Newswise — What should be a fairy-tale day — a woman’s wedding — could turn into a nightmare for a bride-to-be who goes on a new feeding-tube diet to lose 20 pounds fast, says a Baylor University professor and a former chair of a public policy committee for the American Dietetic Association.

The diet of about 800 calories a day for 10 days has a potential to be even more harmful and less long-lasting than the so-called liquid “starvation diets,” of fewer than 1,000 calories a day — far below standard recommended weight-loss diets, said Suzy Weems, Ph.D., chair of Baylor University’s family and consumer sciences and a consulting dietitian who has worked for hospitals and extended-care facilities. Most recommended diets call for a combination of exercise and eating that create a 500-calorie deficit from normal needs.

Some doctors — over the vigorous protests of others — have promoted the diet as a quick, hunger-free way to shed pounds by delivering protein, fat and water through a nasal feeding tube.

“It seems very extreme because of its potential for infections and irritation,” Weems said. “It seems to be illogical to do this for one fairy-tale day when most brides have plenty of time before their weddings to lose weight in a healthy way. The long-term solution to maintain a good weight is eat right and exercise.”

What’s more, healthier diets provide “more energy for intimacy,” she said.

Reports about the crash diet have appeared on ABC News and other major news outlets.
