Understanding blood ketones

[Lpeck]

I just started checking blood ketones this past week. Coming off a 48 hour water fast, I ate a keto prime rib meal that was rather large. My reading the morning after was 1.0. then I proceeded into a 75 hour water fast, checking twice a day. At 60 hours my reading was 1.9. then it was 2.4 at 75 hours. I proceeded to eat a small keto meal, adding a pumpkin cookie at the end. Here’s my question…when I woke this morning my reading was 3.7. I expected it to go down because I ate at near midnight. How does this work? Is 1 better than 3? I saw the bell curve nutrition ketosis chart… confused

Don’t chase numbers. Higher numbers have no correlation with fat loss or other keto benefits.

I’ve read that. Just wondering why.

Your burning glucose/sugar (what little you do get from an external or internal source) at a much faster rate because your in Ketosis, in addition to the the intermittent fasting breaks! You have really good running median numbers for blood ketones!

See MY WHY:

Start with your Why

My why? I consider keto a way of life not a “diet” so I treat my nutrition as if I already have cancer or diabetes! Recent scientific research,* literature,* and other studies* are strongly indicating that our body was not intended to burn excessive exogenic sugar or refined and processed carbohydrates. I will never ever go back to the way I was eating before or cheat! *EPIDEMIOLOGY: EXCESSIVE EXOGENIC SUGAR (glucose) INTAKE including HIGHLY PROCESSED CARBOHYDRATES (gluconeogenesis; including …

Science tells us that over time, fasting up regulates some hormones and down regulates others, ultimately restoring our metabolic health. I think this this happens to a small degree during bouts of extended fasting. It primes our body to readily accept nutrients when they are reintroduced.

I’ve noticed when doing extended fasting, interrupting it with a single meal often doesn’t effect my ketone levels. Provided I return back to fasting. If I have a 2nd or 3rd meal, especially if it’s carb heavy, my ketotic state will be effected.
