Results showed that the combination of probiotics with DI raised microbial diversity, as compared with individual application, of the two butyrate-producing families Ruminococcaceae and Lachnospiraceae. The researchers found strong evidence that the microbiome is linked with specific foods and diets, and that, in turn, its composition is also associated with levels of metabolic biomarkers of disease.

Patients who undergo Rouex-en-Y gastric bypass RYGB experience enhanced metabolism that cannot be explained by caloric restriction and weight loss alone. Comparisons of microbiota from colonic mucosal biopsies and stool samples have shown that there are compositional differences between the mucosa-associated and the luminal fecal microbiota and thus stool analysis might not accurately reflect the gastrointestinal tract. Conserved shifts in the gut microbiota due to gastric bypass reduce host weight and adiposity. Gut microbiome and serum metabolome alterations in obesity and after weight- loss intervention.

Am J Clin And obesity. Improved glucose control and reduced body fat mass in free fatty acid receptor 2-deficient mice fed a high-fat diet. In a study using a mouse model of gastric bypass surgery to characterize changes in the gut microbiota, gastric bypass induced substantial, rapid and sustained changes in the gut microbial communities that were independent of both diet and the weight loss associated with this procedure since mice given a sham procedure and put on a calorie restricted diet had the decreased weight loss but not the change in microbiota. Cell Biosci.

Feeding the Good Bacteria

To further prove the point, the researchers transferred 54 varieties of bacteria from some lean mice to those with the obese-type community of germs and found that the animals that had been destined to become obese developed a healthy weight instead. Beyond Probiotics Many scientists who work on the microbiome think their research will inspire a new generation of tools to treat and prevent obesity. It should be noted that there are dangers associated with fecal microbial transplants since it is not possible to eliminate viral pathogens by filtering and should only be used as a final treatment for human conditions such as recurrent Clostridium difficile infection.
