There are two fat fast threads on the first page of the Tips and Stalls forum. http://forum.lowcarber.org/forumdisplay.php?f=14
Post #2 On this one has the Atkins advice mentioned above: http://forum.lowcarber.org/showthread.php?t=449763 you can have chicken, turkey or eggs with mayo or butter. Or pate if nice and fatty, would think Italy has good ones.

My tip to add would be not to force yourself to eat it all, it can quickly become a bit too much. As with standard LC diets, only Eat if hungry.
