Welcome to r/science! This is a heavily moderated subreddit in order to keep the discussion on science. However, we recognize that many people want to discuss how they feel the research relates to their own personal lives, so to give people a space to do that, personal anecdotes are now allowed as responses to this comment. Any anecdotal comments elsewhere in the discussion will continue to be removed and our normal comment rules still apply to other comments.

Translating from just the title: “putting ketones into your body prevents new fat from being made and prevents insulin resistance from being built” which is interesting because it means that it isn’t necessarily the breakdown OF fat that prevents new fat from being made, but merely the presence of the resulting ketones.

Regrettably (as far as I understand) this is true for all except the brain, which loves glucose so much that, even when in ketosis, it will tell the body to break down proteins and muscles to get glucose to function.

Ah yes, another nice non biased article from "Meatrition"

This is a very complex methodology, but here's what I understood from this paper.

They enrolled 8 healthy males between 22-35 years of age with a normal BMI.

Gave everyone a Growth Hormone infusion.

Then one-half of the subjects got Ketones (betaOHB) and the other half got saline (control group) as an intravenous infusion. There were 2 visits a month apart and each person got a chance to be in each group (that's the crossover design).

Growth Hormone increases Free Fatty Acids (FFA) in your body by breaking down fat (lipolysis), but if a participant was in the Ketone infusion group, their serum FFA became markedly lower during betaOHB (Ketone) infusion even after getting the Growth Hormone. The study found that Ketones block the breakdown of fat through binding to HCA2 receptor.

During the betaOHB infusion, lots of Ketones entered the skeletal muscle tissue and promoted glucose uptake, which increases insulin sensitivity in the skeletal muscle. Also the betaOHB that entered the skeletal muscle was immediately converted to Acetoacetate and entered Krebs Cycle.

Bottomline: Having extra ketones promotes uptake of glucose by muscle, which lowers your blood glucose level and improves your insulin sensitivity.
