At two weeks in, it is probably too soon to worry about cranking in that little bit extra a supplement might get you. I'd agree with JoeyD20, 1650 is probably a bit low for you given your activity level.
Remember, eating too little can make it hard to maintain muscle and will sabotage the fat loss in the long run, as your resting metabolic rate will likely suffer. Remember, the best fat loss plan, barring someone getting ready for a bodybuilding show, is slow and steady. Something that helps you stay fit and is sustainable.
Try logging your food and exercise on a diet & exercise software (you can use FitDay free online) and see how your calorie budget is. Remember that you can't lose more than about 1/4 to 1/3 a pound of fat a day, so anything over about 1,000 calorie deficit is going to be muscle sacrificing with no real fat loss benefit.
I'd aim for about half of that to help maintain lean mass. See how things go for a month, then tinker from there. If your waistline is getting smaller, you are making progress. If not, cut some more calories or add some more exercise. If you are seeing your waist shrink, and no muscle gains to the chest & hips, add a bit more food.
There are just so many variables in this process, and it takes time to tailor your program to get good results.
