There's an study from the 60s where obese people were fasted for weeks on end, and then supplemented with small amounts of glucose. As little as 8.5 grams was enough to make their urine ketones go from large to very low. Although urine ketones pretty much disappeared, blood ketones remained just as high as they were without the glucose supplement. That bit of glucose spared just about the amount of protein that would have been needed to synthesize that amount of glucose. This is an example of a situation where it's easy to argue that a decrease in urine ketones was not only not harmful, but probably beneficial. The kidneys regulate urine ph balance, when ammonia, which is alkaline, is being spilled as a byproduct of gluconeogenesis in the kidneys, they may allow more acids, such as ketones, to also spill.
