Meet Mark

Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...

Research of the Week

Topical animal collagen — in this instance, from tilapia skin — quickens wound healing.

Primary prevention risk calculators are overestimating the chance of heart attacks by up to 154% in men and 67% in women. Yup, the very same risk assessments telling us we’ll all die if we don’t start statins immediately.

A key ketone metabolite blocks the inflammatory cascade triggered by a specific set of genes.

Comment of the Week

There is apparently some small risk of getting variant Creutzfeldt-Jakob disease (essentially mad cow disease in humans) from elk. The disease agent is a prion, which is resistant to high temperatures, and so the brains, spinal cord, and some other parts shouldn’t even be handled, let alone eaten, in areas where the wild elk population is known to have the disease.

http://www.cdc.gov/ncidod/dvrd/cwd/

“Hunters who harvest deer or elk from known CWD-positive areas may wish to consider having the animal tested for CWD before consuming the meat (information about testing is available from most state wildlife agencies). Persons involved in field-dressing carcasses should wear gloves, bone-out the meat from the animal, and minimize handling of the brain and spinal cord tissues.”

Risk is small, but still … google “CWD hunters” for more than you ever wanted to know.

– Thanks for the warning, reader Anne and others.

  1. “For every hour later of [artificial light exposure] in the day, there was a 1.28 unit increase in BMI….”

    ^That article just reinforced my desire to get to bed EARLY again. Anytime I’m up past 9 p.m. I’m not doing anything productive…

    1. All my friends want to disown me since I started to go to bed early… on the weekends. I was already in bed at 9:30 on weekdays, now I have begun to get very close to that on weekends, it works sooooo much better. They all say they want to get the most of their weekend. It’s like they can’t capitulate to the idea that getting up earlier still gives you the same amount of time. It’s called math… use it. Plus, hello? SUNLIGHT! I need new friends.

      1. Dude, I had good friends leave me because I didn’t drink as often and respected my circadian rhythm, always going to sleep by 11… After a year or 2 of it, I kind of decides it’s not worth it during college and switched to a more biphasic sleeping pattern, but i think I feel more tired during the first portion of my day and I’m not the best at naps so sometimes I don’t get my day sleep in
        I would just shift my rhythm forward if I didn’t have to train at 0550

  2. Okay, can someone put the ketone study into English, please.

    About all I understood was “Our findings suggest that the anti-inflammatory effects of caloric restriction or ketogenic diets may be linked to BHB-mediated inhibition of the NLRP3 inflammasome.”

    Googling around produced more science-speak and little illumination.

    Suggestions for a decent on-line biochem course would also be welcomed.

    1. Researchers looked at five of the many inflammatory pathways in mice and found that either a ketogenic diet or exogenous beta-hydroxybutyrate directly blocks one of the five (starvation in general reduces inflammation through unknown or not entirely known mechanisms). Since the pathway in question is associated with a couple of rare genetic diseases in humans, it’s possible that a ketogenic diet or a BHB analog drug could be used to slow the progress of the damage due to these mutations. At least that’s my stab at translation.

      Biochemistry is a pretty vast subject with a lot of highly specialized sub fields. This paper is at the intersection of immunology and biochem.

    2. calcampus offers classes online that you can sign up for. They are not a university or anything so registration is easy. Also, some colleges will accept their courses as credit in case you decide to become a biochem major later in life 🙂

  3. So if we rub some Tilapia skin on our wrinkled faces would that “heal” our wrinkles? Hmmmm, I’ll stick with coconut oil for now, smells better and has been working great so far, still have the wrinkles tho. 😛

  4. Regarding your comment of the week:

    My friend died from Creutzfeldt-Jakob disease.

    As far as anyone knows, he didn’t eat deer or elk or any other wild animals. He was a chronic cardio enthusiast (running) and he bought into the low-fat eating scam.

    We were shocked when the diagnosis was made because it’s usually blamed on eating diseased venison.

  5. Nice job the 1st grade teacher did by giving his students stand-up desks.

  6. Great article on BHB and ketones. This seems to be why resistant starch/indigestible fiber is necessary for a healthy gut biome. Sugar and refined grains may not be inflammatory on their own but perhaps they are not processed into BHB by intestinal flora? I understand grass fed butter is a good detary source of BHB. As a former(thanks Mark) gout sufferer, I have a hunch that nurturing a gut biome that produces BHB may be the solution to a plethora of inflammatory disorders. P.S. I found this Delitia buffalo butter from Italy. It’s as white as lard and tastes like pure CLA. Does anyone else have experience with this? My family does not like it so it has to be good.

  7. Now I feel better about all the times I didn’t finish my course of antibiotics

  8. A C.O.W. regarding mad cow. Maybe I’m a bit reckless but I wouldn’t be worried. Sometimes I don’t even cook all my ground beef and enjoy some raw (usually depending on how hungry / how much of a red meat craving I have and if I’m baking the tube from frozen) and I’ve eaten raw chicken, out of curiosity and to be able to say to myself that I did.
    I had terrible food poisoning twice (quite a while before primal) but I don’t expect to ever get it again. I don’t know much about prions though – I think I might have first learned of them in a Micheal Chrichton book.

  9. Antibiotics. I’m not sure the article suggesting antibiotics be stopped once the patient feels better is accurately portraying the journal article. The original article by Gwendolyn L Gilbert states: ‘In practice the optimal duration of therapy depends on clinical syndrome, the causative organism, whether source control is possible and the patient’s response to therapy.’ The author suggests that antibiotics are often prescribed for longer than necessary, but it’s not as simple as ‘take this until you feel better’.
