5.1 Ketones at 30hrs, did I do something wrong?

(Scott Wild) #1

Hi, new here.
I did a 24hr fast a few months ago and enjoyed the process. I wanted to do a 48hr next but things got weird.
Here’s the play by play with details from my Ketone tester:

1/10 6:00pm - Last meal.
1/11 7:30am - 11.7mg of KetoCaNa
1/11 8:00am - 2hr walk.
1/11 10:00am - 0.5 mmol/L Ketones
1/11 4:00pm - 2.3mmol/L Ketones
1/11 6:00pm - 6mg of KetoCaNa
1/11 9:00pm - Sleep
1/12 2:30am - Woke up feeling jittery, couldn’t sleep until 5:30am.
1/12 6:30am - Felt really weak and jittery. Motor skills were uncoordinated. Felt as if I would pass out.
1/12 6:45am - 5.1 mmol/L Ketones
1/12 7:00am - Ended fast early, felt too bad, ate breakfast.

So what happened folks? Should my Ketones have been at 5.1 after only 30hrs of fasting?
I took care of myself and drank lots of water. What happened?
Any input would be greatly appreciated.
Thanks,

Maybe someone can correct me, but it looks like you drank ketones. Adding more ketones to your system seems like it would increase your ketone reading with a meter.

I may be completely wrong, but that’s my guess.

Good question. If so, how much would still be in my system after 13hrs? I can’t imagine they stay around that long, but I don’t know anything their half life.

Not an expert, and I don’t test. I believe the amount in your system depends on how effectively you’re using them. What is your reason behind drinking the ketones? As an experiment, you could try fasting again without them to see how you feel. Supplement with some lite salt if you want to make sure you’re getting some sodium and potassium.

I’m also not an expert, but I see no need for the exogenous ketone consumption.

(What The Fast?!) #6

Agree. No need for exogenous ketones. Cut those out and try fasting again - you shouldn’t be jittery.

No expert, but maybe more water and salt, and or bone broth

Did you test you blood glucose as well? If so, what did they show?

(Duncan Kerridge) #9

You’re forcing your body to produce and use ketones by fasting, and then pouring more in. I’d ditch the exogenous ketones.

I don’t know how long the ingested ketones stay in your system either, but I have found through experimentation that if I eat something with sugar alcohols in it, my breath meter readings are really high for a good 24 hours.

Exogenous ketones wear off after a couple of hours…

Everyone seems to want to blame the exogenous ketones without asking further questions…

What’s your current height and weight?

Did you supplement any electrolytes?

How often had you fasted before this?

Do you use exogenous ketones and have any negative reactions when not fasting?

(Scott Wild) #13

Thanks jilliangordona,
I’m 5’9" and 165lbs.
I drank filtered water with a pinch of salt here and there.
I’ve only done a 24hr fast previously.
I did not use any exogenous ketones previously and had no ill effects.

I’m really not sure what happened this time.

When fasting I personally don’t need to do anything but fast for ketones to go up higher than usual. I also found that after I have a couple shots of vodka it raises my blood ketones. I have early morning reading over 3 to 3.5 which is not usual for my morning reading. Just leave out the exogenous ketones when you fast.

You’re messing with your body’s natural ketone production. Enough said.
