What is a healthy weight for someone who is 5'2?

If you are muscular or built like a gymnast, its quite likely to be fit in a weight range from 45-60 Kg. However, only a doctor or a nutritionist can look at you and decide your body weight spread out properly and tell you if you are fit or not. At 55Kg, you could have skinny hands, feet, shoulders and nice belly--- so take your measurements- chest, stomach,waist, hips and try and ensure they are in reasonable proportion.
