Weight loss will be much tougher now than it was before, but still very possible.
First off, do the little things. Walk/bike instead of driving. Take the stairs. So simple but they make a huge difference.

Eliminate all unhealthy food from your house and don't bring money to work, pack your lunch. This way you won't be tempted to go buy a snack. Drink water when you are hungry, hunger can be eliminated with a glass of water. Also, you can brush you teeth when your hungry.

At this point you will need to start using weights (if you haven't already). This will tone your body. Don't be alarmed if you don't lose a lot of weight (since muscle weighs more than fat) you will look and feel better. My advice get a personal trainer.

Do cardio (walking, jogging, biking) at least 3 times a week and for more than 20 minutes ( I would suggest 40-60mins). If you work out for less than 20 minutes your body will not acknowledge that you have worked out. You also have to increase the intensity and duration as you progress. If you run 20 minutes at the same pace for 3 weeks, you are not going to lose weight...this will only help you maintain your current weight. You always have to increase intensity and duration if you want to notice a difference.

Hope this helps.
