The Study and Coach function is free for all healthcare professionals that want a easy way to follow their clients progress using a ketogenic diet.

A doctor, nutritionist could with one click create their own "study". The "study" is a group of clients that one wants to access their logged breath acetone and other data points like nutrients and exercise.


It works like this:

First the doctor/dietitian/nutritionist/coach selects Create Study, then choose a name which identifies the group of clients who is targeted.

The result is a pair of keys, one is the Study Id the other is a Study Key. There is also a third key generated, the Resign Key. The Resign Key is only available to the clients on request to stop participating in the study.

The two first keys, Study Id and Study Key is distributed to the clients that would participating in the study. By entering the keys in the enrolment form, the clients are enrolled to the study.

Now the doctor/dietitian/nutritionist/coach can in one click download the data files for the enrolled clients. To view and analyse the data is as simple as dropping them on the KetonixViewer app. More advanced users might use their own spreadsheet functionality for analyse.

If this sounds interesting, please contact and we can guide you through how to set this up to coach your clients.

 We also have a startup package deal for medical healthcare professionals, contact for a quote.

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.
