In normal healthy individuals, BrAce can range from 0.5 to 2.0 ppm. Adults on ketogenic diets (e.g., high fat with low carbohydrate) can have elevated levels of up to ∼40 ppm.
The article includes a graph which has the same data:
This actually correlates to what I measured with my Ketonix. I got numbers from 4 (in Ketosis) to 22 (when fasted 10 days).
That correlates to the scale above which shows a Ketogenic Diet in an adult to go from 2 to about 40.
The problem is that the middle of this Ketogenic Diet scale is 10. It took me several days of fasting to get to this level. So for normal Ketogenic dieting there’s not enough scale to blink the colored LEDs on the unit. If you look at the fasting scale you can see I never reached the higher levels I should have been seeing at 10 days into a fast.
Seems like the unit sort of works and sort of doesn’t work. If it is accurate for PPM then I would never see a number above 50% if I was at the very top of the Ketogenic diet scale – which is not realistic.
Here are my blood glucose numbers over the past three months. I have been fasting the last week so the number are lower during the fast. This is an average of 113, and a HbA1c of 5.7. The normal range for level for hemoglobin A1c is less than 6%. Note that I am still taking Metformin. I am also doing High Carb, Healthy Fats plus Intermittent Fasting.
It has been seven months and I am still doing well on this diet.
Total weight loss has been almost 70 lbs. Weight loss is slower now but I’ve either been dropping or steady for the past couple of months. My goal weight is still 50 lbs or so away.
Nuts seem to be my weakness. I can eat a 10 oz container of Macadamia nuts (at 2200 calories) and still want more. I have managed to stay keto every day for the past 7 months with no cheat days. I know what would happen if I cheat.
I have not been bike riding since I got the new trainer three months ago. I have done zero exercise but I have been a lot more active since I am so much lighter. I am considering starting to ride the trainer to get ready for the summer.
I hired a housekeeper to do a deep cleaning but have been able to keep the house cleaner generally now since I have more energy.
Blood sugar numbers have been great as well. Still taking Metformin (when not extended fasting). Blood sugar numbers have been in the 100-110 range except in the early morning when they are typically about 10 points higher.
I still do OMAD (One Meal a Day) intermittent fasting.
I am going to start another extended fast today. Last two were 10 and 9 days. I’d like to make it another 10 days this time.
I started a new fast on Sunday so I am at day 4 now. So far it is going very well. Not very hungry and not too grouchy (that I can tell). I’ve dropped off half the weight I regained over the four days of eating.
Stopped taking Metformin on the third day of this fast. My blood sugar numbers are up a bit but still on the low end. By dinner time last night my Blood Sugar was 88.
Considering starting up some exercise. Not for weight loss, it might in fact hinder some weight loss. More to work on my Blood Pressure. I have had a nice mountain bike since 2007 but I rarely ever ride the bike. So I bought a trainer which is attaches to the rear tire and turns the bike into a stationary bike.
One of my Keto/fasting heros, Tom, uses an ap called Kinomap. It lets you ride in different places in the world where people have recorded videos of their rides.
I pulled the bike out of the basement, cleaned it off and pumped up the tires. Hopefully I will be in riding shape by Spring. There’s a great bike trail very near to here,
