Kill your appetite, and if you aren't hungry for dinner, don't eat it. You won't make it to bedtime without eating anything else, but another snack a little later shouldn't come anywhere near the amount you'd have eaten at a full meal. Not only that, you've evened out your blood sugar swings, which can take your food cravings down even more. It's important to make sure you aren't sabotaging your own goals without even knowing it. Take a good look at anything you swallow that could slow your weight loss.
Bookstores have all sorts of literature on that kind of stuff now.
Mood-enhancing drugs and still other types can also be involved, so check them all. It's worth having a better idea what you're swallowing in any case. Many medications are well sweetened to make it easier to get them down. Make sure you really need the product you're taking, and that you're not getting into a habit because they taste good. Beware of small candies, especially ones that dissolve in the mouth.
