In different countries, different weights are normal. Like in Europe, from what I've gathered by talking to people from this site, is that a larger person, if only a little, is considered normal. I'm 163 cm and 62 kg. I don't know what this is in your system, but I think two kilograms equals a pound. Does Tina think she is overweight? If not, and she eats healthy and all, she seems normal. Did you check her BMI on the calculatopr? Because that will give you a good indication if her weight for her height and age is normal.
