One of the fundamental problems of human Calorie Restricton involves measuring the degree of caloric restriction. In animal experiments, scientists measure how much a control group eats and then use that as a basis for calculating the percentage of caloric restriction of the experimental animals. For humans there are no controls, but it is possible to use the Harris-Benedict or the Mifflin-St Jeor energy expenditure equations as a basis for estimating caloric needs for a person of any specific height, weight, age, sex, and activity level. The caloric requirements for a "control twin" may be calculated by selecting a weight corresponding to a Body Mass Index (BMI) of 22, which is the middle of the normal range, in combination with any specific height, age, sex, and activity level.
