Table 194. - A. W. W., April 25, 1907. Sitting. (2-Hour Periods). Butter And Potato Chips

Amounts, 85 grams butter, 104 grams potato chips; nitrogen, 1.05 grams; total energy, 1,285 cals. Fuel value: Total, 1,276 cals.; from protein, 2 p. ct.; from fat, 82 p. ct.; from carbohydrates, 16 cals. Basal values (March 15 and 21, 1907): CO2, 50 grams; O2, 41 grams; heat, 155 cals.

1Subject ate food in 26 minutes.

J. J. C, March 12, 1910

The experiment on this date was the first of a supplementary series with the butter and potato chips diet carried out in Boston three years after the Middletown experiments. The subject took but 38 grams of butter and 91 grams of potato chips; the results obtained are given in table 195. Although the basal value was determined on the same day as the values after food, and the general trend of the results was similar to that of the results obtained in the previous experiments, we do not feel justified in laying great emphasis upon the data, owing to the general irregularity in muscular repose shown by this subject, especially in the sitting position. The experiment may be said, therefore, to give incomplete evidence as to the increment in the metabolism due to a predominatingly fat diet.

Table 195. - J. J. C, March 12, 1910. Sitting. (1-Hour Periods). Butter And Potato Chips

Amounts, 38 grams butter, 91 grams potato chips; nitrogen, 0.76 gram; total energy, 798 cals. Fuel value: Total, 791 cals.; from protein, 2 p. ct.; from fat, 79 p. ct.; from carbohydrates, 19 p. ct. Nitrogen in urine, 0.30 gram per hour.1 Basal values (March 12, 1910): CO2, 24 grams; O2, 20.5 grams; heat, 75 cals.; respiratory quotient, 0.86. Nitrogen in urine, 0.14 gram per hour.

1Sample included amount for about 2 hours preceding eating of food.

2Subject finished eating 22 minutes after beginning of this period. The eating occupied 16 minutes.

L. E. E., March 14, 1910

A larger amount of butter was taken in this experiment than in the preceding experiment, 92 grams being eaten with 114 grams of potato chips. The detailed results are given in table 196. Although L. E. E. was a trained observer on the staff of the Nutrition Laboratory and accustomed to remaining very quiet, he was in this experiment distinctly restless. The increment in carbon-dioxide production was found in the first and third periods; the values for oxygen consumption and heat production were also irregular. For some as yet unexplained reason, the metabolism in the second and fourth periods was shown to be basal by all three factors. The total increment for the carbon-dioxide production was 6 grams, for the oxygen consumption 13 grams, and for the heat production 36 calories, thus confirming the evidence of the experiments previously discussed that the ingestion of a predominatingly fat diet has a positive effect upon the metabolism.

J. R., March 21,1910

After the ingestion of 95 grams of butter and 92 grams of potato chips, slight increments were found in carbon-dioxide production throughout the 5 hours of the experiment and in most of the periods for heat production, with somewhat large increments in oxygen consumption. The results of the experiment, which are given in detail in table 197, thus supply further proof as to the stimulating effect of a fat diet upon the metabolism. In the three experiments with the Boston calorimeter the last one with J. R. is the only one in which there was a noticeable increase in the pulse rate after the taking of food. The change was from 70 in the preliminary period to 73 after food.

Amounts, 92 grams butter, 114 grams potato chips; nitrogen, 0.69 gram; total energy 1,518 cals. Fuel value: Total, 1,512 cals.; from protein, 1 p. ct.; from fat, 86 p. ct.; from carbohydrates, 13 p. ct. Nitrogen in urine, 0.47 gram per hour (in first three periods).1 Basal values (March 14,1910): CO2, 27 grams; O2. 22 grams; heat,1 70 cals.; respiratory quotient, 0.88. Nitrogen in urine, 0.56 gram per hour.

1Sample included amount for about 2 hours preceding the eating of food. 2Heat eliminated corrected for change in body-weight, but not for change in body-temperature. 3Subject finished eating 20 minutes after beginning of this period. The eating occupied 16 minutes.
