> Your post really got me thinking. With all of these “diets” around, how much of the healthy lifestyle they promote is simply cooking at home and avoiding processed foods? Could it be that all of them boil down to things like cooking a turkey breast or beef roast or ham and slicing it onto homemade bread for a sandwich instead of buying sodium/nitrate/food-glue lunch meat and putting it on preservative-laden Wonder bread?

I don’t think so, because before we went (pseudo) paleo, which, like\*\* rhubarbin’s\*\*, is more like the[Archevore diet](http://www.archevore.com/get-started/), we still ate almost zero processed food. I love to cook, and loved to just as much before this change, but my husband and I both were still a little plump before.

> Again, that list is just what paleolithic nutrition actually _was_, not Mayo’s brand. If someone met most of their calorie needs with hunted meats, fish, and gathered vegetables and fruits, then that would result. It is the result of [current hunter gatherer diets](http://www.cnpp.usda.gov/Publications/DietaryGuidelines/2010/Meeting2/CommentAttachments/Hahn-178DOC.pdf). Someone who eats as many who label themselves as Paleo (or “archevore”) do and promote, will not come close.

Did you actually read that study? In 13 tribes, animal food consumption ranged from 99% of total cals consumed to only 26%. I assure you that the native Alaskans who were still subsisting at the time that data was collected on seals, whales and deep sea fish are not getting most of those calories from ‘lean meats’ (actually, they liked drinking rendered seal blubber) or ‘gathered fruits and vegetables’.

Nor were my Northern European ancestors. Bringing down the biggest, fattest ungulates they could is most of what kept them alive during the long cold winter. It’s ridiculous to even entertain the notion that they stripped the hundreds of pounds of subcutaneous and visceral fat from their kills and discarded it in favor of ‘lean meats’. During the warmer months of course, they enjoyed many plant foods and probably reduced their animal fat intake hugely in favor of seeds, tubers, fruit, honey, etc. But just because the lard fest wasn’t non-stop doesn’t mean their seasonal high fat intake wasn’t ‘paleo’.

Even I’m not that extreme by half - I may eat 200+ grams of mostly animal fat every day, but I also eat plenty of plant foods and moderate amounts of starch.

Hunter-gatherer populations can survive or thrive on vastly different macronutrient proportions. We can usually hunt and gather plenty of fat. In another Cordein paper he found that 97% of modern hunter-gatherers get more than the recommended 30% of their daily calories from fat.

It may be the same thing, but we’re doing it for different reasons. If I were to try a restrictive diet (and I don’t care how you spin it, what you’re doing is restrictive), I would fail miserably, because that’s how my brain works. If it’s a choice, I’m OK with it and I will think it through before I do it. If it’s not a choice, I’ll do it because I know I’m not supposed to.

Why yes, I did. And actually understood what I read.

> For the majority (53% n=122) of the world’s foraging cultures the dietary fat intake would lie between 36 and 43% of total energy (Cordain et al, 2000a), values not dissimilar from current Western intakes …

Note, not higher than typical Western fat, about the same, despite much higher protein intake. The difference, besides more protein per unit fat (pretty much the definition of “lean”) is the fact that the fat is high in omega-3 PUFAs and MUFAs. The saturated fat that is high in modern beef and pork is what is harmful

> [@](#):

> … Hypercholesterolemic fatty acids include 12:0, 14:0, 16:0 and trans-9 18:1 (Grundy, 1997), whereas monounsaturated (MUFA; Gardner & Kraemer 1995; Yu et al, 1995) and polyunsaturated (PUFA, Grundy, 1997) fatty acids are hypocholesterolemic, and 18:0 is neutral (Yu et al, 1995). Omega 3 PUFA have wide ranging cardiovascular protective capacities including lowering of plasma VLDL cholesterol and triacylglycerol (TG) concentrations (Connor & Connor, 1997). Consequently, it is entirely possible to consume relatively high-fat diets that do not necessarily produce a plasma lipid proﬁle that promotes CVD (Garg et al, 1988; Nelson et al, 1995) given sufﬁcient MUFA, PUFA (Gardner & Kraemer, 1995; Mensink & Katan, 1992) and an appropriate o-6=o-3 PUFA ratio (Connor & Connor, 1997) relative to the hypercholesterolemic fatty acids. … Although fat intake (28 – 58% energy) would have been similar to or higher than that found in Western diets, it is likely that important qualitative differences in fat intake, including **relatively high levels of MUFA and PUFA and a lower o-6=o-3 fatty acid ratio** , would have served to inhibit the development of CVD. Other dietary characteristics including **high intakes of antioxidants, ﬁber, vitamins and phytochemicals along with a low salt intake** may have operated synergistically …

(Bolding mine.)

Let me spell this out for you. The study documents that the diet of hunter-gatherers is consistently higher in protein while typically not having any more total fat, and much much less saturated fat. It is high in MUFAs and PUFAs especially omega 3s and 6’s (in particular the former). The high fat Eskimo hunter-gatherer diet is notable (see the articles table 3) in that that the saturated fat content is very low, only 22% of the total fat and 8% of total calories (half the 16% of total calories typical of Americans and less even than the 10% advised as the max by standard medical advice), compared to the MUFA content which is 57% of the total fat and the fairly high omega-3 which is 14% of total fat. (Getting even up to 1 gram of omega 3 a day is rare for most Americans. Even today Eskimos have an intake roughly [20 times](http://www.nutraingredients-usa.com/Research/Eskimo-study-supports-omega-3-for-heart-health) that of other Americans.)

The diet of native Alaskans was very high in MUFA, PUFA (especially omega 3s), and very low in saturated fats that are high in the meat most Americans eat. Let alone compared to how much saturated fat some who are deluded into thinking they are practicing Paleolithic nutrition or “evolutionary metabolic milieu” are eating.

I understand that you don’t get this, but _all animal fat is not the same_. The fat of wild game, the fattest ungulates and of whale or seal blubber _is not the same fat_ as that of modern industrial cattle. Unless you are eating game, seal or whale blubber, or fatty fish, those who are eating lots of meat are eating a diet that has very little to do with what was eaten in Paleolithic times or by extant hunter-gatherers. You can replicate that nutritional balance if you want to, but not by eating lots of modern beef and butter.

The way **rhubarbin** and I are eating actually does emphasize eating lots of fatty fish and avoiding factory farmed meat. I’m not perfect, but 95% of the meat and dairy I eat is pasture fed, and I do make an effort to eat wild-caught fish a couple of times a week.

“very little overlap” between my consumption of animals, nuts, seeds, green vegetables & fruits and paleolithic consumption of animals, nuts, seeds, green vegetables & fruits? My consumption of dairy somehow cancels out the overlap in virtually every other component of my diet? Or do you discount cows, pigs, chickens and fish as being nutritionally different than insect larvae, duck and peccary?

Ooops. Saturated fat is not harmful. Period. Making the rest of your impassioned arguments a waste.

**Renee** , indeed what you describe is closer to a real Paleolithic diet.

**Stoid** , whether or not _Atkin’s style_ is good or bad, is _not_ the point of this conversation. The point is what is or is not similar to a Paleolithic diet and a Paleolithic diet, just as hunter gatherer diets inclusive of native Alaskans, was generally fairly low in saturated fats and high in MUFAs and PUFAs and especially omega 3s. Chicken wings fried in lard does not replicate that diet in any way. Corned beef does not. You are eating a high saturated fat/low carb diet and you are losing weight on it. I make no comment on that other than that I am happy to hear that you found something that works for you. But to call that “Paleo” demonstrates the extremely common ignorance of what the nutritional balance of a Paleolithic (or hunter-gatherer) diet actually was.

As to your request for _controlled studies_ that establish that a diet relatively low in saturated fats and higher in PUFAs reduces coronary heart disease (CHD) … well here is the recent [metaanalysis](http://www.plosmedicine.org/article/info%3Adoi%2F10.1371%2Fjournal.pmed.1000252) of randomized controlled studies on the subject:

> [@](#):
>
> From 346 identified abstracts, eight trials met inclusion criteria, totaling 13,614 participants … These findings provide evidence that consuming PUFA in place of SFA reduces CHD events in RCTs. This suggests that rather than trying to lower PUFA consumption, a shift toward greater population PUFA consumption in place of SFA would significantly reduce rates of CHD.

> temperatures for traditional frying (300 to 350 degrees) and relatively short cooking times (5 to 10 minutes) would have a negligible effect on the formation of trans fat in cooking oil. For example, a recent study conducted to determine the levels of trans fat isomers formed by heat found that in canola oil heated to 500 degrees for 30 minutes, trans fat levels were increased by only 1 percent. Traditional frying at lower temperatures for shorter lengths of time would produce significantly fewer trans fats.

In fact canola oil is an excellent source of monounsaturated fats … like those high in real Paleolithic and hunter-gatherer diets.

And you have made your arguments for what does and does not count.

To which I say: hooey. Not really to specifics, but to the idea that you or anyone knows for sure one way or another. We can use modern hunter gatherer societies as a guideline, but there’s nothing magically infallible about that, far from it.

[This is very interesting reading.](http://www.archevore.com/panu-weblog/2011/1/5/guest-post-professor-gumby-essay-001.html)

It’s rather long, but the bottom line is that equating studies of modern hunter-gatherers and deciding on that basis that we know what paleolithic human beings ate is dicey at best.

> [@](#):
>
> As to your request for _controlled studies_ that establish that a diet relatively low in saturated fats and higher in PUFAs reduces coronary heart disease (CHD)

That’s not what I requested, Dseid, and I think you know that.

You stated, very simply that _saturated fat is harmful:_

> [@](#):
>
> The saturated fat that is high in modern beef and pork is what is harmful

I replied that it is not:

> [@](#):

> [@](#):
>
> Seriously, that myth has been busted up and down the block a few times already. If you doubt that, I invite you to offer up the evidence.

And what you offer does not in any way prove that saturated fat is harmful.

Your study was done because

> [@](#):
>
> …reduced SFA consumption is recommended as a way to avoid CHD [coronary artery disease] However, the evidence from individual randomized controlled trials that have studied CHD events (such as heart attacks and CHD-related deaths) have been mixed and could not support this recommendation.

And after all was sifted and sorted, they still ended up saying:

> [@](#):
>
> Because the trials included in this study looked only at replacing SFA with PUFA, **it is not possible from this evidence alone to distinguish between the benefits of reducing SFA and the benefits of increasing PUFA**. Furthermore, the small number of trials identified in this study all had design faults, so **the risk reductions reported here may be inaccurate.** However, other lines of evidence (for example, \*\*observational studies \*\*that have examined associations between the fat intake of populations and their risk of CHD) also suggest that consumption of PUFA in place of SFA reduces CHD risk.

Which is another way of saying that the rigorous _real_ science didn’t end up proving much at all, so they just fell back on the sounds-like-science bullshit that is always being thrown around on the topic of nutrition but which is really just that old correlation=causation caca.

So if that’s your evidence for the idea that saturated fat is bad, it completely fails. The very best that can be said is that it is evidence that polyunsaturated fat is good, and I know you know that the two things are not the same.

Yeah, I did a double take on that, I’d never heard it before. But it wasn’t my point so I didn’t follow up.

By the way, what is your issue with corned beef, anyway? I make my own and so far I have never used curing salt, (nitrates) so what is it about beef and salt and spices that you think is so un-Paleo? (Assuming your answer isn’t about how much fat is involved)

Indeed **Stoid** , you can find web sites that say all kinds of crazy things. There are many mutually contradictory nutrition claims made all the time - gluten is evil, animal protein causes cancer and raises cholesterol and gluten protects from cancer, and on and on. What’s a person to do? Not make conclusions from crazy web sites. Pretty simple.

You want to believe that your diet of corned beef and chicken wings fried in lard is somehow replicating Paleolithic nutrition. It is not. That fact does not change because you say it is your opinion it is, or because you think that saturated fat is healthy. Again, multiple cites have been given that document that the diet of Paleolithic humans and of extant hunter-gatherers was fairly low in saturated fat, high in MUFAs, PUFAs and omega 3’s, low in salt etc.; the diet you are eating has the opposite ratios. (Yes, the beef with portraying corned beef as a “Paleo food” is its high saturated fat to protein ratio, its low amount of MUFA and PUFA, and its large amount of salt, all of which are the _opposite_ of the animal products eaten in Paleolithic times and by extant hunter-gatherers (game meats and fish mostly). Nitrates would be even farther off from being “Paleo”, of course.

The statement that “Saturated fat is not harmful. Period” is incorrect. To be very precise, a diet higher in saturated fats than in PUFAs is harmful: if one keeps fat constant and replaces the saturated fat with PUFA one decreases coronary heart disease risks. If you want to believe that that “fails” to make the case that increasing saturated fat relative to PUFA is harmful, that increased saturated fat is harmful for CHD risks, then there is not more to say: you’ll believe what you want to believe and dismiss the rest as “bullshit”.

I absolutely agree. Which is why I only pay serious attention to sites that reference their sources, and then I make sure that the sources they reference are reputable, because of course JoBobBlogger saying that X is so because PhineasFacebook said it doesn’t mean anything.

I don’t want to believe anything. Belief doesn’t do a damn thing for me. I want to _know_, so I research and evaluate the information based on who, what, when, how.

> [@](#):

a. My diet is not only those two things, of course, as I said in the very post you are referring to, so you must have seen it, Post #91 (in which I was directly addressing the issue of fat in the diet and the effect of calories and weight loss, by the way, which is why the emphasis on describing the fat content).

b: I’ve also said since the start, Post #74 (The same post in which I said I’d been eating paleo in the first place)

> [@Stoid](#):
>
> I’m not religiously Paleo, I’m more about the carb restriction in general

(Although what I am referring to has more to do with my use of artificial sweeteners and cheese.)

Then I reminded you again in Post # 87, when you felt the need to state (based on nothing) that “corned beef is not Paleolithic”:

> [@](#):

So do you keep responding to me as though I’ve been trying to prove what a perfect example of perfect Paleo eating my personal diet is because it’s easy to feel like a win? (Given that it’s an argument you are only having with yourself, after all.)

c: Are you going to explain your issue with corned beef? Salt and beef are not paleo because..? Chicken wings fried in lard are not Paleo because..? Paleolithic people didn’t eat salt or beef or lard or poultry? And you know this because the modern hunter-gatherers that have been studied don’t eat beef or salt or poultry or lard? Huh?

d: Finally, and most importantly: _You are not the expert on paleolithic nutrition_! And in fact, _no one is_ because we can’t go back. In addition,in much the same way you are being totally selective about what you see in this thread, you are being very selective about acknowledging everything that we _think_ we know based on modern hunter gatherers, ignoring the existence of what doesn’t doesn’t fit into your anti-saturated-fat mindset.

So why you think your unqualified assertions about what is and is not genuinely Paleolithic should be received as gospel, as though you just stepped out of your time machine with the video proof, is a mystery.

> [@](#):
>
> That fact does not change because you say it is your opinion it is

Of course _facts_ don’t change based on my opinions or anyone elses. But we aren’t talking about _facts_. We’re talking about opinions and speculation, because the facts are not available to us. See the previous.

> [@](#):
>
> , or because you think that saturated fat is healthy.

My thinking on anything doesn’t have any effect. And as you know, I haven’t been presenting my “thoughts” as though they were facts. (Ahem…) I’ve been offering cites to the research which prove the facts: saturated fat is, at worst, absolutely harmless, and at best, very healthful, and in either case, definitely _ **not** _ bad, as you asserted.

> [@](#):
>
> Again, multiple cites have been given that document that the diet of Paleolithic humans

No such cites have been given, because they don’t exist. They can’t: we do not know.

What has been offered is the speculation of researchers that is based on what they have observed in some modern hunter-gatherer societies, virtually none of which can be said to be pristine, untouched examples of hunter-gatherer living, (and many of which feature lots of saturated fat in their diets anyway!).

> [@](#):

Please share the “precise” research that “precisely” proves this. Because the study you linked to stated “precisely” the opposite, as I quoted previously:

> [@](#):
>
> Because the trials included in this study **looked only at replacing SFA with PUFA** ,\*\* it is not possible from this evidence alone to distinguish\*\* between the benefits of reducing SFA and the benefits of increasing PUFA

You are ignoring that study’s plain conclusion and inserting the opposite in it’s place. So did you just make it up or simply forget to tell us where you heard it? As something you made up, it’s meaningless. But if you do have a good source for it, it’s no better than if you made it up if you don’t share the source so we can evaluate how reliable it is.

> [@](#):
>
> If you want to believe that **that** “fails” to make the case that increasing saturated fat relative to PUFA is harmful, that increased saturated fat is harmful for CHD risks,

Emphasis mine. What is the “that” that you believe to be so conclusive? Did you just forget to link out to some major study that proves your assertion? As it stands, the “that” refers only to statements you have made that not only have no support, they are precisely the opposite of what the research you originally cited states!

So yeah, total fail.

Are you asserting that, on average, one will take in just as many calories on the paleo diet as on a more typical diet? I know “more typical” diet is vague – I mean, when the average person starts their 30 day paleo trial, is it likely their caloric intake will be going up, staying the same, or going down?

Huh, I never realized there were so many hunter-gatherers patronizing Katz’s Deli.

I suspect that the reason for popularity of the “paleo” diet among a subset of the deluded is the assumption that one can scarf down all the lard and salt that one wants, at a caloric rate equivalent to what one was consuming before, as long as the Evil Carbohydrates are banished. And that’s likely to come back and bite you in the ass.\*

No, I’ve been refuting your assertion:

Which was, as I said, a nonsense assertion, given the caloric density of those foods.

However, what is also true is that because of the carbohydrate changes and restriction, one’s appetite is likely to be noticeably affected, and therefore one is likely to consume fewer calories by naturally choosing to eat less food generally, not because “it’s hard to get enough calories with those foods”.

If that is what you meant by your statement, then I agree with it.

**Stoid** , the subject of this thread is the Paleo diet, not whatever diet you’re following that you consider a variation of the Paleo diet. Please stay on topic. If you want to discuss the differences between the Paleo diet and other plans, please start a new thread.

Which is why we have been discussing and debating [what](http://robbwolf.com/2011/09/29/what-is-the-paleo-diet/) the [definition](http://www.gnolls.org/2365/functional-paleo-a-definition-and-short-manifesto/) of a Paleo diet [actually](http://www.gnolls.org/2226/the-paleo-identity-crisis-what-is-the-paleo-diet-anyway/) is, since there is no clear, consistent agreement about it, either in the scientific community or the pop-diet community.

There is no One True Way to “eat Paleo”, not least because there is not One True Definition of what “eating Paleo” even _means_.

From the Paleo Gurus themselves:

Sometimes the Paleo Diet is combined with fasting or calorie restriction. Some Paleo supporters recommend the consumption of insects.

Here’s a nice breakdown of some “flavors” of Paleo eating:**Loren Cordain – The Paleo Diet (considered the most restrictive)**

[ul]  
[li] **Yes** : meat (emphasis on lean) fruit, veges, nuts, seeds. Recommends fruit, nut and vege with all meals.[/li][li] **Limited** : Eggs, olive, avocado, walnut and flax oil, coffee, tea, alcohol, dried fruit[/li][li]\*\* Avoid Entirely:\*\* Dairy, cereal grains, legumes, starchy vege, processed meats and any salt-containing food (therefore no canned jarred foods), fatty meat, fruit juice and sweets.[/li][/ul]  
\*\*Robb Wolf– The Paleo Solution \*\*

[ul]  
[li] **Yes** : meat, (emphasis on wild caught or grass fed, and includes bacon, sausage and ribeye on his “yes” list) eggs, veges, nuts, seeds. Also ok with canned salmon, tuna.[/li][li] **Recommended fats** : coconut, olive, macadamia avocado oils and LARD[/li][li] **Limited:** fruit, some starchy vegetables[/li][li] **Beverages:** coffee, tea, water[/li][li] **Avoid Entirely:** Everything else[/li][/ul]  
**Art De Vany - The New Evolution Diet**

[ul]  
[li]\*\*Eat: \*\*⅓ raw veggie, ⅓ cooked veggie, ⅓ meat or fish[/li][li] **Recommended fats:** olive and canola oils (canola is considered extremely bad news by many other paleo promoters, this is very surprising)[/li][li] **Limited:** fruit, a little yogurt, nuts[/li][li] **Beverages:** coffee, tea, water[/li][li]\*\*Avoid Entirely: \*\*cereal grains, butter, lard, legumes, processed food[/li][/ul]  
**Mark Sisson - The Primal Blueprint**

[ul]  
[li] **Yes:** Lots of vegetables above all, organic meat, eggs[/li][li] **Moderation:** fruit, nuts, dairy[/li][li] **Recommended fat:** animal[/li][li] **Beverages:** coffee, tea, water[/li][li] **“sensible indulgences”:** alcohol, dark chocolate, high fat dessert[/li][li] **Avoid Entirely:** cereal grains, processed food, processed fats, legumes[/li][/ul]  
**Diana Hsieh - Modern Paleo**

[ul]  
[li] **Yes:** organic meat, eggs, non-starchy vege-with plenty of fat! Yogurt, kefir[/li][li] **Moderation:** fruit, nuts[/li][li] **Recommended fat:** butter, lard, tallow, coconut,olive, bacon grease[/li][li] **Avoid Entirely:** cereal grains, processed food, processed fats, legumes, canned food[/li][/ul]  
\*\*Clear agreement across the board:  
\*\*Paleo definitely means eating non-starchy vegetables and animal protein, not eating cereal grains, sugar and highly processed foods. **Wide range of opinion**

[ul]  
[li]Type of animal protein[/li][li]fat type[/li][li]fat amount[/li][li]nuts[/li][li]fruit[/li][li]starchy vegetables[/li][li]dairy[/li][li]chocolate[/li][li]alcohol[/li][li]coffee[/li][li]degree of processing[/li][/ul]

There’s no question that my diet _is_ Paleo, with the single exception of artfical sweeteners, which have not been an issue in any of this discussion.

Saturated fat has been, however, with Dseid simply declaring that chicken wings fried in lard and my (home cured) corned beef are “not Paleo”. But of course they absolutely are, as you can plainly see.

And on the subject of saturated fat, [this](http://www.gnolls.org/715/when-the-conclusions-dont-match-the-data-even-loren-cordain-whiffs-it-sometimes-because-saturated-fat-is-most-definitely-paleo/) is great reading.

Caloric density of what foods? Yes, avocados and nuts have some calories. What else do you have? One generally doesn’t sit and eat plates of avocados and nuts all day. In the paleo diet, your meat will be leaner and you will eating many more vegetables in place of things like rice or pasta. How is that going to be offset?

Ok, maybe “hard” is a tough word to quantify. You must at least admit that it is hard **ER**?

> Caloric density of what foods?

160 grams of white boiled rice is a cup, and is about 200 calories.

160 grams of boiled potato is about 260 calories

160 grams of lean top sirloin is 300 calories

160 grams of chuck is 536 calories

160 grams of brisket is 655 calories

160 grams of macadamias is 1,160 calories

To get the same 200 calories as you get from the rice takes all of 10 macadamia nuts. I don’t know about you, but 10 macadamia nuts are nothing.

That is what is meant by caloric density.  
The foods you give up have a lower-to-MUCH MUCH MUCH lower caloric density than the foods you embrace, so saying that it’s harder to get the calories makes no sense.

> [@](#):

Your meat will only be leaner if you choose to make it so, as I’ve just spent a lot of time and energy explaining. And if you’re concerned about getting ENOUGH calories, vs. too many, why in the world would you choose to eat very lean meat? (I’ve also spent a lot of energy and time linking to all the research that shows that the knee-jerk belief that fat, particularly animal fat, is unhealthy is wrong.)

And I like my veges with fat, the same way I like my rice and pasta.

> [@](#):
>
> Ok, maybe “hard” is a tough word to quantify. You must at least admit that it is hard **ER**?

I must admit _what_ is harder? That it’s harder to eat 2000 calories when you remove rice and pasta from your menu? I’ve just shown you that that makes no sense.

In order for me to “admit” that, you’d have to be clear about why you are saying it, which you really haven’t been.

The only way in which I believe it is “harder” is this: b **y avoiding simple sugars and starches that jack your blood sugar and mess with your insulin levels, you naturally curb your appetite.** When you are eating lots of sugar and starch, your body keeps telling you to go back for more even when you’ve already had plenty. So yes, when your body chemistry is screwed up and is screaming at you that you must continue eating all day long, it is easier to consume lots of food and therefore lots of calories.
