No empty dir in tar log

Hi I'm writing a shell for backup the file in my system that are changed after yesterday.
The tar logfile is scanned and every row goes in an oracle database table.

The problem is that when the tar find a directory without file, it puts the directory in the logfile.

My command is:

for DIR in $( cat ${INCLUDE_FILE} )
do
tar -cvzf ${FILE_TAR} ${DIR} --exclude-from=${EXCLUDE_FILE} --after-date="${YESTERDAY}" > ${OUTFILE_OK} 2> ${OUTFILE_KO}
done


Where

INCLUDE_FILE -> file with system dir (every dir have a different tar)
FILE_TAR -> path/of/the/tar.tgz
EXCLUDE_FILE -> file with system dir to exclude from backup
YESTERDAY -> Yesterday date
OUTFILE_OK -> Log
OUTFILE_KO -> Error log


For example the dir /etc/cron.weekly/ doesn't have file changed but this dir goes in the tar log.

INCLUDE_FILE="/path/to/include/myFile.h
