Sounds like, if you decrease your exercise and increase your calories, you'll be "changing it up", which is a good strategy. Then, you can go back to your regular routine, and might begin to lose again.
I read your blog. Your BMR is the number of calories that you need to maintain your weight. Perhaps the 1320-1670 calories that SparkPeople tells you is the number of calories that you need to lose weight? That would explain the difference. At any rate, if your BMR is 1695 to 1995 calories per day, I'd suggest, in order to lose that your weight-loss calorie range should be about 1200-1495 calories per day. That's decreasing calories by about 500 per day (and not going below 1200 per day). At that rate (500 calories x 7 days), you'd lose 3500 calories in a week, and, 3500 calories = one pound.
Eating too little is certainly a possibility to consider. If you go below 1200 calories, be sure that, at least once every 2-3 days, you eat at least 1200 calories. This "tricks" your metabolism into not believing that you are starving your body, and it will not likely go into "starvation mode" and hang on to fat, calories and weight. In fact, calorie cycling can be a good strategy. Eat less on some days, and more on others. Being careful to eat "enough" at least once every 3-4 days (twice a week minimum).
