Salt affects so much in the body. Diabetics must watch the intake as it affects metabolism. Salt reduction is drastically needed for high-blood pressure reduction. So much of high-fat foods are also high sodium foods. Processed meats, cheeses, snacks, frozen diet dinners, diet foods use sodium to make them taste better.
Cutting fat AND sodium need to go hand in hand. Unfortunately, these are the things that got us all here to begin with.
A wise woman once said "The food that made you fat will not be the food that makes you thin."
Try sea salt to reduce sodium to start. It tastes much saltier and is lower in sodium than ordinary table salt.
I find that if I seek out the taste of pepper first before salt, I can feel satisfied shaking the pepper on my food. It will always be a struggle for me.
