  1. I contribute my microbes to uBiome. I would love to participate in this discussion.

    I can’t.

    Because I have no idea what the podcast is all about.

    Why?

    I am deaf hence the podcast is inaccessible.

    As you promised a transcript and I have yet see a transcript.

  2. Tim, at a certain point, Jonathan mentions about the study that we’d be 50% microbial cells and 50% normal smashing the myth of 90% – 10%. could you please point out to the study?

    I tried finding it, but I got no luck. Thanks!

I’d really like a outline tree with a summary (pref. with hyperlinks that refer to the specific piece in the podcast) so I don’t have to skim the audio and can actually see what the actions are. I like to start with the decisions I might want to take and get information from there, not the other way around.

    So far, it’s pretty clear that the bacteria in our gastrointestinal tract have a profound influence on our cardiovascular system, chronic inflammation, body composition,and even depression.

    Startling to realize how powerful are these microscopic critters.

  9. HI Tim, I was bit by Lyme in 2007 after traveling to Africa, Ecuador and China, I came back to the US for my friend’s wedding in PA and I was bit by this life altering disease. Amazing how I didn’t get anything until I came back to US soil. Just awesome!.. (sarcasm). I’d love to know what diet & treatments you have found that works for you. My brain fog has gotten the best of me lately.

    Thanks

    • Hey Tim and Lauren,

      I am also a Lyme patient and have done extensive research on the subject because of the extreme brain fog. As far as diet goes the best thing I have found is to go with a low carb high health fat diet such as the Bulletproof, Paleo, or Ketogenic diet (avoiding sugar, gluten, corn and processed foods). The purpose of these diets is to reduce inflammation caused by the Lyme that is more than likely attributing to your brain fog. With this i really found the key to the diet was completely eliminating sugars to be able to kill the Candida in my gut which was not allowing my medications (both natural and antibiotics) to work as well as they could. Although the antibiotics obviously work in killing off Lyme I think that if I were to go back with the knowledge I have now I would not have taken that path due to the deteriorating effects they have on your gut and your micro biome.

      Alternative natural paths could include using different oils such as Samento oil or Cats Claw which both help to lift brain fog. Also I’ve began to take an all natural Colostrum supplement which has been shown to help work almost as an antibiotic in killing of Lyme while also rebuilding your gut at the same time (also gives you great energy). On top of the treatments I think that you MUST supplement with a good multivitamin and high doses of Vitamin D, Magnesium, and CoQ10. Thorne FX is by far the best brand out there, and you will not find better quality on the market.

      After you have nutrition and supplementation taken care of its time to use some of the “woo woo methods”. Methods such as meditation, tapping, and quigong are great for opening up the mind and the body to staying positive and de-stressing. Other things that may work but are a little more on the pricey side are Rife Machines, and Ozone therapy. Rife uses certain vibration frequencies to match the frequency of the Lyme to kill it. I am not as knowledgable on on Ozone therapy but it seems to be very effective in killing infectious and autoimmune diseases.

      The best thing you can do for yourself is find a Lyme literate doctor, ask questions, and keep doing research for your self because even a lot of Lyme docs are not up on all the best forms of treatment. Lyme effects each person differently and we need to all learn how to stay positive in fighting this disease because from personal experience I know that it is possible to beat!

      Good Luck in your pursuit of health!

  10. Hi Tim
    During the interview you commented on donating sperm and getting past your “best before date” (I’m paraphrasing). Recently…within the last year…
    I was reading or listening to something on stem cell research and it said that the only two cells that don’t age are cancer cells and sperm cells. I just turn 47 and gave up on having kids long ago. After hearing that I am considering having kids again. I would be interested hearing any further information regarding this and the risks (to the child) of having kids after a certain age for men. Thanks! Really enjoy your stuff.

    Best medical / biological test:

    1. Has to be the wonderful (and frightening) tests available that let us know our twin embryos were healthy (healthy = free from the diseases they were screened for); and that we were having a boy and a girl. JACKPOT! : )
    (They are 5 now and life is full…)
    2. I was surprised and grateful to learn back in 2006 that a blood test could help diagnosis and catch potentially serious medical problems.
    I suddenly felt sicker than ever and almost immobilized one night in 2006. The next day I went in and blood tests were ordered. I didn’t have the flu as suspected, I had pancreatitus. This led to more tests to find the cause and turns out I had gall stones. I got treatment and became well again. (Thankfully, this was all taken care of before becomming pregnant with the twins. ) I learned a lot about my whole digestive system in the process.

  15. In regards to the honey before bed. Two other substances that would be interesting to see work, IF someone has access to them. Or if someone knows where to get access to them let me know.

    I wonder if Peter Attia’s synthetic keytones would perform similarly to honey or not? Assuming one can choke it down.

    The other would be if C7 Oil (Triheptanoin)?

    Mainly to see if it is actually glucose/fructose involved or the fact that some sort of high performance energy source is supplied right before bed.

  16. In regards to the honey before bed… I’m curious if it is the glucose/fructose specifically or other substances in the honey or if it is the energy it supplies to the brain. If it is the energy it supplies to the brain during sleep, then it is possible the following two substances could also work.

    1. Peter Attia’s synthetic keytones, assuming one can choke them down.
    2. C7 Oil (Triheptanoin) – I’m assuming this is easier for the body to use as an energy source than regular MCT oil.

    I don’t have access to these, but if someone does it would be nice to see if it does work. Then we’d know it was the supplementation of energy right before bed and not some other substance in the honey.

  18. Oh, and the most interesting thing I’ve learned in a medical/bio test was that I needed to put together a DIY FMT capsule protocol to cure a decade of annoying mutherfucking illnesses!

    Fact is, knowing what bacteria are in your gut and how your small intestine works (or doesn’t) will change your life. There’s lots of hope out there for many inflammatory and neurological illness sufferers but, unfortunately, most of us find it impossible to even maintain a suitable diet to ‘feed’ our good bacteria.

    As for tests: uBiome is a good start. But it drops you into the proverbial rabbit hole … which is where everyone gets lost.

    Also… Got auto-immune issues? Then eating paleo isn’t going to be your friend.

The point Jonathan made about spending the money on experiments reminded me of your question to Ed Cooke about if he’d rather have one guy spending an incredible sum, or many others spending relatively large sums.

In that case you are dependent on a single person or group recognizing them and funding it.

  20. You say you are in a less productive period, yeah but you are producing amazing podcasts.

    This topic interests me because if one is paying attention to one’s health then their digestive system is important. In 1979 I started experimenting with eating a lot of fiber (the so called “save your life diet”…if you didn’t blast a bran storm diet really). High fiber diets are healthy, but too much bran is not good for the colon. The amount of water consumed can affect stools significantly.

    My wife is an expert at propagating pathogenic bacteria. It is true that there are no ideal probiotics. My wife says that one of survivable ones is Dr. Ohhira’s. It seems to work well for me. Eating raw foods like a locally grown apple is a good source of probiotics. If you live in an urban area you are living in a sea of enteric bacteria (due to the 1000s of gallons flowing in sewers and people and pets crapping everywhere) so there is no need for probiotics. More likely in urban areas people can get incompatible or strains of E. Coli. I am fortunate to beach it in Mexico every year. I get something every year after a week. I take pep-to Bismol which kills gut E. Coli. When I get home the normal flora comes back.

  23. Hey Tim! Happy New Year mate. A quick note if you’ve got a minute: I want to start moving on my long-term goal of raising the funds to build a school in Vietnam.

    My business is repairing Guitars and Amplifiers and building electric and acoustic guitars in Melbourne, Australia.

    I could use clarification from you as to what might prove most effective:
    I plan to a) use everyday customer flow to generate funds based on a percentage of their normal fee – average spend per customer per visit = $180
    b) when i build a guitar, ask the customer to donate a percentage of the guitar’s costs AND offer to match that donation myself – electric is $3300, acoustic is $5000
    c) every six months or so build an artistic guitar to auction online, all proceeds going to this cause. – purposefully lavish and unique with a starting bid of $6000

    Do you think the a) option should be optional or compulsory?

    How do people respond to what is effectively a tax on their services? As in, what is their threshold? Should I be asking 5% or 15%?

    I’m aware you have spent time in Australia and so have a flavour for the culture. As a reference point Australians spend more on alternative medicine than any other developed nation and in the last economic downturn (approximately GFC 6 years ago) the average spend on health and fitness increased. From a marketing perspective I need to KISS this and could really use your advice as to what experience has shown works best.

    My 6 year old son is about to start Primary school and is very excited. Having had a mostly free tertiary education to Masters level I am aware of its advantages in a global workplace and I would like to offer that opportunity to others born in less fortunate circumstances.

    Many thanks in advance to everyone out there.

I just stumbled upon an article today (http://www.freeenterprise.com/story/the-key-to-a-stunning-medical-breakthrough-your-poop/) about the very interesting and inspiring not-for-profit organization, OpenBiome (www.openbiome.org). The story behind this organization provides a GREAT perspective on the importance of the microbiome. This article is a great complimentary read upon listening to the podcast, and in fact makes me want to listen to the podcast again! (sidenote: also shed light on the importance of the content of our diet, especially as it relates to our food industry, and the poor government regulation of the food industry. More particularly, as it relates to the microbiome and C. difficile, the fact that industrialized animal treatment is reliant on antibiotics, and these antibiotics are passed on to us upon our consumption.)

    To learn more about the issue regarding our industrialized food industry, farmer Joel Salatin has a wealth of information on the issue, which is well extracted on episode #479 of The Joe Rogan Experience podcast (http://vimeo.com/90697297).

  33. Tim,

    I’ve been reading a few things about the microbiome on the one hand and ketogenic diets on the other that have raised an apparent inconsistency to which I haven’t yet been able find a satisfying answer. Hi fat diets are, thus far, said to promote firmicute growth in the gut. And a higher ratio of firmicute to bacteriodete in the gut is linked to obesity (while a lower ratio is linked to leanness). Nevertheless, ketogenic diet promotes leanness. What gives? There appears to be an article in Nature from January 2014 that goes into this, but rather than spend the 10 bucks to order it (and I don’t know how long to read it) I’m being lazy and asking you instead. Do you know how this is reconciled?

    Many thanks, and keep up the good work.

    • I’ve been in nutritional ketosis since August 2013, and I look with interest at studies that purport to find problems with high fat diets. The answer often is in the types of fats. Many of the animal studies, including at least one that found an increase in firmicutes with a “high fat” diet, involve a standard lab “rat chow” that is mostly high omega-6 processed oils. Some of the human studies involved diets that were both high fat and high carb. Typically, when you review the study methods, you’ll find the supposedly problematic “high fat” diets were not akin to a well formulated ketogenic diet.
