In your example calculations you assume the entire daily intake of fat is Omega-3/6.  I was under the impression it's about 1/3 of a persons fat intake, with the rest being saturated, mono unsaturated, etc.

Just curious . . . you say 30% of calories from fat, but what are the other percentages?  I know you dislike wheat (as do I), so where do the carb calories come from?

Two comments.  

First, there's no way on this green earth that the typical paleo diet was limited to 21% of calories from fat.  They ate very few carbs and favored the fatty portions of the game animals they hunted.  The lean portions didn't have enough fat-soluble vitamins and were often fed to animals or discarded.

Second, the amount of polyunsaturated fatty acids in most of those historical diets isn't 100% of fat calories.  The fat fraction of calories includes fully saturated (FSFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA).  The ratio of Omega 6 to Omega 3 is only concerned with those two groups of PUFA in the diet.  

Of the fraction of PUFA in the diet, some will be Omega-3, Omega-6, and Omega-9 fatty acids.  So it all depends on the fraction of fatty acids that are PUFA.  Fish oils are about 25% PUFA.  Grain-fed animal fats are 5-15% PUFA.  Grass-fed animal fats are 1-2% PUFA.  Modern vegetable oils are from 40-80% PUFA.  Tropical oils (coconut, palm) are 10-20% PUFA.

In my paleo-modeled diet, I'm consuming 60% of my 3000 daily calories from grass-fed animal fats, so 0.6-1.2% of 2500 calories in fat weighs 2.0-4.0g.  Since grass-fed meat PUFA's are 3:1 w-6:w-3, I need to take in an extra 1000-2000mg of Omega-3's to restore a 1:1 balance between Omega-3 and Omage-6 fatty acids.

For people with smaller fat intakes, just staying away from processed vegetable oils (replaced by foods with lower Omega-6 levels) would reduce the amount of supplemental Omega-3's needed to rebalance the PUFA intake.

I am an urban Indian but we do not consume any vegetable oil but only small amounts of rapeseed oil and our omega-6/omega-3 ratio must be close to 2:1.
Urban Indians have just been brain-washed by Doctors and Advertisements for seed oils and more educated they are, more likely they to overconsume seed oils.

What do you think of Dr Lands and his model that relates CHD mortality with %n-6
in tissue HUFA ie AA/(EPA+DHA+AA) in tissues.

It is at http://efaeducation.nih.gov/

Is the ratio of short-chain ω-3 / -6 really important? (linoleic vs linolenic) Or is it just the ratio of the long-chains (arachidonic vs EPA/DHA)?

You tell us that flax oil doesn't make much difference because the body can't efficiently lengthen its short ω-3's into EPA.  But then doesn't it follow that large amounts short ω-6 don't make much difference either?  It's the same inefficient pathway.

OH, I'm not complaining..it's only human to do so though..the same way when we were kids and did everything we could to run away from mom and that spoonful of cough medicine.

We've grown up now and chase ourselves with that spoon.. I used to take Cod liver oil though I imagine that is different.  Now I take a rather pleasant supplement by Neurovi , it's very high quality and sits well with my stomach lol.  Plus it contains just the right amount of DHA to EPA..I've tried limiting Omega 6 intake but it is sometimes difficult so hopefully I can help my body by giving it more of the "good stuff".

The omega 3 is essential for our organism. But they too often make defect in our plate. A deficiency that can have numerous consequences on health:  cardiovascular unrests, depress, problems of vision. Zoom on the risks of a deficit in omega 3.

i read ,the scientific calculation by dr david sim cardiologist and vascular ,which he proofs that we need 10 times as much omega 6 then omega 3

Worst of all with an enormous preponderance of omega-6 over omega-3 are urban Indians, who experience among the highest rates of heart disease in the world.

Is Jimmy still eating eggs for every meal in order to lose weight?

Dr. Davis, How true is this statement?
"before resorting to muscle tissue, the body will burn fat. If you have no body fat, (or even very little of it), then eating carbohydrates is a good idea. If there is fat to burn, it will be burned first. Our entire body runs on sugar, but you can turn fat into sugar and sugar into fat, depending on the current needs of the body"

No - he is off the eggs, but somewhere up around 282lbs.  Jimmy is indeed a great connector and does well with podcasts and interviews but his own diet - and as a consequence his weight - remains a problem.  He remains obese and as such is not a great advert for low carb.

THANKS for the plug for my new "Fan Club" associated with my podcast, Dr. Davis.  I certainly hope to indeed connect fans of "The Livin' La Vida Low-Carb Show" with more of the behind-the-scenes happenings to get them involved in the interview process, share transcripts of past episodes, and even let them hear sneak peak audio of not-yet-aired podcasts.  I'm excited to make this little something extra available to those who want more.

As for the the anonymous criticism about my weight, yes I weigh more than I would like to at this moment.  This is not a secret and I've been quite candid about this publicly because there are many who face the same frustrations of doing everything right and yet seeing very little progress on the scale.  While I'm seeking to rectify those issues by lowering my calories to 1800/daily and engaging in regular exercise, the fact remains my health is immaculate.

High HDL, low triglycerides, low percentage of Small LDL particles, stable blood sugar, normal blood pressure, a heart scan score of ZERO, abundant energy and so much more.  While the focus tends to be on weight as the key measurement in someone being healthy, I think that's as shortsighted as telling someone a low-fat, high-carb diet is the only way to lose weight and be healthy.  Again, I'd like to weigh less than I do now but it's difficult to argue that the way I'm eating isn't making me healthier than when I weighed 400+ pounds in 2004 on three prescription medications.

Re: Jimmy's weight - it's Jimmy's business!  The guy does a massive amount of work, as highlighted by Dr Davis' post, promoting the many and varied strains of low carb eating, and he does so because he has first-hand experience of the benefits of doing so.  Sure HE might not want to be where HE wants to be with HIS weight, but it isn't like he is ht eonly guy pushing the low carb mantra and peddling snack oil is it?

Jimmy, I'd have no doubt you could get to where you wanted to be (or closer to it at least), if you gave up on the stuff that you do.  But the rest of us would be poorer for it.  A run a very small and very much part-time blog in this field and if I put in the amount of time Jimmy does with all his work, I doubt I would be able to maintain the other aspects of my life that I enjoy so much.  It is a sacrifice Jimmy makes.

One last thing, and Jimmy may disagree with me on this... At one point in time, Jimmy's lifestyle lead him down the obesity pathway.  One aspect of this, and one that I try to promote in my line of work, is if you go down that road, there is no guarantee you can come back out of it.  Things like the consumption of industrial seed oils can lead to fat cell hypertrophy & hyperplasia... size AND number of fat cells increase.  Stay in this state long enough, and there is high chance you will never fully undo the damage done.  You can certainly imporve your health biomarkers as Jimmy has obviously done.  But you might not necessarily be able to return to an ultrathin body, no matter how much you desire it.  There is a degree of ingorance from people who just automatically assume that because one is eating low carb, they should look like a Crossfitter all the time and failure to do so means that low carbing is a failure also.

Well said Jamie!  I totally agree.

Nothing measures up when compared to perfection. It's better to compare real-life choices and their likely consequences whenever possible.

If someone was 400+ pounds and on medications on their old diet, and 120 pounds lighter, energetic and off the medications on a different diet, the different diet must have some benefits. I prefer to think in terms of progress, not perfection.

Jimmy, Jamie and Lori


AMEN !!!!

I know Jimmy personally and he is a sincere, hard-working nice guy.

We are all learning new lessons in nutrition and how to manage diet, navigating all the landmines in the commercial food that we are sold.

Jimmy's unquestioned role in this has been to facilitate the discussion, bringing differing viewpoints from interesting people like Gary Taubes and Jeff Volek.

Personally, I am grateful that we have someone like Jimmy Moore who acts as amiable host to our discussions.

i love Jimmy's podcasts. In fact i subscribe via itunes. He never fails to have intelligent guests. Especially in the last year or two he has had many paleo people which is great. I like to see the focus on good-health-all-around entering into his lowcarb world, rather than the sole goal of weightloss that i feel many atkinsers etc have. Anyway, he's doing a great job. and he has been for quite some time now. His weight? Who cares. Jimmy, dont sweat it! you've lost all that, your health numbers look great and you are leading a life that benefits many. I think you can be satisfied.

Train wreck/drama queen. Needs to lift free weights or join a cross fit gym…quit making excuses..

"Train wreck/drama queen...quit making excuses..."

You got that right!

Thank you so much Jimmy for the help you provide to all of us.
I am an uruguayan and follow your podcast from Uruguay LA.
Thanks again.
Jose.

If not for Jimmy Moore I would never have heard of Dr Davis, Mark Sisson, Stephan Guyenet, Robb Wolf, Dr Briffa, Fred Hahn and so many others.  I would never in a million years have thought to include strength training in my lifestyle.  I wouldn't have learned about the impact of sleep on health and mood.  Without the information Jimmy Moore brought into my life, I'd still be Vitamin D deficient, undermuscled, underslept and unhealthy.  Instead I've grown strength and muscle, ditched lifelong allergies and have had only one cold in the last three years.  (I work in healthcare and get coughed/sneezed upon constantly, so this is no insignificant fact.)

Jimmy is humble, funny, candid and generous.  Sure, we'd all like to include "stunning physique" in our list of personal qualities, but some of us just have to be satisfied with excellent health and an ongoing commitment to pursue optimal body composition.

For me, Jimmy Moore is a treasure.

Kudos to Jimmy for all his good work. I completely agree with Jamie above.

Anonymous trolls, just go away, or at least show a little spine and put your name.
