In R, why does the memory of an object as reported by `object_size()` not match the resulting `.RData` image save of the object?

I have an list object called my_list in R that is reported to occupy 53 Mb in memory, by calling out:

> format(object.size(mylist), units = "auto")
[1] "55 Mb"

However, when I save this as an .RData image, by calling out:

save(list = "mylist", file = "mylist.RData")

mylist.RData occupies 270 Mb on my hard drive. What is the discrepancy caused by?
