Went through this myself a couple of years back.
I'm still a little pudgy (hovering about 215 - 220 at 6'2") but I have been doing the following.
(most of which has already been said)
1. say bye to sodas. I lost ~8 pounds just by doing this.
2. Sugary snack food - it's not gone but is cut way back.
3. Fried food should be cut way back too. Hard to do in Texas, I know.
(I swear they would fry a salad if they could)
4. I walk about 5 miles a day (knees can't handle running).
The more than 20 mins consecutive of cardio mentioned elsewhere is where you really start burning the fat.
5. If you feel the need for seconds, give it a couple of minutes. I've found I really don't need them.
