"New research suggests the mix of microbes in our guts can either help — or hinder — weight-loss efforts.

"We started with the premise that people have different microbial make-ups, and this could influence how well they do with dieting," explains Purna Kashyap, a gastroenterologist at the Mayo Clinic in Rochester, Minn.

As part of the study, Kashyap and his collaborators tracked the progress of people who were enrolled in a lifestyle-intervention program for weight loss. The participants were advised to follow a low-calorie diet, and they were tracked closely for about three months.

"We found that people who lost at least 5 percent of their body weight had a different gut bacteria as compared to those who did not lose 5 percent of their body weight," Kashyap explains. Their findings are published in the journal Mayo Clinic Proceedings."

"The successful dieters had an increased abundance of a bacteria called Phascolarctobacterium, whereas another bacteria, Dialister, was associated with a failure to lose the weight. And, Kashyap says it's likely that there are other types of bacteria that might influence dieting as well." 

Bottom line: the bacteria eat what else can't

"Probiotics that are currently on the market would not be effective. The idea is to develop a new product that includes the specific types of bacteria linked to successful dieting.

But it's not so simple to manipulate the mix of microbes in our guts. Identifying the organism — or organisms — that are thought to be beneficial is just the first step."

"Four in ten people aged between 18 and 24 have tried a ‘clean eating’ diet, according to an NOS survey of 2,000 adults.

The regimes usually involve avoiding processed foods and eating raw, unrefined produce, and often prohibit eating dairy, gluten and sugar.

More than a fifth of those in the same age group said they had significantly dropped their intake of milk and cheese.

But Vegan groups have said cutting out dairy does not necessarily pose a health risk, because essential nutrients such as calcium “can be easily obtained on a vegan diet”.

Susan Lanham-New, a nutrition professor and clinical advisor to the NOS, said young adults needed to make sure they were receiving nutrients from all major food groups.

“Diet in early adulthood is so important because by the time we get into our late twenties it is too late to reverse the damage caused by poor diet and nutrient deficiencies and the opportunity to build strong bones has passed,” she said.""
