PHILADELPHIA (CBS) – A diet trend for quick weight loss has local experts worried.

Want to lose a quick 20 pounds? Brides to be are trying the K-E diet, where you stick a feeding tube up your nose and ingest just a few hundred calories a day of liquid protein and fat. Jodi Krumholz, Director of Nutrition at the Renfrew Center, an eating disorder facility in Northeast Philadelphia, says it’s a dangerous practice.

“Even though they might just do this one time for the wedding, I think there can be addictive qualities to diets, and I think that someone might continue to do something like this. And it could put them in a really dangerous low weight place,” Krumholz explains.

Plus, the diet works by putting the body into ketosis, where a person burns fat instead of sugars, and Krumholz says that harms your health by causing kidney and liver problems, along with dizziness and vomiting.
