Dating site BeautifulPeople.com, where attractive members vote on whether or not applicants are hot enough to join, claims to have rejected 7.5 million people since its launch in 2003.

Applicants who have been turned down are taking extreme measures to change their appearance and measure up, reports The Daily Mail.

Canadian woman Kelly O’Donnell explains how she decided to transform her looks in order to be admitted to the site – completely making over her appearance and even becoming a nutritional consultant.

“After reaching 200lbs (90 kilograms) I knew my life had to change,” she said. “I was tired of feeling run down and sick all the time. So I decided to learn all I could about nutrition and began to exercise. Eight years later, two half marathons and 90lbs slimmer, I truly have left that life behind. I love the results.”

Polish student Aleksandra Pieczek said she changed her life because “I didn’t want to be a nobody.”

“I changed my diet, my lifestyle, I started to be active, following a Mel B fitness program, using my bike, swimming, Zumba," she said.

German man Alexander Siegwardt said “I was rejected by BeautifulPeople.com so many times, so I decided to change my life to boost my confidence. I worked out seven times a week for nine months now and I simply enjoy my transformation as much as the attention and interest from others that I get.”

BeautifulPeople.com managing director Greg Hodge said there are no limits to the number of times someone can apply to the site, adding: “it is not unusual for us to see three, four or sometimes more than 20 attempts to get through our very stringent voting-in process.”

He said there is much people can do to improve their appearance, with things like straightening your teeth, eating less, taking more care with personal grooming or taking up exercise making a big difference – leading to a rise in second time successes this year.

“Many people write us off as a heartless, lookist dating community that exists to alienate the aesthetically disadvantaged. But that’s not true. We want to encourage people to make the best of themselves,” said Mr Hodge.
