  • Caloric energy balance monitor
    Patent number: 6506152
    Abstract: A caloric energy balance monitor uses calories expended during rest and activity, and calories consumed from food, to compute a predicted change in the user's body fat percentage. The predicted change in body fat percentage is then compared to an actual change in body fat percentage to iteratively compute a correction factor that is used in subsequent measurements of net caloric energy balance.
