Hi, I have done Akins's / Low carb before and lost around 3 stones . I am considering doing it again but I have a concern about potassium levels doing this diet . When I first did Atkins I got admitted to hospital with heart palputations and blood tests showed that my potassium level was very low and was put on a potassium suppliment for a week and I quit the diet , I got admitted again a few years later with the same symtoms with low potassium and this time I wasn't on the diet and they put it down to the water tablet (duretic) I was taking for my blood pressure (I had been on this when I was first admitted but they didn't pick it up). I know you have to drink a fair bit of water and this can reduce you body's salt levels but has anyone else had similar symtoms and is there anything I can take to keep my potassium levels up
