i didn't read any of the previous posts but this is what i do. Drink as much water as possible, water will fill you up and it will regulate you to smaller meals.
When you work out, do weights then immediately go to the cardio. I usually do 45 mins of weights then hop on the elliptical/bike (i have a bad knee or i would run) and do intervals for 25 mins, warm up 5 mins, then do 4 intervals, sprint 100% 1 minute and go 60% for 3 minutes.
