Furthermore, it is likely that there are still
undetermined factors that may affect efficacy differentially across
the duration of treatment. For instance, the possibility exists that
fat preferences may change over the course of dietary therapy due
to any number of reasons, ranging from the simple exposure to
novel foods to the modification of biologic conditions that
potentially established the original preferences via the diet.
However, due to our design methodology, we did not re-assess
preferences once the diet was started (i.e., could not expose them
to the carbohydrate food items)
