Exogenous ketones and IV dextrose were proposed as alternative intravenous solutions to standard glucose-based solutions, with lactated ringers considered ideal.

“there was one other thing that you were proposing that I thought in the theory made sense but I just thought there's no way they're gonna go for it which is just using exogenous ketones as well throughout oh and the other thing that you wanted which I again completely agreed with IV exactly I know dextrose instead of dextrous yes no dextrose and I'm like also because we'd be such a shock to my system because I'm already a no-carb person for you know two years and now I'm under the stress and now they're jamming a bunch of sugar into me that can't be good and I agreed with Jack on this that you know lactated ringers would have been the perfect intravenous solution and you could happily go days without glucose”
