How much weight would I loose if I played soccer and karate?

I am a 14 year old male and I weigh 175 and I was really wanting to loose some weight and Im going to play soccer and do karate so im hoping that that will help a lot.|||well when I did track I ran about a mil a day and in three weeks I lost 20 pounds and soccer runs a lot more so yeah it will help but the key is to drink water not gatorade or powerade or soda at all and u will see improvments|||That will help. Don%26#039;t forget to diet and eat healthy!!!
