50kg is only 110lbs, giving a BMI of only 16.5, surely underweight even for
a teenager. If she ate normally & stayed @ that weight, it could be OK but
the OP also says:
"She doesn't even feel hungry. She usually drinks only a glass of juice a
day and that's it. On a good day,
she'll have a peice of toast in the morning."
Surely that can't be normal at any age, sounds like she suffers from some
form of anorexia.

If the girl in question was 15, she would be within the ideal range
interval of 5-85% percentile (just above the bottom 5% by BMI). If she
was 14, she would be comfortably in that interval. I have no idea how
old she is, so, I cannot say for sure if she is or is not underweight.
Teenagers grow tall quickly and can become rather thin for some time,
hence the lower ideal weight range.
BMI also is a mathematically wrong index, because it uses a square of
height instead of the cube, so, very small children have super small
BMIs even though they could be quite chubby. For example, a 4 year old
with the BMI of 20 would be a very obese child, way off the charts in
weight. It is not as important for adults, who differ in height by
a few dozen percents, but it is very important for children, who are
several times smaller than adults.
