Final answer:
Sam, being an inactive male who spends most of his time sitting, would fall into the lower end of the range of calorie requirements. To estimate the appropriate total number of calories he needs to maintain his body weight, we can use the Harris-Benedict equation to calculate his basal metabolic rate (BMR). However, since Sam's age is not provided, we cannot calculate his exact BMR. But assuming a typical age range, his BMR would be around 1600-1800 calories per day.
Step-by-step explanation:
On average, a person needs 1500 to 2000 calories per day to sustain daily activities. However, the total number of calories needed by an individual depends on various factors such as body mass, age, height, gender, activity level, and amount of exercise. Based on the information provided, Sam is an inactive male who spends most of his time sitting. In this case, he would fall into the lower end of the range of calorie requirements.
To calculate the appropriate total number of calories Sam needs daily to maintain his body weight, it's recommended to start with his basal metabolic rate (BMR). The BMR is the number of calories needed to maintain basic bodily functions at rest. We can estimate Sam's BMR using the Harris-Benedict equation for men:
BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age in years)
For Sam, his BMR calculation would be:
BMR = 66 + (6.23 x 150) + (12.7 x 70) - (6.8 x age)
Since Sam's age is not provided, we cannot calculate his exact BMR. However, assuming a typical age range for a college student, we can estimate his BMR to be around 1600-1800 calories per day.
