Can Probiotics change our gut microbiome and effect weight loss? The answer is YES!

Clinical research has demonstrated that having the right gut bacteria can help improve our gut, cardiovascular, immune, and regarding weight control, our metabolic health.

However, numerous animal and human studies looking at the effect of the gut microbiota have shown that maintaining a healthy weight is more complicated than calories consumed = calories burned.

For example, a study at the University of Marseille Medical School showed that gut bacteria of mice fed a high fat diet were different than the gut bacteria of mice fed a normal diet. In particular, when the scientists analyzed the gut microbiota (bacteria species and population), they found a clear difference between the obese mice and the normal mice.  The obese mice had more of a bacteria type called Firmicutes and the normal mice had more of a bacteria called Bacteroidetes. 

The results of the French study were mirrored in a human study at the Center for Genome Sciences, Washington University in St. Louis. At Washington University, scientists showed that obese participants on a calorie-restricted diet had an increase in the proportion of Bacteroidetes. Over a 12 month period, the study participants also showed Bacteroidetes results that correlated with weight loss.

The exact mechanisms of how gut bacteria effect body weight remains a mystery.  However, we do know that gut microbiota plays a critical role in host metabolism. Our “good” gut bacteria help prevent the growth of pathogenic bacteria that can lead to inflammation.  Gut inflammation can damage our intestinal lining, which can lead to a reduction in our ability absorb nutrients and excrete waste. In addition, other recent clinical research has demonstrated that having the “right” gut bacteria can help to maintain a healthy weight, and avoid obesity related health issues. 

Currently, there are no commercially available forms of Bacteroidetes (the gut bacteria associated weight loss).  But, there is a growing body of evidence that shows taking probiotic supplements can help reverse the weight gain and obesity associated with an imbalance of “good” and “bad” gut bacteria.

Overall, the data suggests that there is a real connection between having the right gut bacteria and maintaining a healthy weight.  However, we still have a long way to go in understanding the exact mechanism of action. While we wait for answers , get started with a healthy lifestyle with a fiber rich, low processed carb diet, consistent exercise, and a dose of SuperBio Probiotic every morning!
