Has anyone gotten this? I’m 5 days into a fast. Ketones were 5.0 mmol/L a day ago.
Keto Mojo “Hi” reading

Nope. The highest I’ve ever seen was 6.7 on the sixth day of an EF.
Edit: This made me curious, went to the user’s manual on the KetoMojo website, page 30. The “hi” indicates your ketones were above 8.0 mmol/L.
If it were me, I might repeat the test just to see if this were replicated. Not out of concern, just curiosity.

It’s not anything to worry about unless you’re BG is through the roof, too. You’re not being very efficient with the ketones, but I bet you feel good.

I have just gotten the “Hi” reading and knew from the manual it meant something above 8.0. I am about 65 hrs into a fast and got a BG reading of 66, so I am not concerned. Assuming only 8.1 ketones, this gives me a Glucose-Ketone Index of .45 – which is nicely within Dr. Seyfried’s “therapeutic zone.”
I had this happen just once during last month’s fast, but it was only about 36 hours in, with ketones settling down into the high 5’s and low 6’s for the remainder of the fast. I theorize that maybe once fat burning goes into hyperdrive maybe fewer ketones are needed. I started that fast already in mid 3s-range ketosis, while I think I was in the .5-1 ketone range when I began this fast,-- which may explain why it took another day to hit the Hi range and the therapeutic GKI.
I am doing monthly 3.5 day (90-94 hrs) fasts as a proactive health measure and do IF with keto macros the rest of the time.

I got “Hi” yesterday and today. Yesterday I repeated the test and it came in at 7.1. Today, I tried 4 strips and kept getting “Hi”. I’m 6 days into a water-fast, so I am assuming I am over 8.0 at this point, with a Blood Glucose (BG) of 71…would be nice if their strips supported fasting. Also, their “Ketone Graph/Scale” is misleading, because it says you are in Ketoacidosis at 10+, but that is only true if you have high BG. So assuming I am at 8.0, I have a pretty stellar GKI of 0.49!

Found this after I saw ‘Hi’ on my meter for the 1st time. This is 115 hours into a 120 hour fast. That’s five days. I do these once or twice a year.
This time I am trying a bit of ‘dry fasting’ Sarah Pugh did something similar (blog on YouTube) She talked about doing a 7 day fast where the last 2 days were ‘dry’.
So I thought I’d try it. All very god so far. There is some proper science behind dry fasting, very new to me, the body makes its own water, from… FAT, so all very good really.

Be careful about the dry fasting. I know it’s said to speed up autophagy and all other good things about fasting but it’s hard on the body. Only dry fast I ever did gave me awful lower back pain at the two day mark. I’d planned to push it to a full three days but started to feel truly strange and unwell. Very interested to hear how it goes for you!

Thanks for the interest.
Yes, I’ve done the research and I am experienced with normal fasting over lots of different time periods. I’d recently read a lot of literature which was new to me. What got me interested was Sarah Pugh mentioning dry fasting when she did a 7 day fast. (her blog is on YouTube) Even she didn’t really like it, but she knew exactly how it really works, down in the weeds, so to speak.
It might be very effective, breaking down fat to create deuterium free water, but I’m not hooked. I tried a dry fast on the 1st day, a Friday at midday, and at the 24h mark I had terrible dry sore throat, so I stopped and eat normally for a few days. I restarted a normal fast on the following Monday, at midday. (My wife is away in Corsica walking the GR20, that’s always the best time for me to do longer fasts, saves a lot of money and having to cook too!) That was perfectly fine and then on days 4 and 5 I switched to dry fasting, as Sarah had done. I could always go back to wet fasting at anytime if there were any issues. This time it was perfectly fine. I finished just now, Saturday, midday. No problems at all. All that was different was the ketone numbers got higher and higher every day, with no real dips, which is what I normally see. I was testing 1st and last thing in the day. The last 4 readings were 8.0 or Hi. Which I normally never see on shorter fasts. Never seen the Hi before either, I thought it was the meter not working properly!
So, I don’t think I’ll bother much with dry fasting as it doesn’t really fit in with the way I live right now. I’m 5’10’ with a 27½” waist (66 last October) so I am ‘almost’ lean enough (but never enough, obviously). When I am regularly fasting I can still ride my bike to see friends or visit cafes and have a coffee, but with dry fasting you cant really visit a cafe and just sit there, not the ones around me anyway. So it’s a bit too socially distancing for me.
The best inspirational video I’ve seen on fasting generally is: https://youtu.be/jhE-JD6SZWM?si=Y8hthXnZWTYB-sSS It’s a presentation by Dr Matthew Phillips. He uses a Ketogenic Therapy to try and help people with incurable brain tumours, and other things. He’s a proper working clinical Neurologist and his colleagues in the same building started sending him their ‘no hopers’ patients with only months to live. 2 years later they are fine and the tumours have almost disappeared. This is a supplement to their standard of care, not a replacement. He works with the cancer specialists. He himself does a 48h fast every week and a 5 day fast once every one or two moths. The 1st section is a general introduction to keto, mitochondria, etc, The rest are patients presenting on stage telling their stories. Worth a watch!
. Was that a misprint? Wow!!!

Ha! Well spotted 
My apologies. The 66 is my age in years, not a waist size.
Writing anything online can be tricky at times 
. Yes, I misunderstood too.

Well, a 27.5 inch waist size is still great, regardless of the age, really. My pants sizes are 34 inches, which means my waist size is bigger than that.
