Sounds just like me four months ago. First thing is that you have to want to change your eating habits. I recommend Its done wonders for me. I've been able to drop five pounds in 4 weeks using this site, but they also teach you how to live a healthy lifestyle.
I also recommend the book, "Eat this Not That". It has the premise that we all eat out, but when you do, make the right choice.
For example, I love BK Whoppers with a Million Calories, but now I choose a Whopper, Jr. and you save lots of calories just by making a better choice.
