I found myself seeking out delicious food due to stress," she said.  "I would binge eat, but then I would start exercising again right away out of guilt. And that caused [the food] in my stomach to start coming up, which eventually made me throw up. This repetitive cycle caused me to have acid reflux."

Aware of the dangers extreme dieting can have on her health, Gyuri also warned fans about unsafe diet saying explained, "I did this kind of diet in the past, but I don't do it anymore. Now I do a more sensible diet." She also warned fans not to engage in any unhealthy eating habits and to maintain their figures with a well-balanced diet.
