Abstract
The recovery process of the lower basal metabolism after the war was reported in report I (Jap. J. Nutr., 10, 108, 1952), which was based on the data measured between August 1949 and 1951. After that the measurement has been continued up to present. This report gives an acconunt of the process of the basal metabolism measured after that until December 1953. The reusults were as follows:
1) The B. M. R. which was in lower level until August 1950 began to rise and it kept the constant level there after, as shown in figure 1 and 2. The B. M. R. for subsequent three years between 1950 and December 1953 were averaged into 33.7Cal./hr./sq.m. in subject S. S. and 33.3 in S. N.. These values are 4 and 6% higher than the lower B. M. R. in preceeding years respectively.
2) The recovery of the declined B. M. R. needed about two years after the latter of 1948. when both sujects could begin to get diet of the nutritional allowances. It indicates that the recovery of the declined B. M. R. in consequence of prolonged food shortage needs a few years long to reach normal.
3) The seasonal variation of the basal metabolism in this data showed that in winter was 5% higher and in summer 4% lower than the average.
4) Respiratory quotient showed the seasonal variation: in summer higher than in winter in the subiject S. N. whose body weight was constant through a year, but it was not clear in the subject S. S. whose boby weight showed a seasonal change.
