What is the approximate daily caloric need of a 45-year-old, 176-pound male with a very light activity level?

1. A. 3800 calories

2. B. 1983 calories

3. C. 2349 calories

4. D. 4100 calories

The correct answer is: C. 2349 calories

The calculation of daily caloric needs for an individual takes into account factors such as age, weight, and activity level. For a 45-year-old male weighing 176 pounds, with a very light activity level—which typically includes minimal exercise and everyday activities—the estimated caloric requirements are primarily based on the Basal Metabolic Rate (BMR) and the Physical Activity Level (PAL). The BMR can be calculated using established equations, such as the Mifflin-St Jeor equation, which provides a reliable estimate of caloric needs at rest. After determining the BMR, you adjust it according to the individual's activity level. Given that this male has a very light activity level, the appropriate multiplier would likely be around 1.2. For this specific scenario, using the estimated calculations: 1. Calculate BMR: Using averages for a man of this weight and age, the BMR may fall around 1,700 to 1,800 calories. 2. Adjust for activity level: Multiplying that BMR by 1.2 accounts for the very light activity, yielding a rough estimate in the vicinity of 2,000 to 2,300 calories per day. This approximation aligns closely with the option that indicates 2
