Actually it can be bad to avoid salt entirely, you need salt to replace electrolytes lost, especially in the first week or two. I think Atkins even recommends drinking broth twice a day to help with some side effects at the beginning of the diet. Since you are likely going to be cutting out nearly all processed food your salt intake will naturally drop a lot anyway, i put salt on everything yet when i measure it out it is no where near as much salt as i used to eat in all my ready meals, pizza, chips, etc. It's not healthy to cut out salt 100%, we need a couple of grams at least.
