Increasing calories while still 20 lbs from goal weight?

Runagain_4

After months of a verrrrrry slow loss and week-long plateaus (average weight loss of 1 lb per week over 10 weeks), the last week has seen my weight drop daily (I weigh in daily to establish a trend).
While I'm thrilled to be headed in the right direction, I'm afraid quick losses won't be sustainable or that my body will adjust completely to my low calorie intake (between 1200-1500 a day).
My diet has remained unchanged, but I've increased my steps significantly over the last two weeks and stayed away from alcohol. MFP pals, has anyone ever upped their calories while still trying to lose? (I have 18 lbs to go, so I'm still far from maintenance.) Should I try increasing calories in or should I just ride the wave?
How did you go about increasing calories? If you did, did it work? I'm truly looking for long-term sustainable weight loss, not an overnight fix (as nice as that would be, it rarely lasts).
Advice appreciated.

Eating more than you burn will never make anyone lose (more) weight.

However, I've definitely eaten more than when i first started and lost weight, but that's because I'm a lot more active now than when i first started. If i were no more active, then there would be no way to eat more and stay in a calorie deficit

As stated if you are active (doing cardio or heavy weights) you can get away with increasing calories otherwise no.

If you increase your calorie intake, but still maintain an overall calorie deficit, you should still lose weight, just more slowly.

Also, I don't think that losing an average of 1 lb per week is slow progress at all!
