Wondering about the safety and effects of
using meat as a sole source of nutrition,
I found this year-long study:
http://www.jbc.org/content/87/3/651.full.pdf
'PROLONGED MEAT DIETS WITH A STUDY
OF KIDNEY FUNCTION AND KETOSIS.'
J. Biol. Chem., 1930, 87:651-668.
BY WALTER S. MCCLELLAN AND EUGENE F. DuBOIS.
From the Russell Sage Institute of Pathology
in Affiliation with the Second Medical (Cornell)
Division of Bellevue Hospital, New York.)
(Received for publication, February 13, 1930.)..."
A Summary of the results is on pg.667 of the study
and following:
'...Two men lived on an exclusive meat diet for
1 year and a third man for 10 days.
The relative amounts of lean and fat, meat
ingested were left to the instinctive choice
of the individuals.
2. The protein content
varied from 100 to 140 gm.,
the fat from 200 to 300 gm.,
the carbohydrate, derived entirely
from the meat, from 7 to 12 gm., and the
fuel value from 2000 to 3100 calories.
3. At the end of the year, the subjects were
mentally alert, physically active, and
showed no specific physical changes in any
system of the body.
4. During the 1st week,
all three men lost weight, due to a shift in
the water content of the body while
adjusting itself to the low carbohydrate
diet. Thereafter, their weights remained
practically constant.
5. In the prolonged test, the blood pressure
of one man remained constant; the systolic
pressure of the other decreased 20 mm. and
the diastolic pressure remained uniform.
6. The control of the bowels was not
disturbed while the subjects were on
prescribed meat diet. In one
instance, when the proportion of protein
calories in the diet exceeded 40 per cent, a
diarrhea developed.
7. Vitamin deficiencies did not appear.
8. The total acidity of the
urine during the meat diet was increased
to 2 or 3 times that of the acidity on mixed
diets and acetonuria was present
throughout the periods of exclusive meat.
9.Urine examinations, determinations of the
nitrogenous constituents of the blood, and
kidney function tests revealed no evidence
of kidney damage.
10. While on the meat diet, the men
metabolized foodstuffs with
FA: G ratios between 1.9 and 3.0 and
excreted from 0.4 to 7.2 gm. of acetone
bodies per day.
11. In these trained
subjects, the clinical observations and
laboratory studies gave no evidence that any
ill effects had occurred from the prolonged
use of the exclusive meat diet...'
"We must admit that our opponents
in this argument have a marked advantage
over us.
They need only a few words to set forth
a half-truth; whereas, in order to show that
it is a half-truth, we have to resort to long
and arid dissertations". ~Author Unknown

Thank tq for posting that.
In five years, the truth about LCHF Ketogenic diet will find its way out to the mainstream. Even if it doesn't make it out to the mainstream media, which is biased, because of "carb advertising" ~ the truth will filter out by people on this diet and others seeing it's results and it will continue to get out through the internet.

I think one needs look no further than the example of the Inuit people, who live in arctic regions of the world. Meat and fat is their primary source of sustenance, and yet they have relatively normal life expectancy. I say "relatively normal." Life expectancy lags behind other groups, but is mostly due to harsh living conditions, injury, and smoking, rather than dietary causes.0

Yah, totally agree with ya, Dan.
With all the ethical medical research
ongoing and easy online publishing...
Truth will Out, yes?
Thx4yer comments!

I'm reckon you already know
this, but for the benefit of our
LC community knowledge base...
One of the men in this year long
study was Mr Vilhjalmur Stefansson,
Arctic Explorer, Ethnographer,
and Author of numerous books
about the Inuit and his experiences
and observations living amongst them.
Stefansson's book on NA Inuit dietary
observations is a fav read:
The Fat of the Land' enlarged edition of
'Not By Bread Alone' 1960, online at:
http://tinyurl.com/lt5kuuv
It speaks to LCHF principles that
Dr Peter Attia reckons the NA Inuit
were eating 90% dietary Fat and
very low carb, yet still had the
muscle building part of their native
diet zoned.
Thx for yer comments, Mr Steve!0
