Your gut microbiome also exerts a powerful influence on your weight. Gut microbes known as Firmicutes have been detected in higher numbers in obese individuals, who also may have 90 percent less of a bacteria called bacteroidetes than lean people.7 In a Medscape interview8 published in April, 2015, Dr Martin Blaser, who heads up the Human Microbiome Center at New York University, discussed the links between your gut microbiome, obesity, and chronic disease.
As noted by Dr. Blaser:
"The basic idea is that the microbiome is ancient. The organisms that we carry are not random; they have been selected over eons of evolution. They are important for our physiology, and there is a lot of evidence for that. My big point is that they are changing. As a result of the change, there are health consequences ...
I believe that there is a general paradigm that we are losing important organisms early in life, and that is fueling some of the diseases that are epidemic today."
