Ketones rise and then fall on 2 day fast

[Karen_Black]

I just did a 2 day fast wth ketones starting at 1.7. At 24 hours into the fast my ketones were at 2.0. At 40 hours my ketones were at 3.1. At 44 hours I had 16 oz of hot matcha tea, no sweetner, 1/2 tsp apple cider vinegar and a 1/2 tsp of lemon juice. Then at 48 hours my ketones read as Lo on my Keto Mojo. My blood glucose was 88. Any ideas why my ketones dropped off?

No idea, sorry.

That’s quite a drop. Normally, is suggest an immediate retest. You might also want to repeat the fast and testing work the same conditions (tea)

Good idea. I have since eaten and retested 4 hours after eating… I am currently at 1.6 ketone level. Not sure I’ll redo the 48 hour fast this weekend.

Ketones are in constant flux. Measure hourly for a day. Check out this guy’s ketones over the course of a couple days.

Fatigue after eating, week 3

I’ve been on this diet for 3 weeks, and suddenly started getting substantial fatigue after my first meal of the day. (Egg whites, 1 ounce beef, avocado and 2 good yogurt with chia seeds) Any idea what is causing this? I plan to test my glucose levels (87 fasted last week when I had my blood work done) Below is my Ketones level since beginning the diet. Strange chart as my diet hasn’t changed much throughout.

Yeah, but I’m not sure if they should have stopped that much from the tea. But, a good practice is to test before eating or drinking anything, other than water or unsweetened (straight) tea.
