Weight loss tips for teenager HELP? -

OK, now i am 14 years old and i\ am about 160 ish and weigh around 50kg. Now i have a little gut and i want abs showing. I can feel them but cannot see them. I have been cutting down on food, eating fruits as an alternative rather than chips. I have been running around 5 kilometers and doing 3 sets of as many push ups i can and sit ups.I am mainly more concerned for losing around 3kilograms and showing abs. Am i doing everything right? Any more tips would be appreciated.
