I wouldn't worry about the inch or so. You are probably looking at most 5g a serving, more like 2-4. It's a holiday and sinc eyou are staying away from the higher carb dishes, don't sweat the ham. Try to balance the rest of your day though to be lower carb, and maybe before you go have a large salad.

You can also play good guest and bring something without. An appitizer tray filled with nuts, fresh veggies and dip would work great. Or an LC dessert to have beside the pumpkin pie.

I am going to make an LC feast for thanksgiving, but realisticly I know the carb count for that meal will still be higher then I would normally have. For the entire meal though it will probably still be less then one slice of regular pumpkin pie. Compramise is always good
