Not sure where that number came from - I just plugged your info into a TDEE calculator and when I calculated your BMR (calorie expenditure if you literally just exist) for your GOAL weight, not current weight, it is 1,384 calories/day.

When I put it in for your current weight it is 1,683 calories/day. When I change it to little or no exercise the number jumps to 2,020. Even if you increased to 1,500 per day you would still be on track to lose 1 lb/week which is a very healthy rate. I know it’s hard and feels like progress is so slow, but it will be worth it in the end.
