If you have just started low carb, you have probably noticed that you are having to go to the toilet more? This is because carbs help the body hold onto water, you are probably a bit dehydrated - think hangover without the pleasure! More sodium in the form of ordinary table salt will help. If it doesn't, you might try a bone broth to give you more minerals. Home made is best but Bovril will do at a pinch. I wonder about the value of the low salt campaign, which is resulting in almost tasteless food products. Maybe by concentrating on getting to people to cut down on carbohydrate, we could have the taste back in bought foods.
