1. A method of obtaining information about a physiological parameter, comprising:

  • collecting data from an implantable restriction device over a time period, the collected data containing information about values of a parameter sensed within a body during the time period; and

    in a data processing device, analyzing the collected data to determine information about a physiological parameter for at least a portion of the time period, wherein the analysis includes calculating a rate of change of the values of the sensed parameter for a window within the time period;

    calculating a rate at which the rate of change is changing; and

    dividing the rate of change by the rate at which the rate of change is changing and multiplying by a period of the window to obtain a predicted amount of time until the values of the sensed parameter will have a rate of change that is about zero, the value of the physiological parameter when the rate of change is about zero representing a baseline value.
