I have a question for those who measure ketones. From my research I get conflicting information.

Some people say when you measure ketones you want high levels.

Others say you want small level, and if you show high levels it means you are spilling ketones. Those are unused ketones, meaning you are consuming too much fat and need to lower your intake to force the body to use the storage.

I get the best information here so I thought I would ask.
