A4 waist challenge: The thinner, the better?

Editor's note: The "A4 waist challenge" where women take photos with an A4-sized paper placed in front of their midriffs has swept the Internet. Many Internet users have posted photographs online to show off their trimmed waistlines, sparking heated discussions about the beauty standard. Forum readers share their opinions.

Such body standards are ridiculous as not everyone has the same body type, not everyone is going to be able to pass the A4 challenge. Some women have wider set hips, some have bigger bones; there are a multitude of factors that mean you may not be able to pass this challenge...and who cares? This is not healthy in the slightest; it is not a healthy standard to set your lifestyle by. Not eating to achieve this isn't for your own health; don't ever delude yourself into thinking otherwise. If you are starving yourself, you are putting yourself through ridiculous amounts of pain and pressure for other people.
