How far away do yu live from work? On nice days, you could bike ride to work, which would help alot. Walking and riding instead of using your cars for short errands helps too, and is better for the car too.
Down hill skiing upwards of 20-30 days a year makes a huge difference over the winter.
And lastly don't eat anything out of a box at all. Fresh vegetables, good meat or fish. No chips, less beer, and when you want to snack, carrots, celery, etc.
Do ths, and limit your caloric intake to about 1500 a day and you'll loose some weight. Good luck. Nice side effect, you will feel alot better when you stop eating processed and junk food! The vegetable take some getting used to, but after a while you'll like them.
