**Question:** The recommended daily energy intake of an adult woman with heavy work is –

A. 2000 calories
B. 2500 calories
C. 2200 calories
D. 3000 calories

**Core Concept:** Recommended Daily Energy Intake (RDI) is the amount of energy required by an individual to maintain their body weight in a state of energy balance. This includes basal energy expenditure (BEE) and physical activity level (PAL).

**Why the Correct Answer is Right:** The correct answer is 2500 calories because this value represents a moderate level of physical activity, which includes moderate workloads and sedentary lifestyle. In the case of an adult woman with heavy work, we need to consider increased energy expenditure due to higher physical activity. The formula for calculating RDI is as follows:

BEE (Basal Energy Expenditure): 1.2 x body weight (kg) x 24 (hours)
PAL (Physical Activity Level): 1.5 (sedentary) to 2.0 (moderate activity)
Total Energy Expenditure (TEE): BEE + (PAL x BEE)

**Why Each Wrong Option is Incorrect:**

A. 2000 calories is the recommended daily energy intake for an average woman without considering the increased energy expenditure due to heavy work.
B. 3000 calories is too high and not suitable for an adult woman with heavy work.
C. 2200 calories is slightly higher than the correct answer but does not account for the heavy workload.
D. 3000 calories is too high and not suitable for an adult woman with heavy work.

**Clinical Pearl:**

Understanding the individual's physical activity level and workload is essential when determining their energy requirements. A higher energy intake is required for individuals with heavy workloads to maintain their body weight and prevent weight loss or gain. This highlights the importance of considering the patient's lifestyle and occupation when prescribing dietary recommendations.
