My parents were in "Independent Living" for a while and all the food was low salt. It seemed like every day I visited one resident or another was falling and being carted off by ambulance. My normal-weight mother fell twice, first breaking her hip, then hitting her head. We brought her to live with my sister, and only because she was having her blood pressure taken every other day by an RN, OT or PT did doctors allow us to wean her off two BP-lowering meds. Without the white coats, she had readings less than half of normal - so low that two of them went out to their cars to bring in another BP monitor, assuming the first one was faulty. No, that's what no salt and salt-excreting meds do to a person! Needless to say, we got her off the meds and salted her food normally and she never fell or fainted again. She wasn't as low carb as me, but my sister's home is real foods South-Beachy.
