Blood color while fasting


(Homer Fish) #1

I’m on day 6 of a water fast and have been checking my blood glucose levels. I started at 93 on day 1 then day 3 or 4 was around 65. My blood was a rich dark red as normal on day one but on day 4 was more of a lighter color.

I tested again the next day and was a darker color again but blood glucose 61 so even lower. Monday, today I’m at 50 and color is dark too like normal.

Do the ketones darken the blood?

More likely to be hydration levels.

Interesting. When I was testing blood, I don’t think I ever looked at it. It goes be a good idea though.
