Kurt Harris coming on the podcast – submit your questions!


Published on

I’m happy to announce that the illustrious Kurt Harris of PaleoNu will be joining us on Episode 6 of The Healthy Skeptic Podcast. We’ll be discussing his recent series on macronutrients, the role of meditation practice in helping us to face “unsolvable problems”, orthorexia and more.

We’ll also take some questions from you, so make sure to leave them as a comment here. We’re recording this Friday, so please submit your questions by Thursday afternoon (PST). Sorry for the late notice!

  1. Ok, question that probably aren’t brought up very often:

    So it brought to my attention that the body when faced with a microbial overgrowth will naturally suppress stomach acid production to a degree in order to reduce the net acid load on the body since microbes naturally have trouble flourishing in a alkaline environment. It was his understanding that the problem was due more to a lack of enzymes (because most of the food we eat is naturally devoid of enzymes from being cooked too long) to fully break down the food and reduce the net acid load from byproducts. Basically he was saying the body tries to deal with the existing microbe overgrowth first by reducing stomach acid production. Any truth to this?

    And yes he subscribes to the paleo style of eating and realizes sodium and potassium bicarbonate are both byproducts of stomach acid production. He is a fan of taking sodium and potassium bicarbonate as a supplement and supplemental enzymes while taking care of the overgrowth with various microbials.

    • I really need to proofread before I post…but you get the gist of what I’m saying hopefully.

  2. Is there a good way to break through weight plateaus without bingeing? The last time I binged, I had a bacon cheeseburger with fries for lunch and a carb-rich Thai meal for dinner and I gained 5 pounds. It took a full week to lose those 5 pounds, which, in effect, was the same as plateauing for a week.

  3. What are your recommendations for vegetarians and vegans. I do not eat eggs, soy, corn, wheat and do minimal diary but do use ghee . I have gone glutten free and feel tremendous difference in myself. Being a vegetarian and glutten free my choices are only legumes. If one has to eat is it safe to soak well and sprout the legumes. Thank you

  4. I’d like to hear Dr. Harris talk about the causes of obesity.

    Also, I’m curious about broken metabolisms and being pregnant and having children. My three kids could not be more different in body type! My oldest, 15 is thin as a rail, girl. My middle, 13 is average, boy. My youngest, 11 is pudgy, since birth, girl. I can’t imagine that their diets are much different, since we take the majority of our meals at home. I’ve always thought their different body types are a reflection of my own deteriorating health over the course of three pregnancies & breastfeeding.

  5. Can you please discuss if Whey protein powder is Paleo, the different types of whey protei being discussed i the Paleo, CrossFit communities as recovery drinks and if any source of whey protein would be suitable for a breakfast replacement if you are tired of eggs, but wish to eat morning protein.

  6. Hi Dr. Harris!

    This one’s about autoimmunity (I know you have mentioned AS and the other spondyloarthropathies in the past on PaleoHacks):

    My father and brother both suffer from undifferentiated spondyloarthropathy, and I came to the paleo diet as a preventative measure a year ago, as I also test positive for HLA-B27. I know that some protocols call for avoidance of eggs and nightshades in the case of severe, arthritic autoimmune disease, but if actual spondyloarthropathy hasn’t been triggered, is it necessary to avoid these foods? I suppose the answer could be an elimination diet, but I was wondering if there’s any evidence for either direction, since I don’t have pain at the current time on a fairly strict, low-dairy paleo diet.

    Thank you, and keep fighting the good fight, as they say.

  7. Hello,

    I am curious as to what your stance is on Toubes’ hypothesis of hypertension. I have only found one study entitled “Insulin’s impact on renal sodium transport and blood pressure in health, obesity, and diabetes,” by Tiwari et al. The information presented seems rational.

  8. A lot of us were convinced of the validity of “low-carb” through Gary Taubes, including I believe Dr. Harris, and my question is specifically about Taubes’ “carbs. drives insulin drives fat” theory. Focusing on fat and obesity (i.e. forgetting about the anti-nutrients of gluten grains for the moment), do all carbs., including rice, potatoes, tubers, root vegetables, raise insulin and thereby make us fat? Relatedly, Taubes argues against the “a calorie is a calorie” theory and I’ve always wondered if he’s saying that we can eat 10,000 calories/day as long as carbs. are low and we wouldn’t gain weight?

  9. I’d like to understand more details about food sensitivity testing — why it’s not recommended and alternatives to identify various foods to avoid. I understand there are various methods to identify foods to avoid from Iga blood tests to Vols testing to nutritional response testing (NRT).

    Thank you

  10. What’s some of the cool stuff you’ve learned over the past few months by diving into the paleoanthropologic data on ancestral diets? Thanks!

  11. Two issues for Dr. Harris:

    (1) I, also, would like to know what Dr. Harris thinks of Chris Masterjohn’s recent posts on the lipid hypothesis of coronary disease, although maybe this would be better as a post on this blog.

    (2) I, also, would like to know how Dr. Harris thinks we can influence the medical establishment to be more open to paleo nutrition.


  12. Hello !

    The topics I would like to hear Dr. Harris to talk about are the following:

    1. Probiotics and prebiotics ? Are they “bunk” ? They only provide ~10 strains which is only a fraction of our total gut population and it seems that they only work when you take them daily. Kefir for the rest of my life anyone ?

    Follow up question would be how to repair antibiotics damaged gut flora ?

    Careful though, Danone might order a hit if you “expose” their super duper probioticlicious yoghurt being more or less, well yoghurt..

    2. Advanced Glycation End Products. Where to watch out, what cooking “methods” might cause them and if they can be form as a result of meal combining higher amounts of n-3/6 PUFA and fructose ?

    Thank you very much,


    • Yes, more on probiotics and prebiotics from Dr. Harris, please. Is there ever a situation/type/dosage when they are helpful? What about fermented foods and drinks? Is any of that “good bacteria” actually making it past the acid in the stomach and to the gut? I know a handful of people on GAPS who are very adamant about either taking their probiotics or at least eating fermented vegetables every day.

      Thank you both!
