Patent ID: 7264472

Claim:
An analog device which graphically simulates qualitative relationships between human diet, exercise and body weight, said device comprising a pressurized fluid passing through a suitable conduit as a means to simulate an energy flow and also to power said device, said energy flow being conducted in series through a variable diet-energy restrictor as a means to simulate changes in food intake, said food intake designated as diet energy, a diet-energy rate meter as a means to display said changes in diet energy, said simulated energy flow being further conducted in series through a second fluid rate meter designated as displaying exercise-energy rate, said exercise-energy comprising all energy used by the body for physical movement, respiration and body heat, a variable exercise-energy restrictor as a means to simulate changes in said exercise-energy, an energy magnitude meter connected to qualitatively simulate energy magnitude between said diet-energy rate meter and said exercise-energy rate meter as a means to display said simulated human body weight resulting from changes to said diet-energy rate and/or said exercise-energy rate.
