First off, we need to understand what ketostix actually measure, and more importantly, what they don’t. Generally speaking, ketostix measure excess ketones in your urine. They are considered excess, because they are removed from your serum and shunted to your urine by your kidneys. Their caloric content is thereby wasted.
Of the three types of ketones (acetate, acetoacetate, and beta-hydroxybutyrate) produced by your body, ketostix only measure acetoacetate.

This is extremely important to understand, because it turns out that your body produces different quantities of these different types of ketones depending on how long you’ve been in ketosis. If you’ve been in ketosis for a while, you’re going to see a reduction in the “intensity” of what you register on your ketostix for two reasons:

A change in the relative volume of the ketones produced/present in your body
A reduction in the volume of ketones in your urine as your kidneys reduce the amount they secrete
