"Picky eating" is not going to help. I agree with Kathy that you should log your daily food to get an idea of what you're eating - and you have to be honest about it, put in every morsel that goes into your mouth!
Upping water intake and cutting out things like soda, beer and/or other sugary drinks may help you quickly lose some "water weight" (a few pounds in a few days), but that will come right back if your diet consists mostly of junk foods.
Try to find some healthy foods that you like to eat and add more of them to your daily food intake. Chicken breast is a good low-cal, high-protein food, but not if you're eating it with lots of bad sides. Keep trying foods, and don't be put off by new foods!
Portion control is also helpful. Read how much a serving of your foods actually is, it might be less than you think!
