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.
-Approximately how many calories per day does Eric need for basal metabolic processes?

-Approximately how many calories per day does Eric need for basal metabolic processes?​

Quizplus · Accepted Answer

To determine the number of calories Eric needs for basal metabolic processes, we can use the Mifflin-St Jeor equation, which is based on age, sex, height, and weight. For Eric, the calculation would be:
(10 x 75 kg) + (6.25 x 173 cm) - (5 x 25 yrs) - 161 = 1,925 calories
This means that Eric needs approximately 1,925 calories per day just to support his body's basic processes. However, this does not include calories needed for physical activity. It's likely that Eric needs more than 1,925 calories per day to maintain his current weight, especially since he only engages in moderate physical activity. To lose weight, he would need to consume fewer calories than he burns through a combination of basal metabolic processes and physical activity. His current diet is likely contributing to excess calorie intake, as many processed foods are high in calories and low in nutrient density.
