Controversial K-E diet has gained critics who say that it induces a form of starvation.

An extreme dieting trend is catching on in the United States, that is neither pretty nor comfortable.

The K-E diet involves a person being fed through a tube in their nose, receiving a mix of protiens and fats, but no carbohydrates.

Patients are fed continuously through a feeding tube and have to carry a pump 24/7 for the full ten days of the diet. The results are quick, with most people losing just under 1kg a day.

But the diet has also gained critics who say that it induces a form of starvation.
