How to interpret the values (in the Ketonix App).

Here is a description of how values could be interpreted by a healthy normal person.

If you get values in the green range, you are in nutritional ketosis. This means you eat low carb and use fat as fuel (for some this nutritional ketosis also cause weight loss). This range indicates maintenance ketogenic lifestyle.

Values in the yellow range commonly is associated with caloric deficit combined with a ketogenic diet. The caloric deficit could be caused by exercise or intermittent fasting (or a combination thereof). Having values in this range (or above) is likely causing weight-loss. Getting into this range normally requires you to lower your glycogen stores. Depending on your tool to do this (exercise or fasting or both) and your current glycogen storage, it could take more or less time. 

Values in the red range (and above) indicates very high ketosis. People without diabetes or other metabolic disease will reach this range occasionally. If you have diabetes of any type, you should definitely check your blood glucose. People having diabetes should regularly check their blood sugar.


Testing when not using a low carb/ketogenic diet

If you follow a high carb diet and want to track your ketones, we suggest you track them in the morning before breakfast.  High carb meals could for some create methane gas from bacterias breaking down carbs. Testing in the morning before breakfast would have the least effect on your breath ketones. A large glas of cold water before testing is adviced.

Our mission is to provide a simple, cost effective and painless method to know if your body is in ketosis and the strength of it. With the insight of your level of ketosis you could adjust your actions to increase/maintain your ketosis.

Ketosis is when your insulin levels are low and your liver starts to metabolize fat into ketone energy. When ketones fuel our brain we sense a high mental clarity and energy boost. Without the ability to get into ketosis when glucose and glycogen is low the human man kind would not exist.

Ketosis is not the the same condition as Ketoacidosis. Ketoacidosis is is a complication of type 1 diabetes mellitus. It's a life-threatening condition resulting from dangerously high levels of ketones and blood sugar


Ketonix® analyze your breath for the ketone named Acetone. Acetone is spontaneously released from the liver when ketone energy is formed.

The more fat that is mobilized into energy, the more Acetone in your breath.

Don't mixup breath ketones with blood ketones. Blood ketones are formed from excess ketone energy and could be converted back into energy at any time. In some situations one could say that they correlate, higher breath ketone level and you might find more blood ketones. Then add that your body could have issues both creating them and use them for energy, these factors makes it harder to interpret blood ketones. This is one of the reasons Ketonix® was invented, to indicate the strength of ketosis.
