So you feel a little better, your, from what I've been reading, your BMR is what your
body would require if you did absolutely nothing all day. It's basiclly what it takes for you to keep all necessary bodily functions...functioning. Since, I'm assuming that even without the exercise, you walk around, do household chores, work, etc., you are actually burning more than your BMR
I found this, if it helps:
Harris Benedict Formula
To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows:
If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2
If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375
If you are moderatetely active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55
If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725
If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9
Basically, what it takes to maintain your
body weight is your BMR times anywhere from 1.2 to 1.9...so, from the appropriate new calorie need.
To lose a
pound a week, you subtract 500
calories a day, 2
pounds, 1000 a day.--but, as Sophie pointed out, I think the 1300
calories aday is a good plan, at least to start. This are just numbers to help your peace of mind.
