I am looking to loose weight.?

I am 17 years old and looking to loose weight. I run/walk 2 miles a day. And do 25 push ups morning and night. I just ate 1000 calories of taco bell. And I havent done my running/walking today. Do you think I would be able to burn some of that off? I weigh 220 LBS. but its not like a chubby fat. Just a wide frame. Just on the heavier side.
