About the 40 kg. I did the math with a BMI of 19, which seems to be the minimum. Below that you are underweight. And this is already quite thin.
I calculated 1,45 m, which is 4.76 feet.
Looking at the picture on page 11, where she is almost one head smaller and considering she is Japanese, this height might be possible.
In general this fomula might give you some help, you also have to consider muscle mass etc. If you visit the gym, then you will have to calcuate this in. The BMI might say you are already overweight, but because you have 5 kg more muscles than someone your same bodystructure and height, you cant use this formula anymore.
Just use a mirror then. :D
