if i eat well can being underweight be bad??

[Adrianna Gabriella j]

hi board.

I'm 164cm and weigh 45kg, apparently this is too low. That said I eat heaps of veggies, grains, nuts, meats, dairy and treat foods. basically.. my diet is a-ok so do I *need* to gain weight? I don't understand :I ..

thanks :dizzy: advice would be hugely appreciated..
