1. A method for instantaneously and continuously assessing real time energy balance for fitness management comprising, in order:

  • (a) collecting food intake information for actual or expected food intake of a user over a specified period of time and contemporaneously converting the food intake information into food intake energy units for the first period of time, wherein the food intake units are based on relative energy content of one food compared to another without relying on standard caloric values;

    (b) collecting by a device activity information for actual or expected activity by the user over the specified period of time and contemporaneously converting the activity information into energy units for the user for the first period of time, wherein the collecting for actual activity is achieved by wireless transmission by a motion sensor and the motion sensor is a programmable accelerometer, the functional status of which is altered by;

    (i) programming independent of a magnetic field;

    (ii) collecting deflections of the accelerometer during the activity in various positions inside the engineered environment such that it records motion associated with one type of activity while excluding movement characteristic of another form of activity;

    (iii) applying a multiplier to the accelerometer deflections collected in (ii) to assign a weighted value indicative of the level of effort exerted during the activity;

    (iv) saving deflections from each type of movement such that deflection counts are segregated by activity type and determining the amount of relative energy expended by the user during any given time period in the activity type;

    (v) transferring deflection counts and relative energy expended to a device; and

    (vi) processing the deflection counts and relative energy expended for display by the device;

    (c) instantaneously deriving, via a computing device, a calculated currently determined constant that reflects efficiency, which is a rate at which the user extracts energy from the food units that can be referenced against predicted and actual changes in weight, wherein the constant is a surrogate for intrinsic metabolic rate;

    (d) instantaneously calculating by an algorithm from the calculated currently determined constant in (c) a predicted energy balance for the user, by;

    1. calculating a ratio of an amount of activity units expected divided by an amount of activity observed;

    2. calculating a ratio of an amount of food units expected divided by an amount of food units observed;

    3. weighting the ratio in (a) against the ratio in (b) according to goals of the user; and

    4. modifying the weighted ratio in (3) by a rate at which the user performs the activity/work(e) instantaneously predicting a change in weight from the predicted energy balance; and

    (f) determining fitness level of the user based on the efficiency of energy consumption.
