ABSTRACT:
A hand-held weight control calculator which allows an individual to quickly and accurately determine the daily maximum food calories allowed for either maintaining body weight or for losing a particular number of pounds as a function of individual weight and activity level. The calculator includes a first indicia bearing disc having a plurality of radially arranged columns displaying daily calorie values disposed on its surface, with each column having a peripheral heading designating an individual weight range value and a registration arrow. A second smaller diameter disc is affixed to the center of the larger disc so that they rotate relative to each other, with the smaller disc including an observation window which is selectively registrable with a particular radial column disposed on the larger disc. The smaller disc includes a plurality of row headings displayed along one edge of the observation window which includes columnized indicia relative to the activity level of an individual such as "very active", "active" or "sedentary" with breakdowns in each activity level row for calories to maintain present weight or to lose a particular number of pounds per week. The device includes a third indicia bearing disc for determining the daily calories necessary for growth for individuals from infancy to adulthood.
