The cellphone app syncs easily and the breath acetone numbers results are easy to see how deep into ketosis you might or might not be. This device will need to be sent to Sentech for maintenance after 320 uses at an additional cost at that time.

Frequently Asked Questions
I know you were looking for what are the best options, but here is some more detail as to why we might need a good meter to measure ketone levels to help us easily know if we are in ketosis or not.
What Is the Most Accurate Ketone Meter?
Blood ketone meters are still the gold standard tool that is best for testing overall nutritional ketosis.
Blood ketone measurements are used to assess ketoacidosis in when concerned about diabetic ketoacidosis and are more accurate than urine ketone testing strips and breath meters for this purpose. (ref)
Breath ketone meters are still being assessed if they are better to use than blood ketone meters for level of nutritional ketosis when testing for regularly.
They are a good option if cost of buying many blood testing strips or not wanting to prick your fingers is a problem for you.
What Should Blood Ketone Levels Be for Weight Loss?
Below are the different ketone ranges related to helping guide weight loss:
- Below 0.5 mmol/L – not ketosis, so little fat burning
- 0.5 – 1.5 mmol/L – is light nutritional ketosis for some weight loss
- 1.5 – 3.0 mmol/L – is optimal ketosis for maximum weight loss
- Over 3.0 mmol/L – is unnecessary & could be dangerous and especially for diabetics
Optimal ketosis is a good option for those who have plateaued in their weight loss efforts. It involves forcing your body to burn fat (or ketones) as an energy source rather than glucose, or carbs. To do this, you have to eat a low-carb high-fat (LCHF) diet to increase your ketone production and lower your insulin production. (ref)
What Are the Best Times to Test Blood Ketones?
- For most accurate ketones levels, test in the early morning on waking, before eating or drinking
- Test around noon, before eating lunch
- Test in the evening, before eating dinner
- You can also test in increments after meals if you’re curious to see what impact food has on your results
It is important to test your ketones based on when it is convenient for you, so you will be able to keep a routine. (ref & ref)
