Does anyone have any info on Low carb/Paleo diet and leg cramps? I've been thinking about this since one Paleo-blogger stated that he gets leg cramps if he goes below 50g or carbs per day.
I've been lowish carb for almost a year, but a few months ago dropped the grains and this has forced the carbs lower. The other night I got a nasty night-time cramp - my calf is still tender 3 days later. I also have had small cramps when walking every day since. I have had those from time to time w/o any preceding nocturnal cramp and a friend advised me to get more carbs.
The thing is, I had issues with nocturnal leg cramps since first pregnancy and I was not eating low carb then (I was told to eat more bananas which did not help). Although over the next 10 years I was able to control them and it was not too much of an issue. I have never experienced day-time cramping until I cut carbs. These can be quite bad - they are small, but usually happen when I am out walking, so I still have to get home and my muscle will hurt for several days after. Also, I experience occasional muscle twitching in my legs.
I'm wondering what the mechanism would be if it is lack of carbs so I can rule it out (or not).
*update: Thanks for the responses. I am giving everyone a vote as I don't know which answer is best...but I have a lot to go on now! I'll try looking at magnesium/mineral and fluid intake... still wondering if it could be something else though as I have not lost any weight since changing my diet (hence no water loss?). I hate to measure and count, but I've given in and started using fitday to keep my carbs around 100g/day - no cramps since, but still feel things are not quite right with my calf muscles. I also noticed my protein was a bit high- could this cause cramps? *
