For starter's I'd start working out your legs. Being the biggest muscle in your body makes them the most efficient at burning calories, so increase them would help a great deal.

Remember you can't spot reduce fat, generally the fat that disapears first are the youngest fat cells on your body.

Obtain nutritional information on your foods, look out for saturated and trans fats.
Don't eat after about 8 at night.
Make sure you have a big breakfast.
Try to eat smaller meals but more often, it helps keep a steady metabilsm.
If you can reduce alcohol in take.
If you mix milk with your protein shakles try a low fat milk
Instead of eating normal pasta's try brown ones.
Cardio
Cut back on junk food.

Honestly dude I could go on for ever. Just remember losing weight isn't about dieting it's about life style. Make a few of these key lifestyle changes and you should lose weight.
