Daily Caloric Intake for a 5-Foot Tall, 171-Pound Child

Critical Assessment: This Child Has Severe Obesity

This child requires immediate weight management intervention, not standard caloric recommendations for healthy children. At 5 feet tall and 171 pounds, this child has a BMI of approximately 33.4 kg/m², which places them well above the 95th percentile for any pediatric age group, meeting criteria for severe obesity 1.

Recommended Caloric Intake

For weight management in this child with severe obesity, prescribe 1,200-1,600 calories per day, creating a 500-750 kcal/day deficit below their estimated maintenance needs. 1, 2

Calculation Approach

To determine the appropriate caloric target, first calculate resting energy expenditure (REE) using the Schofield equation 1:

• If this child is 10-18 years old:

  • Boys: REE = 17.7 × (77.6 kg) + 658 = 2,032 kcal/day
  • Girls: REE = 13.4 × (77.6 kg) + 692 = 1,732 kcal/day

• If this child is 3-10 years old:

  • Boys: REE = 22.7 × (77.6 kg) + 504 = 2,265 kcal/day
  • Girls: REE = 20.3 × (77.6 kg) + 486 = 2,062 kcal/day

Total energy expenditure (TEE) for a sedentary child would be REE × 1.2 (physical activity level), yielding approximately 2,078-2,718 kcal/day depending on age and sex. 1

To achieve clinically meaningful weight loss, subtract 500-750 kcal/day from TEE, targeting 1,200-1,800 kcal/day, with minimum intake not falling below 1,000-1,200 kcal/day. 2

Dietary Composition Using MyPlate Method

The MyPlate approach should guide all food choices, emphasizing low added sugar, moderate balanced fats, adequate dairy, whole grains, proteins, fruits and vegetables, with appropriate portion sizes. 1

Specific Daily Food Group Targets at 1,400-1,600 Calories 1:

• Fruits: 1.5 cups/day (fresh, frozen, or canned unsweetened preferred) 1
• Vegetables: 2 cups/day total 1:
  • Dark green vegetables: 1.5 cups/week 1
  • Red/orange vegetables: 4 cups/week 1
  • Beans and peas: 1 cup/week 1
  • Starchy vegetables: 4 cups/week 1
  • Other vegetables: 3.5 cups/week 1
• Grains: 5 oz equivalents/day (at least half whole grains) 1
• Protein foods: 5 oz equivalents/day 1:
  • Lean meat, poultry, eggs: 23 oz/week 1
  • Fish (preferably oily): 8 oz/week 1
  • Nuts, seeds, legumes (unsalted): 4 oz/week 1
• Dairy: 3 cups/day (fat-free or low-fat) 1
• Oils: 30g/day (2 tablespoons) from unsaturated sources 1
• Fiber: 25g/day 1
• Sodium: Maximum 1,602 mg/day 1
• Added sugars: Maximum 54 kcal/day (13.5g) 1

Critical Dietary Interventions

Eliminate sugar-sweetened beverages immediately—this single intervention can lead to marked reductions in daily caloric intake and improve weight in the short term. 1

Avoid these specific foods: 3

• 100% fruit juice 3
• Sugar-sweetened beverages 1, 3
• High-calorie sauces (Alfredo, cream sauces, cheese sauces) 3
• Foods high in added sugars 3
• Foods high in saturated fat 3

Physical Activity Requirements

This child must engage in 60 minutes of moderate-to-vigorous physical activity daily, plus muscle- and bone-strengthening activities at least 3 days per week. 3

• Unstructured play is effective and preferred for younger children 1
• Older children can participate in sports teams or noncompetitive activities like dance or martial arts 1
• Limit screen time to ≤2 hours per day of recreational use 3

Family-Based Approach

Parent involvement in this child's weight management program is essential, especially if the program focuses on both parent and child weight simultaneously—this approach demonstrates the strongest evidence for success. 1

• Parents control the food and electronic environment 1
• Meals should be offered as a family when possible 3
• Breakfast should be consumed daily 3
• Provide 3-4 meals with 1-2 snacks per day 3

Expected Outcomes and Monitoring

Because this child has severe obesity, gradual weight loss (not just weight maintenance) will provide health benefits. 1

• Younger children with mild obesity can "grow into" a healthier BMI by maintaining weight, but this child requires actual weight loss 1
• Monitor weight regularly and adjust caloric intake based on weight trends 2
• Rapid weight loss can delay linear growth, so avoid highly restrictive diets in preadolescents 1

Common Pitfalls to Avoid

• Do not use standard caloric recommendations for healthy children (1,600-2,600 kcal/day for this age range)—this child requires a weight loss prescription 3
• Avoid highly restrictive diets that could impair linear growth 1
• Do not rely on exercise alone without dietary modification 1
• Recognize that targeted exercise like treadmills may be perceived as boring or punitive by children 1

Advanced Treatment Considerations

If behavioral interventions fail after 6-12 months of moderate-to-high intensity multicomponent programming (25-75 hours of contact), consider:

• Orlistat (approved for age ≥12 years) with modest efficacy 1
• Bariatric surgery evaluation (gastric bypass or sleeve gastrectomy have demonstrated good outcomes in adolescents with severe obesity) 1
