How many calories?

I'm almost 10 months out from RNY, lost about 140lbs, and I'm still on my journey to lose more. I'm confused as to how many calories I should be consuming in a day. I just started strength training 3x a week, plus an additional 2 days a week of straight cardio. Does this also effect how many calories I should eat in a day? My diet is mostly protein, veggies, and fruits and the majority of my carbs come from whole grains.

We had surgery the same day, and I am wondering the same thing. If you get any info, please post! right know I am at about 1000 calories a day give or take. I hope I am not over doing it!!!
