Okay,
Background: I have been on the keto diet for almost 9 months and was not diabetic before starting (probably insulin resistant still). It has went well so far. I am 6’3 and 280ish lbs, started at 415 and I am 30 years old. I have done multiple 3 day fast and have been able to do strength resistance training and walking with no issues. I also started running about 8 months ago and have completed 3 5ks.
On my current fast I tried running for the first time. I was 63 hours into my 80ish hour fast and found out I was having some issues. My heart rate is typically high (180 when running) and today hit 174 but felt more stressed. Hopefully this rate should drop with additional weight loss and cardio health. I hit a wall at about 1.5 miles today that was not typical. I also had patchy skin and a dry itchy forehead that I believe may be from acetone sweat from ketosis.
I have been supplementing with kosher salt, magnesium citrate and potassium chloride. Only coffee and water on the fast out side of the electrolytes. Any tips of information around why this occurs/occurred? Are there ways to avoid the wall in future fast?
Thanks for any help,
Bomb
