Did you notice the most popular word to describe her? It's "svelte." Here's a little "Google" search to show you how many times it's been used.
This is how fame works. If you go from a size 18 to a size 10, you are svelte. Yea you!
However, if you go from a size 4 to a 10, you are not svelte. Boo. You are now an enormous cow who must be destroyed. Also, the only photos that magazines will run of you now are of you eating. The horror! How dare you eat in public? Have you no self control, Jessica Christina Simpson Aguilera?
Fame is stupid.
