Probably not relevant to humans as we evolved eating WAY more fat than mice did.
This may not be true.
Meat consumption certainly played a role in human development -- there's no denying that -- but there's evidence that humans may have evolved eating a mostly vegetarian diet. Compared to mice -- some species of mice anyhow -- who regularly eat various species of insects, worms, and the remains of larger species, it's legitimately possible that mice evolved eating significantly more fat (as a percentage of their size) than humans.
See page 34-35
looking at the plant to animal proportion of 229 hunter gatherer societies the mean animal consumption was 68%. And there were 0% vegetarian societies, all were omnivore.
