The following Mark's Daily Apple article was written by Mark Sisson,

Five non-dietary factors that influence your microbiome.

The microorganisms that reside in, on, and around our bodies influence almost every facet of our well-being.

Part of maintaining microbiome health is maintaining homeostasis.

Another is supporting diversity.

Our goal, then, is to improve our microbiological real

estate in the many areas of the body that commensal and symbiotic bacterial like to put down

roots. The gut, mouth, lungs, skin, reproductive organs, and so on. The average primal

enthusiast is well-versed with the role of food

choices and smart supplementation, although research is always uncovering new wrinkles, more on this to come.

I thought I'd give a little attention to some of the other basic practices that can influence

microbial diversity in homeostasis. There are many answers and nuances that I

can cover today, but let's start with some of the fundamentals. Number one, exercising. Over the past

decade, there's been the odd study examining the link between exercise frequency, duration, and type,

and the microbial response to such

in the body. Studies in mice have shown considerable responses to exercise in the lab. A 2016

study placed mice on an obesity-causing diet and six weeks of high-intensity interval training,

otherwise known as HIT.

The mice placed on the HIT program had markedly increased microbial diversity within the distal gut, along with an increased bacteriotease-fermucase ratio.

Perhaps even more importantly, the microbiome of the H hit mice appeared to resist the typical adverse changes

to the gut microbiota that occur with the onset of obesity.
