I am a stepmom to a 20 year old college student, a young woman. I married her father 3 years ago. I've known her since she was 12. She has always struggled with her weight, she is an obese girl who is very much into junk food. Her own mother does not mind, she says "she is beautiful as she is." And she really is beautiful. But she can't go up one flight of stairs without being out of breath, she struggles walking, she complains that she can never find clothes she likes.
I like her, she is a nice girl, she is polite and sweet. But my heart breaks when I see struggling her like that and everyone just keeps quiet, so that they don't hurt her feelings. Can I do something? Her self-esteem is down low

Her father is concerned too but doesn't want a potential confrontation.
