Supper is the meal where you burn the least fat, while breakfast is the one where you burn the most. Try to change that part of your diet.
This is the answer to all your overweight problems:
CARDIO!
You gotta run, make a warm-up of about fifteen minutes covering all the stretchings you can imagine. After that I would suggest running 1 1/2 miles and then make small sprints, 100 meters you run at top speed, 200 meters you walk. Repeat this running and walking process for a mile.
After that make a cool-down and if you still feel you're up to it go and swim some laps on a pool.
This is a mid-explosive cardio workout, you must feed yourself with protein and carbs before and after you do the routine. If you feel it's too much for you reduce the workout by half.
Also drink at least 2 L of water. Helps remove waste.
