If you go to your local drug store you can purshase KETOSTIX which can monitor you ketones
I am burning high ketones and have been doing so since I have come back to atkins
I was amazed at the level
It also warns me if they are dropping a bit that I better smarten up and go thru my daily diet to see what I have aten different to make it drop a bit
they cost around 8 bucks for a jar of 50 here in canada where I am
and they are at the counter not on the shelf
the higher the colour the more ketones you are using
