Been at this LC for almost six months now. Keep between 30-60 carbs.
Recently though when hungry especially if I have missed breakfast (so a 16 hour fast) my heart seems to give occasional very strong beats. As though it's jumping out of my chest. It just lasts a few seconds and doesn't seem to happen on the days I have breakfast. I think it's possibly a mineral imbalance. Have taken magnesium but actually it seemed worse after that. I have cut back a bit on salt due to hypertension!! Just wondered if anyone could shed some light.
