Compute Trend

Once you've collected a couple of weeks of daily weight readings you can compute the weight trend, chart the progress of the trend, and interpret the chart as described in chapter . We began with a rough estimate of the number of calories to achieve an intended weight goal. The trend figures and chart express reality: what actually happened. By fitting a straight line to the trend, you obtain the actual calorie shortfall or excess, based on your own body's true rate of burning calories, not a number picked from some table.
