Final answer:
The Resting Energy Expenditure (REE) for a 45 year old male client who weighs 210 pounds and is 70 inches tall is closest to 1825 kcal/day, based on the Mifflin-St Jeor Equation for calculating REE in men.
Step-by-step explanation:
The question revolves around calculating the Resting Energy Expenditure (REE) of a 45 year old male client who weighs 210 pounds and is 70 inches tall. To calculate REE for a male, you can use the Mifflin-St Jeor Equation, which is one of the most accurate methods. The formula for men is:
REE = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (y) + 5
First, convert the client's weight from pounds to kilograms (1 pound = 0.453592 kg) and height from inches to centimeters (1 inch = 2.54 cm). Then apply the values to the formula:
Weight in kg = 210 lb × 0.453592 = 95.2543 kg
Height in cm = 70 in × 2.54 = 177.8 cm
Inserting these values into the equation gives:
REE = 10 × 95.2543 + 6.25 × 177.8 - 5 × 45 + 5
which calculates to approximately 1825 kcal/day.
