For me, going low carb did not effect my salt intake too much, I don't think... Most of the foods I had to cut out were on the fruits, sugars and starches side of things.
When I do snack now, its not necessarily healthy stuff I am eating, its just low carb
I'm talking pork rinds usually with American or spreadable cheeses and or potted meat, dill pickles, (especially hot cauliflower pickles - I eat a jar a week), etc. - ie stuff insanely high in salt / sodium. I've always been more of a salt lover than a sugar lover. For my meals I always salt my meat and veggies and cook them with bacon, (often in the salty bacon grease which I never throw out). I also use MSG, (Accent), which is very similar to salt and is high in sodium. Now on top of all that I'm making my own "ramen" using shirataki angel hair pasta with chicken and beef bouillon.
I'm not too worried that I don't get enough sodium. As I learned more, I became more concerned about my potassium and started taking a half teaspoon of French's NoSalt as a supplement per day.
I just remember reading that if you consume sufficient salt when you go low carb, you won't have that initial huge drop in weight. I am of the belief that my initial wight loss had little to do with sodium and probably had more to do with glycogen.
I have to do some more studying I guess.
