In Britain, people are dying to be thin -- literally -- and one company is pulling in a profit of about $30 million because of it, according to this article from the Daily Mail.

A popular diet program in the UK, called LighterLife, is wildly successful these days, but it's costing some people their health -- and their lives. The program advocates an extreme calorie deficiency -- participants consume shakes that give them a total daily caloric intake of only 500 calories, and they end up losing weight at an alarming rate. LighterLife claims it's all perfectly fine because the body doesn't need those excess calories, adding that this type of starvation has been used healthfully for over 30 years. Yeah, right.

But now, some people are speaking out about the side effects of this diet. One former participant claims her vision is now permanently blurred and she suffers from ongoing memory loss; another, a dentist, says the lack of calories ruined his wife's teeth; another claims it led her to become anorexic. Other side effects include hair loss, menstrual disruptions and constipation. And if that's not frightening enough for you, consider this: One 25-year-old participant died from heart troubles believed to have been caused by the diet. Click here for some more horror stories.

Unless you live under a rock, you have to know that consuming only 500 calories is bad for you. Even so, I'm honestly not surprised that people are lining up for this diet despite the health warnings, young women will do anything to be thin. What surprises me is that vanity takes a priority over health so often. What good is looking great if you aren't healthy enough to enjoy it?
