BMR is your basal metabolic rate – or how many calories your body burns just to be alive.
Depending on your body type, height and weight a persons BMR can vary – Use this BMR calculator to figure yours
Typically it takes about 1200 to 2000 calories a day for a human to maintain normal organ functions and if you do strenuous work or regular exercise then you can multiply this number by 1 – 1.9% for activity
A 5’5″ F 140lbs and 30yrs has a BMR of about 1450kcals/day
1450 x 1.5 = 2175kcals
So she would need 2175kcals a day to MAINTAIN her 140lbs for the day. If she wants to lose weight then then she needs to eat 250kcals less a day to be at a calorie deficit.
This is a simple intro to BMR and Harris Benedict Equation
