Obesity May Be Linked to Microorganisms Living in the Gut

How much a person eats may be only one of many factors that determines weight gain. A recent Cedars-Sinai study suggests that a breath test profile of microorganisms inhabiting the gut may be able to tell doctors how susceptible a person is to developing obesity. The study, published online in the Journal of Clinical Endocrinology & Metabolism, shows that people whose breath has high concentrations of both hydrogen and methane gasses are more likely to have a higher body mass index and higher percentage of body fat. http://www.todaysdietitian.com/news/032713_news.shtml
