I used to be a little on the heavy side for my height.. I was 5'8" and about 180-190 lbs and now i'm about 5'10" and 145lbs. All I did was stop drinking so much soda(this means drinking diet if you do drink it) or I drank iced tea, I cut my meal portions down, and made sure if I DID snack.. I ate healthy snacks like apples or bananas. Also another thing you can do if you get the urge to eat is drink a big glass of water.. It will fill you up and it will pass enough time for you to make it to your next meal. Just watch what you eat from now on, you'll notice yourself losing weight slowly and you'll feel alot better about yourself when you know you're losing it. I did absolutely no excercising while I lost all that weight so it can be done. Now that i'm basically all skin and bones, i'm trying to put some muscle weight back on.. lol.
