I’ve been doing fasting off and on since 2016 but I’ve begun again in earnest after struggling with my sugars/stress level all summer. The longest I’ve done so far is 69 hours - largely due to my sodium issues. I have low sodium issues in general (get it from my dad) so I have to salt everything all the time whether I’m fasting, keto, or eating whatever. In the past I end up feeling so crappy from lack of sodium that 69 hours is the longest I’ve been able to go.
Yesterday I started doing a 9 day fast (with broth and coffee) and drank 4 cups of broth yesterday to try to make sure my salt was up - which was about a total of 3g of sodium. Last night my heart rate, which normally sits in the low 60s, ramped up to low 80s and stayed elevated around 69-71 all night (normally around 60). Just before bed I felt like I had a heart palpitation - which don’t normally bother me since I started getting those around 23 due to my PCOS - but this one felt much stronger.
Should I be cutting back on sodium intake or has anyone else had similar issues? Everything else is great - my blood sugars are perfect, my ketones are sitting pretty at 3.3. Also wondering if it could be the caffeine’s fault but I had coffee in the morning and the heart rate stuff didn’t kick in till 9pm.
