Using Ketone Breath Analysers

Using Ketone Breath Analysers – Michel Lundell and Alison Gannett4.3 out of 5 stars5 star65%4 star23%3 star0%2 star3%1 star7%26 ratings2620:51

Michel Lundell managed to get his epilepsy under control using a ketogenic diet (this is now an accepted and proven treatment).

To make it easier to track his ketone levels – and being an engineer – he then developed the first ketone breath analyser, called the Ketonix.

In this short talk from Low Carb Vail he tells his story, and describes different ways of tracking ketone levels in the body.

After that Alison Gannet talks about being diagnosed with a massive malignant brain tumor in 2013. She had surgery to remove it and has then used a ketogenic diet to hopefully reduce the risk of relapse – so far so good. Here she talks about her journey, including tips and tricks for how to stay in optimal ketosis.

What would happen if you spent a year eating a very low-carb diet, a ketogenic diet, while tracking all kinds of blood tests and other things?

Dr. Jim McCarter did just that and presented his findings at the recent Low Carb Vail conference in this 10 minute talk. The complete presentation is now available on our member site:

The First Disposable Breath Ketone Test Has Arrived

The Metron breath ketone test

Do you want a simple way to check for ketosis, without a urine or blood test? It’s also possible to check you breath for ketones (acetone). This has already been possible for some time with the Ketonix reusable breath analyser (costing $149).

Now the Ketonix is joined by the just-launched disposable test Metron, which can be ordered via Amazon ($28 for 10 tests).

Metron is cheaper if you only want to do a few tests (up to 50 tests), but the reusable Ketonix is cheaper if you want to do more tests than that – testing is free once you have one.

At some point we may do a test of Ketonix vs. Metron. Would you find that interesting? Or do you already have your own experience comparing these two devices? Please leave a comment.

How a Diet Change Can Free People from Epilepsy

Can you cure your epilepsy without medication? Yes, this seems possible for many. At least you can keep the disease in remission long term with a change in lifestyle – without the need for strong drugs or their side effects.

Here’s Michel Lundell’s story:

Happy Ketones


Here’s low-carb blogger Jimmy Moore at the recent obesity conference. He’s smiling about soon hitting two consecutive years in deep ketosis (and 80 pounds or so lost).

The gadget he’s holding up is a new breath analyzer for acetone (i.e one of the two main ketone bodies). Yellow light means plenty of acetone.

The gadget is $99 and is good for any number of measurements. It seems to work pretty well. Better than urine strips but not quite as good as the gold standard: blood measurements.

You can read more about the Ketonix breath analyzer and order it here.

Final Report: Two Months of Strict LCHF and Ketone Monitoring

Note: This experiment was done six months ago and initially only reported on my Swedish blog. This is a somewhat delayed translation!


What happens if you hugely digress from a low-carbohydrate diet and suddenly eat a whole load of carbs?

Here is my final report following two months of a very strict LCHF diet, and daily measurements of four parameters:

  • Blood ketones (the red curve)
  • Urine ketones (yellow)
  • Weight (purple)
  • Waistline (purple)

To get familiar with the experiment design, I recommend reading my first report. For results from the first month, have a look at my second report. Here’s the third and final one, discussing the second month.

As you can see from the above graph, I took the opportunity to conduct a side experiment. The pink vertical column marks one weekend where I conciously completely deviated from the low-carbohydrate diet. I was on the Swedish archipelago “Koster” for the year’s lobster premiere, and simply had the same food as everyone else.

So, what happens if you totally veer off the low carb lifestyle after a long period of strict LCHF? Is complete havoc wrought in your body? Do you have to start from scratch again? Here’s the answer: Continue Reading →


Four Weeks of Strict LCHF and Ketone Monitoring

Can ketone measurement help you lose weight and improve performance? That’s the main question I’ll be trying to answer with my four-week experiment.

See Report #1 for diet and experiment design.

Note: This experiment was done six months ago and initially only reported on my Swedish blog. This is a somewhat delayed translation!

Below are graphs of my weight and waistline over this first four-week period, as well as the results of blood and urine ketone measurements.


After two to three weeks of light nutritional ketosis, I’ve now spent 8 days in “optimal ketosis” – that is, between 1.5 – 3 mmol/L. Want to know what’s happened?

Lose Weight by Achieving Optimal Ketosis

Do you want to lose weight? Here’s number 16 of my 18 best tips. All of the published tips can be found on the How to Lose Weight page.

Before we get started, here’s a short recap of the tips so far: The first and most crucial piece of advice was to choose a low-carb diet. The next were eating when hungry, eating real food, eating only when hungry, measuring progress wisely, being persistent, avoiding fruit, beer and artificial sweeteners, review your medications, stressing less and sleeping more, eating less dairy and nut products, stocking up on vitamins and minerals, using intermittent fasting and finally, exercising smart.

This is number sixteen:

16. Get into optimal ketosis

Warning: Not recommended for type 1 diabetics, see below.


We’ve now arrived at tip number 16. If you’re still having trouble losing weight, despite following the 15 pieces of advice listed above, it might be a good idea to bring out the heavy artillery: optimal ketosis. Many people stalling at weight plateaus while on a low carb diet have found optimal ketosis helpful. It’s what can melt the fat off once again.

So how does this work? A quick run-through: The first tip was to eat low carb. This is because a low-carb diet lowers your levels of the fat-storing hormone insulin, allowing your fat deposits to shrink and release their stored energy. This tends to cause you to want to consume less calories than you expend – without hunger – and lose weight. Several of the tips mentioned above are about fine-tuning your diet to better this effect.

Is Pepsi Max Bad For Your Weight?

The Pepsi Max Test

Can artificial sweeteners from diet sodas affect your weight? My six hour experiment the other day implies that the answer might be yes.

The results can be seen above. I drank the Pepsi Max (17 oz.) after about an hour. The black line is the blood sugar and the purple line is the ketones. Continue Reading →
