Final answer:
To determine how many kcal Dave should consume, we need to consider his age, sex, weight, height, activity level, and growth rate. The Schofield equation is often used to estimate energy needs for children.
Step-by-step explanation:
To determine how many kcal Dave should consume, we need to consider his age, sex, weight, height, activity level, and growth rate. Since Dave is five years old, we can use an estimation method to calculate his energy needs. The formula often used is the Schofield equation.
For a five-year-old boy, the Schofield equation is:
Kcal/day = 61.0 + (9.4 x weight in kg) + (1.31 x height in cm) - (0.02 x age in years)
Without specific information about Dave's weight and height, we can't provide an exact number of kcal he should consume. However, if we have those values, we can use the formula to calculate his energy needs.
