Aerobic Exercise and the Health of Your Microbiome

I’ve previously blogged about some exciting research that discovered that the higher your level of physical fitness, the greater the diversity of the bacteria in your gut. The meaning of this? That improved fitness correlates with a more healthy-looking bacterial array in the gut.

Now the more interesting question: if one was to begin a new exercise regimen, would s/he see a change, or improvement, in the diversity of bacteria in the gut. This would be an interventionist trial and, thankfully, there’s a brand new one we can review. Let’s dive in.

      Oh, puuleeeze!! Personal judgments, based on personal preferences, might be personally ‘fun’, but most of us here are interested in FACTUAL INFORMATION.


        For me the most inportant are the infos for our health and not the companys were to buy.

          I live in South Africa and cannot benefit from those recommendations but, having read Dr Perlmutter’s books, I recognise that he is trying to help us get products that will improve and maintain our health. Thank you, Dr Perlmutter.

      interesting that you pick a podcast where Dr. Perlmutter is not “selling” anything except the results of a very interesting study. As a matter of fact, Dr. Perlmutter’s BUSINESS involves informing all of us with helpful, healthful information. If you think this dismisses Dr. P. somehow, then just go troll/lurk somewhere else. Dr. P deserves to be financially benefited from all his efforts, just like anyone else.

    It would be interesting to see, if the obese subjects continued exercising and became leaner, at what point (how lean?) the beneficial changes to the microbiome started.
