If you want to lose weight, start calorie counting. It's really not that hard with the apps available now. Take an educated guess at your matianence calorie level, and eat that for a week. Weigh consistantly every day (first thing in the morning is a good bet) and at the end of the week check the results. If you're at the same weight, that is your maintainence. Then decide how much you want to cut. 10-15% calorie deficit is a good starting place. Note that a pound of fat is approx. 3500 calories so of you want to lose a pound a week, target a 500 cal deficit a day.

The importance of exercise is two fold. It is the best way to ensure that you are losing more fat than muscle (you're going to lose both in a cut, but the more you exercise the heavier the ratio will go towards fat). It also increases your maintainence, allowing you to eat more and still cut.

Beyond that, just be smart about how you use carbs. Your matianence will adjust over time and eating carbs speeds this up as it adjusts your insulin sensitivity. You will need them for fuel if you're exercising hard, but you don't want to eat them on off days.

Unless a person is overweight, which she certainly is not, this sounds like a great way to start developing an eating disorder
