My friend is rapidly losing weight and I’m very concerned about her. How should I confront her?

Can you answer Josie S.’s question about Weight Loss?:

My friend has been losing a lot of weight this past year, and I’m very concerned about her. She is 14, 5′ 7” and 110 lbs. She is still losing weight, but I don’t know how to confront her because she is not a trusting person and wouldn’t tell anyone if she had a problem. How do I help her without making her feel like she’s being put on the spot?
