I have to agree with the water and snacking. Those two things help you avoid a food binge which seems to be a real issue. Also, the more you cook and prepare food for yourself, the better you will tend to eat since you'll probably end up with less sodium, more nutritious food and a more well-thought out meal. You don't have to do it for every meal, but just building up a know-how of a few different foods will help a lot.
Apart from dedicated exercise time, being lightly active in your daily life can help a lot too. Get up and walk around more if you sit at work all day, take the stairs, etc. No need for a radical change in your life since that's not likely to be sustained over time.
