10 Best Ketone Meters to Buy in 2022

best ketone meters to buy

Staying on track with your goals on the keto diet becomes easier with the right tools. One of the most useful forms of feedback is the ketone meter. A ketone meter measures ketone levels in your blood or breath to determine whether you are or aren’t in ketosis.

Blood ketone meters detect beta-hydroxybutyrate (BHB), the most prevalent ketone body that circulates through your bloodstream. Breath ketone meters, on the other hand, detect acetone (Ace), which is the third and least abundant ketone body (1).

Testing for the presence of ketones is beneficial especially if you’re just starting a keto diet, although you can also rely on keto flu symptoms like fatigue, headache, muscle cramps, bad breath, and weight loss.
