The file contents is not generated, because you try to loop the result set a second time, without resetting the internal file pointer. Uses mysql_data_seek before the second loop.

i added this but still nothing happens

<?
mysql_data_seek($objQuery);
while($objResult = mysql_fetch_array($objQuery))
{
    fwrite($objWrite, "$objResult[Protein],$objResult[Fat],");
    fwrite($objWrite, "$objResult[Carbohydrate],$objResult[Sodium] \r\n");
}
echo "<br>Generate Text File Done.<br><a href=$filName>Download</a>";
fclose($objWrite)
?>

Have you tried:

mysql_data_seek($objQuery, 0);

If that fails, just write the file inside the first loop.
