I am experiencing severe leg cramps at night. I started taking Magnesium a few years ago and the cramps mostly stopped. I've been Primal for about 14 months and have lost around 80 lbs. The leg cramps came back about a month ago beginning just in my feet and, last night, a bad one in my calf. I eat very low carbs, below 50 grams I'm almost certain, but I haven't kept track of how low in grams or how many calories since I've always been obsessive about "figures" and I liked the freedom of the Primal way. I am beginning to wonder if leg cramps can be caused by too little carbs. If that is the case, how could I add some carbs and still lose weight?
