Hi Krista and WELCOME!
You've come to the right place - this is a fabulously supportive site!!
Those lunches out every day will do in any diet, for sure! You've tried all the fads, so you KNOW they don't work - so a good place to start might be
www.fitday.com which will help you journal everything you eat. You can also put exercise in - it's a good way to keep an eye on what goes into your mouth - LOL!
Set realistic, attainable goals, and just keep at it!
Keep coming back and tell us how you're doing and what eating plan you are following, even if you devise your own!
Good luck -
Heather
