For sweets and similar junk carbs you'd have the problem of insulin surges
as those items all are very insulin elevating (glycemic- and insulin index).
For the effect of missing protein which I described, pure fats are similar,
btw. Fats and sweets both are pure energy without protein and low in
vitamins.
For sweets there's the additional problem that the body has to metabolize
the carb the two steps (into Acetyl CoA) to a energetically usable
substrate, whereas fats don't require this step. This first step of
glycolyse requires a very complex enzyme complex (pyruvate dehydrogenase)
which depends on several vitamins and coenzymes, in amounts related to the
intake. And these items are processed out in the "refining" process.
The same caloric amount of junk fat would be better than the same amount of
junk carb.

I myself live on the boundary of eating fat and getting adequate protein.
I like to eat a lot of  fats (normally  some 40% of all energy) and I don't
eat protein concentrates.
Natural plant protein souces contain from about 100% energy (I mean 100%
energy = some 2400kcal, for 100% RDA protein=some 55g).
From 100% in nuts over 150% protein in grains, over 210% in legumes to 500%
in vegetables (broccoli).
Fat fills the gap between 100% and 150 or 210 or 500% protein, depending on
how much of each I get.

Most people I tell about the 270g are astonished that it is so much. A very
big steak plus some sausage, but not everybody eats a steak everyday.
Ordinary meat portion sizes (in a steak house for ex) are smaller. I recall
125g.

Yes that's  right.
Not generally healthy but particularly in the aspect of protein. (also some
vitamins, b2 and b12, maybe b6 maybe iron and zinc).
As a energy source it's not so good (lean meat has 700% protein per
2400kcal).
Therefore, alas the gap of energy to be filled after 100% protein has been
eaten is much  bigger.
And alas *can* be eaten as "crap" energy.
Of course many meat eaters eat much more than the 100% RDA protein and much
fattier meat. So the gap becomes smaller and filled with more
protein calories and the slaughter fat from the animals.
Paleolisters would generally almost close the energy gap by very fatty meat
and some little other calories.
Keep in mind that the fat in the muscle of fattened animals is less ideal
due to lack of EFAs.
That's why Cordain consequentially suggests to replace the slaughter fat
with some added EFA containing fats (e.g. rubbing with flax)
and adding some more paleo-carbs. In my view it's only logical to do so.

Ok, which nutritional factors?
Protein of course (with the additional advantage that muscle protein causes
less allergies than many plant proteins).
If you analyse the plan of a only meat day (1600g lean meat for 2400 kcal)
you see, which vitamin/mineral is high.
It's b6 (160%),  b2 (180%), zinc (430%), iron(330%) , phosphor and
potassium. And b12.
From whole plants you easily also get a high value on these, except for b2
and of course b12. For zinc and iron only if no resorption blocker is active
(phytin).
So the meat, seen as a "vitamin pill" has protein, b12, b2, less important
b6. Plus zinc and iron for phytin suffering subjects.
If a vegetarian doen't manage to equal that out by choosing the right other
sources  he or she will fail after some time.
For b12 it will be a very long time of up to 15 years.

Btw if you check what the meat "vitamin pill" is lacking, you easily see
what can be missing in a high meat (or in a SAD meat) diet.
That's what has to be equaled out in a high meat approach.

When I discovered this paleo lists (and vergy good is paleodiet) I learned
of a lot of problems that come with plant foods as well. A good reason to
care.
Besides that, well scandals are there.
Low-fat I even didn't hear about (no big topic over here). IMO low fat is a
(less ideal) EFA  preserving strategy and could work in this way.

I'm again surprised Amadeus. It almost sounds like you are defending
meat..... :)

It has it's advantages.
