Just a few random tips:
I like to add lots of fresh fruits and veggies into my
diet instead of prepackaged snacks.
Move as much as possible - pace while talking on the phone, walk anywhere that is less than 1/2 mile away (increase this over time), walk around the house during commercials, etc.
Record EVERYTHING you eat - check out the sites mal posted.
Always carry snacks with you in case you get hungry so you won't be stuck getting fast food, vending machine snacks, etc.
