As I think, i owe Philip a sedulous answer i once again take the pencil...

Cordaines study on various wild game animals yields to 2-8% fat content
for *whole* animals includeing organs, with a average about 4%
(I posted the reference to cordaines article).
Fat content of animal organs is (even cattle or pork) still low, example:
liver 3.8%, kidney 4%, heart 4%, brain 7.8%, Lung 6.7%.
Wild game muscles have 1-2% fat, that's about 10% of energy.

Thus, wild game animal carcass is rather *low* in energy, agree?

Too low to live exclusively on, in the long term, because to get *all*
2600 or so kcal from 90%protein is hard to bear (also the famous
Stephansson experiment shows that). It's always necessary to have a
seperate source of *fuel* energy. Inuit happyly find fat resources
from arctic fish and mammals (with high w-3 fat) and eat much.
Porks and cattle (and goose...) are artificially fattened (by fedder
and breeding) to reach unnatural high fats- alas in an unfortunate
composition high in saturated fat (obese storage fat) and low in w-3.

SAD people (common western meatatarian dieters) consequentially seek for
"pure" calories like fats (in bacon/pommes/cream ...)
and white bread and sweets to complement the pure proteins.
Too bad these extracts are unhealthy ones.

So where is the real million year long lasting energy source?
Rich in fat animals are a arctic or "northern" ecological niche.
Rich in fats in african savannah were nuts and some seeds.

Eades' article (URL mentioned several times) points out, that even
the fruitarian or seed eater diet of early hominids was high in protein
- higher than today's average. Protein is no bottleneck.
Energy is, for hunters.

What hunting or scavenging has in addition is
the long-chain fatty acids (DHA EPA AA) from eating brains and marrow.
Possibly beneficial for brain developenent.
As mentioned in Eades article. We had a discussions about DHA and brain
here on the list.

If you are interested in real paleolithical nutrition (what IS real?)
