I'd recommend not worrying as much about your weight and focusing more on your athletic performance.
Find your limits and then try to beat your personal bests. Sprinting, distance running, vertical leap, pull ups, curls, squats, etc.
If you do this, and cut out processed foods, you'll be feeling great and you'll more than likely lose weight in the process.
Cutting out processed foods means don't eat things that come in a box. No instant foods, no artificial flavours, no added sugars. Instead, add fiber, leafy greens, nuts, and lots of beans.
With a little discipline, it can't fail.
