I'm going to be honest here. I have not watched it and I'm not going to. I am trying to focus on positives and watching stuff like I imagine this to be will likely put me in a bad place. I think we should all stop wasting our time on discussing him, it does no good. And all the negativity makes us look bad.

I watched it yesterday but I knew going in that it was going to be a train wreck as I had read/heard about it for weeks already. Was I impressed/shocked/dismayed? No, none of the above, but I can say that at least for whatever it's worth, his speech was far more understandable than his blog tends to be. I think there's something to the cold thermogenesis concept and I definitely think there's something to eating paleo for better health but I don't think the surgery/MRSA injections helped his cause any and, in fact, probably caused a lot of people to tune out and write him off completely.

As others have mentioned elsewhere on this site, I worry that he's going to lose his license to practice medicine by publicly announcing the MRSA portion of his experiment. It just doesn't seem wise for a doctor to use himself (not to mention his family) in such a blatantly unorthodox way.

I wish him the best and I think there may be something to some of his theories but I don't think he's going about things the way a professional should.

I'm really glad you are talking about this guy, cos as a newcomer the stuff he says is pretty confusing! He says that paleo made him look fit, but he was still suffering from imflammation, and that if we don't all take high level magnesium supplements and sit in freezing cold baths then, however 'ripped' paleo makes us look, we could still fall down dead of heart attacks at any time. Plus, looking at the video, I could not get why his 'wheat belly' came back if he was still following paleo.

At least, that's what I managed to get from his very rambling talks and page - I don't really understand WHAT he's saying most of the time. That kind of stuff could (a) make paleo sound way more complicated than it is (I find it fairly straightforward actually), and (b) make people worried that paleo is simply a cosmetic thing for people who want to look good rather than feel good / be healthy / live long.

All in all, I decided that what he was saying could not be right (or was too complicated for me to understand!). I have been listening to 'conventional health wisdom' all my life, in the form of doctors, media, etc, and I never felt well. Paleo makes me feel GOOD, and that's enough for me!

I found his talk disorganized and with poor use of slides. He would really benefit from public speaking lessons. He just doesn't have any reality distortion field natively, so he needs to work on the charisma.

The key issue is whether or not the leptin-melanocortin pathway works as he says it does. Cold thermogenisis, the paleo diet, ketosis, the use of cold with surgery- practically everything he supports is not his own. They all are, however, acceptable protocols that have brought good results to many people, so you haters aren't really doing anything but engaging in personal attacks.

Of course, I don't see why the surgery on himself particularly proves anything, unless he just felt he had to know what he was about to put his patients through.

To a large extent Kruse seems to be trying to figure out how to promote a message on the internet. TedX wanted edgy, crazy even. They like stories, want the personal. For a while now I've notice most TED talks have very little actual content.
I wish he would have stood up there and traced out the pathway. This stuff is complicated- I just ran into a part of it while reading a book called the Honey Revolution, and realized in the process that Kruse could be right about NPY if carbs are low. The likelihood that there is a study performed under those conditions is virtually nil.

So, Kruse goes there and tells stories. I like Tyler Cowen's TED talk, where he admonishes the TED conference goers about the dangers of telling each other a bunch of stories. Am I going to get really upset with a neurosurgeon about stories? No. It is very obvious he spends most of his time thinking about other things. He assumes the stories are what will get his message out. I will save my ire for the story professionals. Meanwhile, I much rather see some constructive criticism on the proposed pathway rather than Kruse's style.

I'm biased against Kruse and I can't be fair. Full disclosure up front.

That said, I did NOT like that video.

I watched it, I agree with GurlzLuvSteak, it could have used a great deal of editorial focusing. Could have been shortened to 1/3 as long and kept the important reveals and trimmed the WTFery antics out (MRSA!?).

Still, I'm even more interested now in finding someone with communication skills as presenting a good introduction on how to implement cold adapting strategies. Much like Mark Sisson has done in the past couple weeks in his multipart Intermittent Fasting posts. Until that day, I'll keep my eyes and ears out for someone ELSE to bring the goods on cold.

I am offering a tip of the hat to him for getting it on my radar though.

I know almost nothing about Dr. Kruse's recommendations, but I don't why he should be treated any differently than anyone else.

There is either credible evidence to support his claims or there isn't, and whether or not that evidence exists is a useful topic for discussion.

Speculating about his credibility, or passing judgement on his relationship with his family, is nothing more than gossip.

I haven't seen it, so I'm not commenting on the video. But as I read this thread it struck me - how would any of use have reacted 30 years ago if someone said they had just injected botulism into their face?

Injecting oneself with toxic substances isn't unprecedented. Dr. Barry Marshall injected himself with bacteria to prove that ulcers are caused by bacteria when current wisdom believed they were caused by stress. Sure enough, he developed ulcers. Then he took antibiotics to heal himself. Won the Nobel prize in 2005, along with J. Robin Warren for this work.

Like the man or hate the man, who cares. Judge him on his work, not his style. He's not making the Paleo community toxic. Those who spend their time gossiping about him are taking care of that nicely.

I loved it!!!!!!!

Extremely entertaining! Reminds me of Disneyland after Dark! http://www.youtube.com/watch?v=HEe2_wr6TQ4&feature=related

He leads by example. You ignore him at your own detriment.

I know Jack and his family very well. I have been to his home many times and he to mine. Our families have traveled together. We have worked together for 13 years. He is (by his own admission) very polarizing and controversial. He is not trying to change individual thinking, but trying to change the world. Some of his claims may pan out to be untrue, but this is the scientific method. All great scientists have theories that pan out to be untrue. Thomas Edison proposed that we run DC current to individual homes. That would never have worked. This is how we learn.

I can attest that he does indeed practice CT daily and follows his diet plan very religiously. I saw his transformation first hand from obese to fit. He is a healthcare professional, a dentist, and a neurosurgeon trained at some top institutions. He is a fine Neruosurgeon and actually did surg. on my mother. Very little of what he says is a lie. He is known for hyperbolization at times, but his message is real and should be considered.

As for his wardrobe, we tease him all the time about it. I was once with him when a friend said to him, "I like your jeans, Jack. Too bad they don't come in men's versions". So the clothing jokes are not new to him.

It is unclear to me why he writes incoherently at times? I think he is just so eager to share his knowledge, he posts things without first reading them. I think he should be given a little slack with the personal criticisms--he really is a great guy.
