How many kilocalories do I need on daily basis? This is a question that most people who are healthy and maintain their body weight do not have to worry about. They maintain energy balance (calories in versus calories out) without thinking about it. But for those who have more difficulty maintaining their weight, estimating daily energy needs and keeping their kilocalorie intake in check may help them.

Anna and her sister Theresa weighed almost the same until Anna went to college. Everybody has heard about the freshman 15! And yes, it is happening to Anna. Her jeans seem to be tight, and she does not even want to step on the scale. What happened? What can she do? Anna and Theresa are only one year apart; both are 5 feet 4 inches tall and before Anna left home they both weighed 121 pounds. Both of them played on their school volleyball team, rode bikes to school, and were moderately active teenagers. Now in college, Anna studies way more than she did during high school, and so far she has not found friends to exercise with. She is not happy with her situation, but for now her life has become sedentary.

Part A - Daily Energy Needs for a Sedentary Person

What are Anna’s total daily energy needs based on her desired body weight and level of physical activity that will allow her to maintain her precollege body weight?

Formula for women:

BMR (kcal/day) = body weight in kg × 0.9 kcal/kg/hour × 24 hours/day

Round the final answer to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Total daily energy needs is a range; do not forget to enter two numbers, lower and upper range values respectively. Separate the lower and upper ranges, in that order, by a comma.

Ans- As we all know that the daily needs of energy kilocalories are different one with another. But normally we considered that the normal daily needs for men is 2700kilocalories and for the women is 2200kilocalories per day.

And for the sedentary person also,estimated ranges of sedentary women from 1600 to 2400calories per day and 2000 to 3000 calories per day for the adult men.

For the given sistuation, anna is in sedentary women category. So the energy needs for her is 1600-2400 calories per day only.
