What happens when you eat like a Victoria's Secret model for a week?

If you’ve ever tuned in to a Victoria’s Secret fashion show, chances are you’ve wanted to know the secret behind their impossibly long limbs, tiny waists and thighs that don’t meet in the middle.

But, it turns out that being a VS Angel and maintaining the physical image associated with the brand is a seriously gruelling, and damaging task.

In a bid to debunk what people deem as healthy, two YouTubers decided to take on the diet of a pre-show Angel only to be left feeling worn-out, moody and seriously underfed, the Daily Mail reports.

Candace Lowry and Michelle Khare teamed up for a new video where they decided to spend four days eating like one of the famous super models.

Despite citing a dietician consulted by Shape who said, “I wouldn’t recommend this diet to anyone,” the pair decided to go ahead but explained that they wouldn’t be going the whole hog.

Instead, they limited themselves to two ‘normal’ days of eating like a model before moving on to the arduous pre-show liquid only diet for another two days.

Their routine was based on the habits adopted by one of the most prominent and longest-serving Angels, Adriana Lima, who revealed the lengths she went to before an event in an interview with The Telegraph in 2011.

Nine days before the show, Lima claimed that she would drink nothing but protein shakes made with powdered egg and a gallon of water. Then, two days before showtime she would cut back on the water before the 12 hours leading up to the show where she would consume nothing at all.

“No liquids at all so you dry out, sometimes you can lose up to eight pounds just from that,” she said.

For the first day, the YouTubers ate a diet of oatmeal, egg whites and orange slices followed by a ‘boring’ dinner of broccoli, quinoa and chicken breast.

But by the second day, Michelle was already complaining of feeling very ‘tired’ and by third admitted that she was struggling with a terrible mood bought on my practically starving herself with the liquid diet.

“This diet is terrible and I wouldn't wish it on my worst enemies,” Michelle said.

“It's not a healthy way to lose weight and it's strange to me because... no one as a regular person would go through this and these models are supposed to represent the people buying the clothes.”

At the end of the experiment, Michelle insisted that the liquid diet days were nothing more than survival and that it had caused her to have trouble sleeping.
