I know what you mean about snacking, I think that when meat is cured it is done in one big chunk so that the process does not permeate the meat completely but seals the outside of the meat so it doesn't spoil so quickly.
The carb count for most prepackaged meats is written on most packages or you can ask the deli person for a label or atleast to look at it for the counts of stuff you order. I have heard that the cooking process in bacon does burn off the sugar, but that may be too good to be true.
I like to cook my own meat (it last better than packaged stuff) cut it thin and put a little flavoured cream cheese and green onion and roll it up and eat it or microwave it for a few seconds and eat it with a knife and fork. If you slice boneless skinless chicken breasts in two pound them flat and cook up several at a time they make a quick snack too, just add some sour cream, a little low carb salsa, or even some salad dressing (ranch and feta or good) and there you have snacks that will get you through those snack attacts. They can also be wrapped around cheese and ham and microwaved, add a little mayo flavoured with some herbs and you've got something to munch on the will fill you quickly.

P.S. this type of eating is a never ending learning process. I know that there are certain foods that will lead me to binge and certain ones that cause me too stall. You may have to experiment for a while before you find out what works the best for you. Good Luck.
