You do realize some people are just petite, right?

Exactly!

Exactly. Its sad to see that some people just cant understand that.

Some people are naturally slight, and some people have physical conditions that make them lose weight. But since actresses are under constant pressure to keep their weight very low, and they wouldn't be insurable or employable if they had a serious physical illness, Occam's Razor tells us that an eating disorder is the likeliest explanation for an actress becoming seriously underweight.

Instead of just moderately underweight, which is a condition of employment for most of them.
