Without looking at your food diary it's hard to give advice but you should stick to the basics,

1. make sure you have set a realistic calorie target that you can hit
2. Eat your calorie target every day
3. Don't worry about too much about the type of food you are eating to start with just hit the target
4. You must log everything you eat, if you cheat you're only cheating yourself
5. Drink plenty of water if you can diet drinks if you don't like water, always avoid using your calories in drinks if possible.
6. Be patient it's a marathon not a sprint.

Good luck, add me if you want I'm uk based and I log on everyday
