Hey i got these before.. i found them extremely confusing, as some are tfr and some are just high protein, some you have to have a multi vitamin tablet with too.. i had said i was in ketosis and wanted to continue with tfr.. but some reason i ended up with both kinds.. they wee too much like food for me and quickly took me off any sorta program. Thats only my opinion thou and i know that other may have been sucessful following this diet.
