Two thoughts come to mind.
One is that I follow the Atkins suggestion that if I am truly hungry after I've eaten (say 20 - 30 minutes) then I have somemore to eat. Interestingly enough I often find that more is VERY LITTLE more until I suddenly feel full.
Second is BRATWURST! I'm not sure what's mixed with the meat but very, very often it's sugar & wheat hidden in there and of course that can trigger cravings.
...IMHO.
Hope this may be some help.
