weight loss competition

Hey everyone, I'm 57.5 kgs (weighed today), nd I want to be 54 which is quite hard. Im 17 year old girl, My height is 5 feet 3 inches nd my bones are somehow heavy as compared to other girls with same age, height etc. So I wanted to say that I want to start a competition with anyone of u whose interested, but your weight should also be in 57 kgs like not less or more... then at the end of this month we would see who wins. And who lost how much kgs. We can also do this competition like in a group containing more than 2 girls. Who ever is interested kindly add me or message me. :) thanks!
