College Student's Weight Loss Plea?

So I come back from college and I jump on the scale: "Woah, 14lbs heavier? No way!" But it's true, I gained the freshman unfortunate. Currently I'm trying to lose the weight, the healthy way. I've cut back on my calories, eating fiber rich/protien rich/low fat/low sugar/lots of fruits and veggies/ kind of foods, with proper rations and so I ingest about, oh 700 -1200 calories per day depending on the foods I eat. I also exercise, about 15 min of cardio and some weight training/ aerobic cles 6 days out of the week (1 -1/2 hours per work out session), minus sunday. I've noticed some muscle definition, but hardly any weight loss and very minimal "inches" lost, if any (I measure). I'm wondering what I'm doing wrong and why my body persists to stay in this homeostasis state. I know for sure I've gained muscle, but I really haven't lost any fat yet. It's been about 2 - 2.5 weeks into my training and frankly, I'm getting a little frustrated with the results. Any advice that may help?
