PROLONGED MEAT DIETS WITH A STUDY OF KIDNEY  
FUNCTION AND KETOSIS.

_Two normal men volunteered to live solely on meat for one  
year, which gave us an unusual opportunity of studying the  
effects of this diet.The term “meat,” as used by us, included  
both the lean and the fat portions of animals. The subjects  
derived most of their calories from fat and the diet was quite  
different from what one, who uses the term “meat” as including  
chiefly lean muscle, would expect._

  
_The meat used included beef, Iamb, veal, pork, and chicken.  
The parts used were muscle, liver, kidney, brain, ijone mwrom,  
bacon, and fat._

 **SUMMARY AND CONCLUSIONS.**

**  
1\. 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.**

Hej!

Hur hittade du den här? Det är en studie från 1929. Stefansson, en av deltagarna hade redan 11 års! erfarenhet av att leva på nästan bara kött.

Syftet tycks ju ha varit att utröna om det var skadligt att leva ensidigt på sådan kost. Och svaret var att det var OK!

Synd att ingen gick vidare då, i så fall hade vi kanske sluppit undan HCLF.

Städade lite i mappen "hälsa" i min länksamling och hittade den. ![Flört](../tiny_mce/plugins/emotions/images/smiley-wink.gif)

Stefansson är ju en figur som nämns då och då på forumet.

 De åt främst muskelkött under studien, lever endast ibland. Stefansson föredrog välkokt kött och fick trots detta ingen skörbjugg.
