Eric signed up for a nutrition class this semester with the hope that he would learn how to improve his diet and lose weight in the process.Eric has had a difficult time in the past understanding important aspects of energy balance,such as how many calories his diet should provide for weight loss and how to determine whether a food provides only a few or many calories.Eric weighs 175 pounds and is 5' 8".He enjoys playing sports such as basketball,softball,and soccer,but most days of the week he is too busy with classes and school work to engage in much physical activity.Generally,he sits most of the day and spends two to four hours per day walking and moving around.
Eric's diet consists mainly of processed foods and he tries to avoid eating at fast food restaurants.A typical day includes a donut or pastry and a coffee with cream and sugar for breakfast,a couple of sandwiches with bologna,salami,and cheese on white bread for lunch,and one or two frozen entrées from his freezer such as a fried chicken,Salisbury steak,or a cheese enchilada for dinner.Eric feels like the amount of food he eats is reasonable,and he cannot understand why he is not losing weight.
-Calculate the total number of calories Eric needs each day to maintain his current body weight.
A)3,055 calories
B)3,176 calories
C)3,245 calories
D)3,385 calories
E)3,462 calories

To calculate the total number of calories Eric needs to maintain his current weight, we can use the Harris-Benedict equation. The formula for men is:
BMR = 88.36 + (13.4 x weight in kg) + (4.8 x height in cm) - (5.7 x age in years)
Based on Eric's weight and height, we can calculate his BMR to be:
BMR = 88.36 + (13.4 x 79.38) + (4.8 x 172.72) - (5.7 x 0)
BMR = 1,845.57
To calculate Eric's total daily energy expenditure (TDEE), we need to multiply his BMR by his activity level. Since Eric is mostly sedentary, we will use an activity factor of 1.2.
TDEE = BMR x activity factor
TDEE = 1,845.57 x 1.2
TDEE = 2,214.68
Therefore, to maintain his current body weight, Eric needs approximately 2,215 calories per day. Since none of the answer choices are exact, we can choose the closest option, which is B (3,176 calories).
