By using
Zite on my iPhone, I
found the formula for a woman's BMR (Basal Metabolic Rate). It was
startling to find out the rather low number of calories (1300+) I could
eat to maintain my weight--if I sat around all the time. Still, it gave
me a baseline idea of the number calories for a non-active day.
"The
National Institutes of Health reports that the best way to lose weight
is by taking in fewer calories than you use. That does not mean you
shouldn’t watch what you eat. In fact, by not limiting your calorie
intake to a number formulated to suit your age, height, activity level
and gender, you could sabotage your chances of getting to an appropriate
weight.
"Basal Metabolic Rate (BMR)
The Basal Metabolic Rate, or BMR, which is sometimes interchangeable
with your resting metabolic rate, is a calculation of the number of
calories you burn when using the least amount of energy, such as when
you’re asleep. By determining how many calories your body uses when
doing nothing, you can establish how many calories you need to take in
each day to maintain — not lose — your current weight."
How To Calculating Your BMR:
To calculate your BMR use this formula, which is specifically tailored for women:
655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) – ( 4.7 x age in years ) = BMR
