How many calories should an inactive 14 year old girl consume?

usually the amount of calories most people should have is 1200. but here is the simplest way to find your basic daily calorie needs: Basal Metabolic Rate (BMR) = 24 x Weight (lb)/2.2 OR Basal Metabolic Rate (BMR) = 24 x Weight (kg) The BMR is then multiplied by a number representing the individuals activity level: Sedentary BMR x 1.45

Light BMR x 1.60

Medium BMR x 1.70

Heavy BMR x 1.88 So for example if you weigh 125 pounds and hit the aerobic studio 3 times per week your daily caloric requirements would be: 1.70 x (24 x 125/2.2) = 1.70 x 1363.63 = 2318

Generally, eating more than this number of calories increases weight and less than this number allows weight reduction. However, BMR does not take into account extremes of activity or inactivity. Therefore, BMR should be used as an approximation.
