I was in the same boat as you. Used to be athletic and in shape, then my new job started and I was trapped behind a desk, never moving. I lost 15 lbs. in the past month by doing a few very easy things (which is great considering optimal weght loss should be about 2 lbs per week.)

I go to the gym 5 times a week (mon-fri) take weekends off. (do at least a half an hour of cardio and do strength training 2 to 3 times a week.
I eat something healthy and small every two hours to promote metabolism (Apple, 100 calorie granola bar, etc.)
I eat two meals a day that consist of either baked chicken, broiled steak, or baked fish with some veggies. (1 serving should be some carbs, like a potato with dinner.)
I don't snack on crap!! (no chips or candy)
Don't drink soda at all!!!!!!!! (no diet soda because it's loaded with sodium that makes you do what.....drink more soda!) Drink close to a half gallon of water per day (you should never be without a bottle of water in your hand)

Follow those guidelines and I guarantee that you lose weight the healthy way and fairly quickly. I don't know how big you are now, but remember that the more fat you have on your body, the more fat you burn in a month period. So I went from 190 to 175 in a month. If you are 250, you would reach the 15 lb. mark faster than I did.

Oh ps- switch to 2% or skim milk, switch to whole grain bread and pasta, and be sure to eat breakfast everyday to fire up you metabolism.

Good Luck
