I don't contest that ketone level affects weightloss, but just to be clear, ketone pee strips don't tell you anything about your "ketone levels". They tell you the concentration of ketones expelled in your urine, which varies by a lot of things, like time of day and hydration levels.

Precision Xtra test strips will give you a far more precise and accurate measure of ketones in your blood and if you wanted to do anything quantitative like in this case study, you'd want to use those.

Hmm I don't think you're right. I'm looking at an old bottle of ketostix brand, and it specifies Acetoacetic Acid, which seems to be some kind of ketone. Or maybe it's another byproduct?

Edit - Also, presumably the other factors like hydration and time of day could be tracked as well used to apply learning

you're correct; had my terms jumbled. edited my comment for correctness.
