Dude, what the fuck? I didn't think someone needed to come out and straight up tell you not to eat 1300 calories, but apparently that's the case. You're doing the classic failure diet. You'll lose a bit of weight, quit because you were starving yourself, and then when you go back to a reasonable or normal diet you'll gain the weight plus a few extra because you fucked your metabolism up.
Seriously, stop right now. Go back to your normal diet for a week, and then try again. This time, figure out your TDEE calories (BMR + activities) and eat no LESS than 500 below that number. That means don't go eating 500 below and then take up running and burning another 500 calories. It means take what you actually do and eat 500 below that.
That will let you lose 1 pound a week. If you're not losing that much after 2 weeks, adjust downward another 200ish calories.
It absolutely is possible to lose 2+ pounds a week. I think Biggest Loser is proof of that. The problem is crashing your body like that will absolutely wreck your metabolism. Do it smart and you'll be able to keep the weight off.
Edit: You posted while I was writing that. I don't know how tall you are, but that's a severe calorie restriction at 200 pounds. But whatever. Good luck with your gym injury goals of 2014 while eating like a 5 foot tall woman.
