The microbiome or gut bacteria seem to be an important factor determining whether an individual can become overweight or obese. The new research that concluded that gut bacteria may cause obesity provides more details how this process occurs.
Previous studies have revealed that a diet rich in fiber could change the composition of the gut bacteria making weight loss much easier. However, recent studies conducted by Lund University in Sweden have shown that bacteria may indeed increase the risk for obesity.
Here are the bacteria involved in obesity
According to the last year study in this regard, obesity risks may be increased by three bacteria from the Lachnospiraceae family (Blautia, Dorea, and Ruminococcus) and SHA98. Also, researchers have shown that these bacteria influence our metabolic rate and may cause cardiovascular disorders and Type 2 diabetes.
The study described above was carried out by specialists from the Department of Twin Research And Genetic Epidemiology at King’s College London in the United Kingdom, the Department of Microbiology and Department of Molecular Biology and Genetics at Cornell University and the University of Colorado, and scientists from the Max Planck Institute for Developmental Biology, in Germany.
A recent study shows that metabolites are linked to gut bacteria
The scientists at the Lund University of Sweden examined stool and blood samples of 674 subjects at the MOS (Malmö Offspring Study).
Researchers discovered 19 metabolites that may be connected to the BMI (body-mass index). They concluded that BCAA (branched-chain amino acids) and glutamate are showing the most powerful link with the risks of obesity.
“The differences in BMI were largely explained by the differences in the levels of glutamate and BCAA,” explained Marju Orho-Melander, a professor at the Lund University, in Sweden.
“This indicates that the metabolites and gut bacteria interact, rather than being independent of each other,” he added.
Therefore, gut bacteria may cause obesity.
