Assuming you meant lbs, rather than kilos, I ran your numbers through the BMR (Basic Metabolic Rate) formula I found online - 1422 calories - is the amount of calories you'd burn if you simply laid in bed all day and did absolutely nothing. This needs to be adjusted according to your activity level as per the following:
1. If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2
2. If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375
3. If you are moderatetely active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55
4. If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725
5. If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9
So, if you were lightly active, you'd take the 1422, and multiply it by 1.375 and come out with 1955 calories to maintain your current weight. Using Christa's suggestion, you'd then want to have around 1455 calories if you wanted to produce weight loss. Hope this helps.
Edited to add: And what Fly said is true - (as you can see from the formulas above) the more exercise you get, the more calories you need to maintain.
