Hey Destiny -

The forums the others pointed you toward are good...check them out!
If you have limited resources, my favorite plan is a basic calorie-reduced plan. Just set a calorie level, count what you're eating using free websites like FitDay.com (my favorite), SparkPeople, The Daily Plate, or many others, focus on getting mostly whole foods (whole grains if your body responds well to them, veggies, fruits, lean proteins, etc), and get some exercise. Simple and takes nothing more, at it's simplest, than the internet and some measuring cups.
The great thing about calorie counting is that you can estimate for cafeteria food and really any other situation, and work almost ANYTHING into your plan with a little planning and effort.
If you want more info about that, we've got a GREAT Calorie Counters forum. You might want to read there, particularly to get a number on where to start...with all that exercise, finding a good calorie level for you might be a little tricky, but there are a ton of free calculators out there on the web to give you a starting point.
So look around, jump in, and get to posting. And I can't wait to hear more from you soon!
