a 16 year old girl who is only 5'3" and only weighs 115 lbs. should not lose any weight.

More info is needed. 2000 calories is normal per day for adults. For you, we need to know (1) basal metabolic rate - BMR (2) physical activity, and (3) thermic effect of food. The last one is the amount of energy your body uses to digest the food you eat. To calculate the no. of calories you expend in this process, multiply the total no. of calories you eat in a day by 0.10 (10%). BMR is the amt of energy your body needs to function at rest. This accounts for 60-70% of calories burned in a day --- a way to figure this is the Harris-Benedict forumula: Adult female: 655 + (4.3 X weight in lbs) + (4.7 X height in inches) - (4.7 X age in years) Two pounds per week is a lot to lose and keep off.

According to the charts, you don't need to lose weight --- If you are medium frame, then at 5'3", you should weigh 121-135. If you are small frame, you should weigh 111-124 - so your weight is perfect for a small framed person. Here is how you figure out whether you are small-med.-large in frame-----

This is the method the Metropolitan Life Ins. Co. uses to calculate frame size:
