      Indeed! Isn’t it great to know there are actual medical professionals out there like Dr. Jack Kruse?

        Yep. Who was it that said…”even if you are a majority of one, the truth is still the truth.”

    I have the pleasure of being friends with Dr.Jack for almost 25years. I to have struggled with my weight and in March Jack invited me to stay with him for a few days and teach me about paleo life style. Before I visited him he had me read Robb Wolfs book and Gary Taubes book, the more I read the madder I got on how I thought I was eating healthy was actually keeping me fat. Jack is light years ahead in this field and I thank you Jimmy for giving him a stage. In the 9 weeks since my visit I have lost 29lbs and am feeling awesome. thanks Jack and thank you too Jimmy!

    Great to hear that Pat, keep it up. I didn’t have that much weight to lose but this approach has given me a level of mastery over my weight that I never knew I could achieve. I am prepairing a lecture on this for my local dental society even as I read this.

    Awesome Jimmy!

    Wish I had a doc like Kruse in my neck of the woods. I’d like to hear more about lepton resistance. I’d like to hear more about calcium in that respect as well. Maybe an encore Jimmy???

      Well, you know the drill, Jim. If you like a particular guest, at the end of the year I open up nominations for “Encore Week” so don’t forget Jack when the time comes.

    It sounds like Dr. Kruse is working on a Grand Unification Theory of Disease. Such as obesity leading to inflammation leading to chronic degenerative disease, with a starring role by leptin.

    I’m a bit skeptical. Time will tell.

    He also said something that didn’t jive with my experience as a geriatrician and hospitalist: Osteoporosis incidence is increasing dramatically.

    A quick Google search didn’t give me U.S. osteoporosis rates over, say, the last 30 years. A reasonable surrogate would be hip fracture rates per 100,000 persons over time. Most of those fractures occur in women with osteoporosis who have fallen. This rate has fallen almost 50% between 1988 and 2005.

      Thanks Steve. So I wonder why Dr. Kruse is seeing this happen more in his field of medicine? Perhaps the reason people have to go see a neurosurgeon is BECAUSE they have osteoporatic issues? Any theories?

    • Jay
      May 27, 2011 | 9:27 am

      Steve….wow. Saying that the decline in hip fractures correlates to decline in bone density loss (or BMD)seems like a stretch to me. I can only think of about a million other variables involved with that conclusion. Here is one…..the population is so fat and lethargic because of LFHC diets they can’t move around enough to break their hip. Or another, the dramatic increase in BMD scans (huge increase) has drawn attention to the problem and the resulting medical protocol has curbed bone density loss (e.g. heavy vitamin D supplementation). Those are the kinds of faulty and incomplete correlations that got us in this mess to begin with. Correlation is not causation.

        It’s funny you mention that, Jay. I’ve got a podcast coming up on June 6, 2011 with Ned Kock from the Health Correlator blog.

    I just started listening to your show a month ago. I’m addicted. I’ve downloaded about 40 shows, mostly encore and paleo weeks. In my opinion, Dr. Kruse is a candidate for 2012 Encore week.

    Hey Jimmy –

    Great interview and thanks to Dr. Kruse. The more docs that are open minded enough to at least consider low carb, the better.

    Keep up the great work and positive energy!

    I have just listened to this interview for a second time. Regarding books, I’ve read a few chapters of Wild Health, how animals keep themselves well and what we can learn from them by Cindy Engel. It is amazing! By carefully observing wild animals, humans have discovered medicines. Jane Goodall said it is “Absolutely enthralling”. I agree.

    Steve…..here is the problem. You’re a doc. Rely on your observation. When I put screws in people spines everyday it is an absolute known. No better way to diagnose osteoporosis. When you diagnosis it it’s based upon a dexa which is a horribly flawed test. You can never rely on it because it falsely elevates bone density because of the degenerative arthritic change seen in the populations you service as a geritrician. I have the unique perspective of operating on young and old. And what I have found as an surgical observation is huge. For six years I have documented what I am finding. Many in my profession like yourself do not see what I see because you are just not looking. Look up the story of Judah Folkes someday. For thirty years he was ostracized for his very simple observation about cancer. He lost his chairmanship of an academic center over it. Then…….thirty years later his work was discovered. Did it matter to him how long it took? Nope. He knew he was correct. Doctors, and you seem to suffer with this too because of your comment, are myopic about breakthroughs. Most believe if it were that simple we all have known about it. Well, Steve……..time to view science through a new optic. It’s called focus on the why to understand the what and the how. You and I were both trained the exact opposite fashion……to focus on the how and what. I stopped that five years. My eyes and observation showed me something that has caused a massive change in my understanding. And that I will share with the world of patients first. Why? Because they get things that begin with the why………and they could care less about the how or what. They only care about “what or how” we know when they realize how much we care. Faced with what I have found and what Dr. Folkes found…….I’m perfectly happy to wait for my brethren to come around while I cure patients. As Jimmy’s reader above posted…….even when you are a majority of one…..the truth is still the truth. I bath my opinions now in the sea of science, because it’s notnbased upon prevailing opinion…….it’s based upon facts. Today’s physicians tell everyone they need a randomized controlled clinical trial to prove causation to treat. I say to you sir…….bullshit. I am a doctor who’s job it is to mesh science and art to get the desired outcome. I never have seen a RCT to tell me to treat a potassium of 3.1 a certain way. We do it because it’s basic biochemical face based upon two million years of evolutionary biology. Remain a skeptic, but patients will read this. And they will see the difference between you and I is but one thing. I think for myself and you rely on opinionated data. Medicine power has been usurped by thinking the wrong way. We need to get back to our core and treat petients based upon principles we know are truths. When I screw a screw in a spine I know I know a lot more than your fancy tests and blood work. Think, change and stop being a good doctor…….reject it and become a great doc. That is what happened to me five years ago.

    I am OFF methotrexate for rheumatoid arthritis. Low carb came into my life because I chose to try and control Type II diabetes. I’ve never YET had to take meds for the diabetes after more than 6 years. An unexpected consequence is getting off the med for my RA!! My theory is that the low carb has controlled the inflammation in my body. Comment??

      Brenda, I am so excited about your post. My husband has RA. Since I retired I have spent more time studying and cooking the low carb way. He has improved and now takes less meds. I have printed your contribution to show him. Years ago I went with him on one occasion, to his doctor. I suggested a few ideas including a Vitamin D test. He looked at me and used the word “ridiculous”. Now my husband looks healthier than the doctor. Thank you Brenda.

    It’s interesting that the focus seems to be moving slightly away from insulin per se, and towards leptin.

    I seem to remember that Gary Taubes in GC, BC/TDD downplayed the more recently identified entities such as leptin and ghrelin, in favour of insulin being the super-dominant one.

    Has the science really moved on in that respect, or has leptin just got “fashionable”? Only time will tell I suppose.

    But if the net result is still that we should be minimising carbohydrates, then, following the KISS/Occam’s razor principle, in practice perhaps nothing much has changed.

    Dr. Kruse is spot on. Lived a low-carb lifestyle about 10 years ago and i lost 30 pounds in 2 months without effort. I lapsed and in the last 10 years I’ve added back the 30 pounds plus an additional 30 – also without effort. this interview has gotten me motivated again. Jack – when you’re back in NY, call me and we’ll compare notes and 6-pack abs.
