Measuring ketones

[Philip1943]

Some people following the ketogenic diet keep track of their ketones by measuring betahydroxy butyrate in ther blood ie BHOB. This method is accurate but a bit expensive. Over the last few years there has become available breathylisers that measure acetone as an indicator of the degree of ketosis.

Does anybody here use this latter method ? and if so, would they be willing to share here their results/experiences.?
