Question

For a moderately active underweight adult man, you would recommend _____ Kcal/kg ideal body weight/day.

• A. 50
• B. 45
• C. 40
• D. 35

Hint:

Energy calculations for weight management are always based on ideal body weight (IBW) rather than actual weight.
This ensures nutrient delivery is targeted toward achieving a healthy body composition.

Answer 1

The Correct Option is C

The question asks about the recommended kilocalories per kilogram of ideal body weight per day for a moderately active underweight adult man. To answer this, we need to consider the general nutritional guidelines and recommendations.

The recommended energy intake depends on several factors including age, gender, activity level, and health status. For an underweight individual, increasing the caloric intake slightly above the normal recommendations is common to promote healthy weight gain.

For a moderately active adult male, typical recommendations might range from 35 to 40 kcal/kg of ideal body weight per day, depending on various factors including the need for weight gain and activity level.

In this context, the ideal recommendation for a moderately active underweight adult man would be to provide enough calories to support activity and promote gradual weight gain while ensuring nutritional needs are met. Hence, the correct option is:

• 40 kcal/kg ideal body weight/day

To justify this choice:

• 50 kcal/kg: This is typically higher than the usual recommendation for even an underweight individual unless the person is extremely active or in a special condition needing high caloric intake.
• 45 kcal/kg: This is also generally beyond standard guidelines for moderately active individuals.
• 40 kcal/kg: Suitable for moderately active individuals aiming for weight maintenance or slight gain.
• 35 kcal/kg: Typically suited for maintenance in normal weight individuals, not specifically for underweight persons needing to gain weight.
