METABOLISM IS UNIVERSAL

A mathematical theory attempted to predict the daily maintenance calorie intake (C) for a single male individual. It is a linear function of the weight, based on data gathered during two periods of strict water fasts with different fasting rates. These are somewhat unusual sets of data. FA, the activity factor, is a measure of the amount of physical activity related to the lowest state of body metabolism, RMR. The height and weight of a normal adult male over 16 can be converted to the lean body mass (LBM), the sole predictor of RMR. So, an expression for the resting metabolism rate (RMR) can be derived and extended to Reference Man, and Levanzin, a man who underwent a famous prolonged fast, and the resulting linear formula agrees well with the Harris-Benedict equation for the basal metabolism rate for men. This proves that the RMR for normal adult men was given by extending the theory for the daily calorie intake for one man, so metabolism is universal. It was unknown what the calorie intake was on the non-fasting days, so in the theory it was assumed to be the maintenance calorie intake for the weight on that day. C ≡ (RMR)(FA) and for men 1.3 < FA < 1.9. The activity factor for U.S Reference Man is 1.6.
