The FastDay Forum

I am fasting today and had nothing to eat all day until I had dinner a couple of hours ago. I feel like my heart is beating extra hard (not faster, just very strong heartbeat) after I ate. Anybody else experience this? Do you know why this is? Sudden surge in blood sugar maybe?

I can remember a few fast days that I got anxiety just waiting for dinner. Perhaps that is what you are feeling. Make sure you are drinking lots of water. Not eating or drinking leads to dehydration.

don't think it's anxiety and I have been drinking plenty all day
Did some googling just now and apparently fasting raises adrenaline levels. That could cause increased heart rate.

hi @icefast, yes, it could be a surge in blood sugar and insulin - what did you eat?

I ate a low fat hot dog, very white bread so the blood sugar had a kick
