I'll bet people who go on this diet gain their weight back shortly after they pull the tube out of their nose.
The K-E diet, which boasts promises of shedding 20 pounds in 10 days, is an increasingly popular alternative to ordinary calorie-counting programs. The program has dieters inserting a feeding tube into their nose that runs to the stomach. They're fed a constant slow drip of protein and fat, mixed with water, which contains zero carbohydrates and totals 800 calories a day. Body fat is burned off through a process called ketosis, which leaves muscle intact, Dr. Oliver Di Pietro of Bay Harbor Islands, Fla., said.
