I have been a 50 kgs for the past 15 years tried eating all types of food to put on weight noyhing happens.?

I'm assuming that you're wondering why you're not gaining weight. There are a number of factors to this question. Could it be that your metabolism rate is high that it burns off calories quickly to the point that you don't even notice t hat there was a weight gain, or maybe genetics has it where your body is designed to be 50kg at it's maximum weight. Have you tried protein shakes to add a few extra pounds onto your body mass. By all means love the body that you're in and no matter what size you are just be thankful that you're alive.
