A controversial new diet that sees devotees swapping food for fluids delivered through a feeding tube is becoming popular among brides-to-be in the US.
The 10-day K-E diet, which costs $1500, sees a tube inserted into the dieter's stomach via the nose, providing fat, protein and water to the body, ABC News reports.
The patient will not eat for 10 days and will need to carry around a shopping bag filled with protein rich fluids, which is linked up to the nasal tube.
The drip delivers 800 calories a day but Dr Oliver Di Pietro, who advocates the extreme weight loss solution, said people on the diet would not feel hungry.
"Within a few hours your hunger and appetite go away completely, so patients are actually not hungry at all for the whole then days," Dr Di Pietro said.
Dr Di Petro said the diet could cause lack of energy, bad breath, constipation and was potentially dangerous for people with kidney issues.
But psychologists have also warned that dropping weight too quickly can be mentally traumatic.
Psychoanalyst Bethany Marshall of Beverly Hills told ABC News it was also not guaranteed those who lost weight on the diet could keep it off.
"If you lose the weight too quickly your mind is not going to be able to catch up with a newer, skinnier you," Dr Marshall said.
Some brides-to-be opt for the diet because they say they don't have time to exercise in the frenzied lead up to the big day.
Jessica Schnaider, 41, from Surfside, Florida said she shed about 5kg in just eight days after going on the diet.
"It was emotionally difficult," she told ABC News.
"And sometimes I had to give excuses to people who were asking are you sick? And I was like, "No, I'm not sick, I'm not dying, I'm fine."'
