Art De Vany's New Evolution Diet definitely promotes a moderate fat diet. For example, he recommends throwing out some of the yolks from eggs:

Eggs are healthy, but you should skip the yolks now and then. The yolk is mostly fat...

He also makes the following statement:

because the truth is that no fat is particularly good for you

I'd like to understand why he says this - he never explains how he arrived at this conclusion. If he does explain it, could you point me to the section in the book where this occurs?

Well, I'll take his egg yolks if he doesn't want 'em. ;) – red_leaf Apr 23 2012 at 18:57

He is tossing out the wrong part, the part with all the vitamins and healthy fat and cholesterol.

Isn't the egg white also a gut irritant for some people (in large amounts)? Something about trypsin inhibition, avidin, or something else... – Kamal Jan 21 2011 at 22:28
Agreed, and the whites are pure protein. I'm more worried about excess protein than excess fat. – Wozza Jan 22 2011 at 0:18

I think it's dangerous advice to tell people to toss the yolk. It makes no sense and only shows that De Vany still believes in the lipid hypothesis. – Paleo Seb Jan 22 2011 at 3:54

Egg whites contain avidin which binds biotin. High intake of egg white can lead to biotin deficiency. – Eva Jan 22 2011 at 5:52

If you don't toss the whites you should make sure the whites are cooked solid. – Kurt G Harris MD Jan 22 2011 at 16:20

A big part of the Paleo community still believe in eating egg whites and choosing lean meat and I think that it's a sad affair. What are you left with when well known people on the community tell you to watch the carbs as well as the fat? Eat a low calorie diet? A high-protein diet?

Most people on Paleo Hacks understand the importance of fat as a macronutrient providing energy, but more newcomers are lead to think that fat is still somewhat of a problem.

Robb Wolf tells people to eat lean meat because he thinks people aren't going to choose grass-fed and that it's better to eat lean meat than fatty grain-fed meat mainly because of the o-3/o-6 ratio. I think he's wrong in thinking that most people are not willing to do the extra little step of choosing grass-fed most of the time. After all, if those people chose to eliminate gluten grains completely, I see that as a way more difficult change to make for most people.

I also tend to believe that fatty grain-fed meat isn't all that terrible, especially if you compensate your lack of o-3 with fatty fish or a small amount of good quality fish oil.

I haven't really been able to make the switch over to grass-fed, though I wish I could. It's a money issue as well as the fact that my husband actually thought the grass-fed steak I got him at Trader Joes was "the worst steak he ever had" and he didn't even know it was grass-fed, so it wasn't a mental thing. So, on conventional meats, I try to stick to some leaner cuts and get my fats from coconut oil and bacon. – sherpamelissa Jan 22 2011 at 14:06
At my Whole Foods they have a deal for $1 off per pound of grass fed ground beef when you buy 3 or more pounds. So I've just gotten used to buying a giant pile of beef and taking off a hunk at a time and sometimes freezing what gets leftover. – Casey Feb 16 2011 at 19:39
Due to Omega 6 content I prefere to get my fat from other (ghee, butter, heavy cream, coconut oil) sources. – Ikco Feb 16 2011 at 20:38

Yes, interesting to see folks heating up olive oil for cooking, eating lots of nuts, chicken, pork, and then avoiding fatty grain fed meat. Eliminate those other omega 6 traps and eat the cheap beef without regret. And sure, pony up for grass fed beef, certainly no harm there. – Tim Rangitsch Feb 18 2011 at 4:59

How can he say that no fat is particularly good for you. That's just ridiculous. Without fat intake, you would die. The body requires fat to survive. In addition, without fat concurrent fat intake, fat soluable vitamins will not be digested. The body is designed such that regular fat consumption is required to maintain healthy function.

And don't get me started about maligning egg yokes. That's the healthiest part.

And apparently he hasn't read all the literature and research showing saturated fat intake is not connected with any ill health and does not contribute to blood cholesterol problems either. So what is wrong with saturated fat intake again? Devany is not making sense.

Doesn't the body only require a few essential fatty acids. Just as it can make carbs from protein or fat, the body can make any type of fat from sugar, no? – mac389 Jan 23 2011 at 2:44

I don't think he really eats that way. If you look at the menus he posts and put them in nutrition data software they are pretty high in fat. He's eating a good diet accidentally.

Melissa, could you possible elaborate on some of the menus he posts? I'm guessing this is in his pay-site. I've been curious as to what exactly he does eat, because obviously he's doing something right... – Daniel Mar 9 2011 at 5:17

FWIS, just found this quote attributed to DeVany on another website: "I may eat 4 eggs at a time, so tossing a yolk just limits the surge of saurated fat into my bloodstream. Eating some yolks assures that I do get fat. Yolks contain fats of all kinds and are not really biased to Omega 3 content and the eggs that are are expensive. Easier and cheaper to eat some fish of take a capsule. The average of fat intake is close to meaningless; the surges are more important. Eating just half or fewer of the yolks dampens the surge of fats hitting your bloodstream." – Brad Warner Jan 21 2011 at 20:13
FWIW, that is. :) – Brad Warner Jan 21 2011 at 20:13
Surge? This is what happens to FFA after a meal of butter (top line) or oils, 40g carbohydrate and no fat is the lowest line: 2.bp.blogspot.com/_xlflFL230eI/S6Rxwhh147I/… Triglycerides might increase (4.bp.blogspot.com/_xlflFL230eI/S6R5PO2hw_I/…) but we all know that it's carbohydrate that drives them up in the long term. – David Moss Jan 21 2011 at 22:00

It works for Art... I just wish he wouldn't talk about it. He's the exception not the rule.

link|flag
This is a HUGE problem in the diet and nutrition community for seeking validation of theories in individuals. It's a problem of generalization. What works for Art doesn't necessarily work for everyone else. One of the few people who spends any amount of time talking about this problem is Doug McGuff. – jbone Jan 24 2011 at 21:11

I believe the reason he feels this way is because in this day and age we are still really lazy. We sit all day. He still believes that your source for energy is coming from the same source as the rest of the Paleo followers out there, but he is just suggesting that you watch your fat intake a little bit.

I mean he looks pretty good for his age. With that being said, I eat all my egg yolks. Also with the whole lean meat thing. I think this is based on conventional meat. It is high in fat. And not the good grass-fed fats.

My 2 cents

I feel that it is all apart of the misconception that "fat = bad news" our culture and society have adopted as an essential dietary guideline. Almost like a phobia if you will. People are going to buy De Vany's theories and ideas because its easier to have someone else reaffirm the belief that for example, eating the egg yolk is bad.

People are hesitant to accept that a yolk or any other form of fat for that matter can AND is nutritionally beneficial because of the basic social science phenomenon that people are afraid of change, and anything that threatens their learned behavior and attitudes towards something causes dissonance. Then again, no one truly enjoys feeling confused so by ways of coping, De Vaney does a great job in educating young and old minds alike on nutrition. However, he fails because he clearly hasn't enjoyed a hamburger with a fried egg on top.

I have a sense many people here on Paleohacks or in the Paleosphere in general REALLY up their fat intake. While that may work for some, in general, most of us following such a lifestyle are still eating a high fat diet, since we're defining a high fat diet in calories, not grams.

If one eats 100 grams of carbohydrate, 100 grams of protein, and 100 grams of fat, it's still a high fat diet. 400/400/900 by calorie breakdown. It's still above 50% calories from fat. Plenty of health benefits.

Perhaps Art de Vany identifies the fear surrounding the fat-phobic nature of the current healthcare system, and like Robb Wolf, who advocates "lean meats...etc etc," is simply providing an easier buy in for folks. Egg whites and lean meats is still a shot above donuts and little Debbie snack cakes.
