Weight Change vs Bite Count
There is growing evidence that average daily bite count does relate
to weight change over time.
The following figures show data from 3 independent studies in which
subjects (N=82, 40, and 39) used bite counting devices over multiple
weeks (2, 16, and 26 weeks respectively).
The relationship between average daily bite count and weight change
per week was found to be between 0.00007 and 0.00020 lb/week per
daily kilocalorie, indicating that as subjects consumed less bites
they lost more weight.
These slopes were not statistically significantly different from a
fourth dataset in which doubly labeled water was used to measure
average daily energy intake (also shown in the figure).
|Clemson, slope = 0.00018 (R=0.09)
||MUSC, slope = 0.00020 (R=0.13)
||USC, slope = 0.00007 (R=0.10)
||CALERIE, slope = 0.00013 (R=0.22)

The data for the above analyses is available in the following links:
The CALERIE dataset is stored
at Duke University and is also freely available.
