At one point in my low carb journey, when I had lost a fair amount of weight, there came a day when there were potato chips just sitting there at my place. I couldn't stop thinking about them. It was a very powerful craving. At this point I had declined carby foods many times, but I really wanted these potato chips. I gave in and ate some, because I would have been consumed by thoughts of them for hours if I hadn't.

Recently the dots connected for me. My low carb diet was too low in salt. My cravings for potato chips back then were from my body trying to balance itself.
