Mindy,
In my experience, losing weight really does boil down to calories in vs. calories out. The type of calories matter in terms of health, energy, and an overall feeling of well-being but you'll lose weight as long as you burn more calories than you consume (regardless of where those calories come from).
There are many formulas to be found but I've always used the basic "body weight x 13" (use 14 if you are very active) as a way of calculating how many calories I need to maintain and then subtracted 500 to 1000 calories from that number in order to lose. Honestly, though, there are so many variables to losing weight, specifically how active I am at any given time. So, I'm not implying that is the most accurate way to determine what you need but rather that it has been an accurate enough platform to begin with as I tried to determine exactly how many calories I needed through trial and error.
