I have to agree with Rebound. As your body approaches its "comfortable" weight, it's harder to get rid of the last few pounds. If you're burning that many calories, I'd definitely say increase your caloric intake. If you have a juicer, try drinking a fresh vegetable juice after your runs every other day (2 carrots, 2 celery stalks, 1 small beet, 1/2 cucumber, 1/4 inch piece of ginger root, 1 apple......it's good!) and that will add very healthy calories and other health benefits as well.
