Salt helps many people with "carb flu."
Volek and Phinney have a treatment for carb flu: Salt. They say the kidneys switch over when carbs get lower and dump sodium and water. I drink a cup or two of full salt broth most days and salt my food heavily and did not get the carb flu. Salt has had the same treatment as saturated fat by my colleagues in medicine. My blood pressure is 115/75 with all this salt, so I am not the slightest bit worried. Give it a try! reference: The Art and Science of Low Carbohydrate Living.
