In Search Of A Healthy Gut, One Man Turned To An Extreme DIY Fecal Transplant (theverge.com) 136

Josiah Zayner writes: Arielle Duhaime-Ross at The Verge followed Dr. Josiah Zayner, a former Scientist at NASA turned BioHacker, as he attempted the first ever full-body microbiome transplant. She writes "Over the course of the next four days, Zayner would attempt to eradicate the trillions of microbes that lived on and inside his body -- organisms that helped him digest food, produce vitamins and enzymes, and protected his body from other, more dangerous bacteria. Ruthlessly and methodically, he would try to render himself into a biological blank slate. Then, he would inoculate himself with a friend's microbes -- a procedure he refers to as a 'microbiome transplant.'".

    There are other ways to adjust the bacteria present, such as through diet. Furthermore, eliminating bacteria that ward off other, harmful, microbes seems dangerous. Why would you do this? I suspect this can be filed alongside things like very low calorie intake diets as a way to do some really serious harm to your body.

        Totally different, probiotics usually have assorted bacteria that are usually not associated with a healthy or unhealthy gut. Microbiomes, like those of the gut function as communities meaning you can't just add one or two species and hope everything is better(at least not from what we know at the moment). Using a fresh poop sample increases the chances that not only will a transplant take but also that the beneficial microbes will be there in the appropriate amounts to be beneficial.

        The probiotics can help people but they are far from complete. We don't even know the full composition of the gut microbiome.

        I'm not sure why he pushed it as far as he did, but the procedure he did on his gut is gaining acceptance in spite of the FDA rushing in to put the brakes on progress.

        • If probiotics really contained bacteria that could survive in our gut and make us healthier, we would just need to take one single dose and the company would not make any money on them.

          So instead, I suspect they contain bacteria that may provide some short term benificial effects, but are not really suited for our gut and disappear shortly afterwards. That way, you need to take them repeatedly and keep spending money on them.

          So if you want a healthy gut, probiotics are not the answer.

      That worked for me. A few years ago I bought a $39 yogurt maker from Amazon, and started eating a bowl fresh from the incubator every morning. As my gut bacteria changed, so did my appetite. I no longer craved sugar or other carbs, and started eating more fiber and veggies. I guess the little critters were using some sort of chemical feedback to make me eat a diet more to their liking. I am about 5 pounds lighter, have more energy, and have had no gut problems (diarrhea, constipation, or pain) in years.

In many cases it may be possible to transform an existing gut into another just with fecal matter. We also need to know more about the component bacteria. It is likely possible we could artificially culture a healthy gut biome in an artificial gut. We just need the bacteria and it needs to become tasteless like a powder added to food.

    And cravings and the gut biome need to be thoroughly analyzed. And eating it might not be the ideal to replicate a biome; the digestion in the stomach could kill some bacteria but not others and or alter the concentrations.
