I look at it just the opposite. Alcohol, in too much quantity, is essentially poisonous to your body, so it processes it out first. Glucose, in too much quantity, is also poisonous to your body, so it processes it out second. Ketones, on the other hand, are
produced[1] by the body, so can stick around as needed.
1. Trust me, I know everything produced by the body is not good. It's just that, when comparing ketones to glucose and alcohol, I think ketones win hands down.
