Let's say you're a bride and you need to lose 10 pounds to fit in to your wedding dress in June – what are you going to do? If you're Jessica Schnaider, the answer is, go on a new diet that involves sticking a feeding tube up your nose that will drip protein and fat mixed with water down in to your stomach, with zero carbs and a mere 800 calories a day.

"I don't have all of the time on the planet just to focus an hour and a half a day to exercise so I came to the doctor, I saw the diet, and I said, 'You know what? Why not? Let me try it. So I decided to go ahead and give it a shot," Ms. Schnaider told Good Morning America. Going on the K-E diet wasn't easy, though, as you could imagine. "It was emotionally difficult, the 10 days of not eating," Ms. Schnaider said. "And I was like, 'No, I'm not sick, I'm not dying, I'm fine.'"

Fine? Well, not entirely.

"I was tired," Ms. Schnaider went on to explain. "I didn't feel like exercising. The doctor told me that if you can complement [the diet]with walking for half an hour on the beach, that would be great, but I didn't feel like doing that. I'm a very energetic person, but those days I was a little tired."

Dr. Oliver Di Pietro, of Bay Harbor Islands, Fla., said the K-E diet is a "hunger-free, effective way of dieting. Within a few hours, your hunger and appetite go away completely, so patients are actually not hungry at all for the whole 10 days. That's what is so amazing about this diet."

Although you have to keep a feeding tube up your nose for 10 days straight, it comes with the promise of losing up to 20 pounds in that time period.

While most health professionals will tell you it is safe to lose up to 3 pounds a week, in Dr. Di Pietro's view, the downsides of far exceeding that are quite minimal.

"The main side effects are bad breath. There is some constipation because there is no fibre in the food," he said.

The K-E diet might be new to the U.S., but it has been used in Europe "for years," according to Good Morning America.

Just how much does it cost?

Dr. Di Pietro charges $1,500 (U.S.) for the 10-day plan. You know what else you could buy with that money: a gym membership and healthy food that you could consume in moderation.

Would you ever go on a crash diet? What about one that required a feeding tube?
