Values in the table are least squares means and (SE). A linear model with week, group, and week-by-group interaction terms was used to determine whether there were any differences in dietary intake. n does not equal 40 in either group at either time point because several participants did not return diet logs. P values indicate between group differences adjusted for variation due to week. There were no significant week × group interactions. Bolded values are statistically significant.
