Clinical Nutrition & Dietary Reference Tools

In medical nutrition therapy (MNT), precision calculations guide therapeutic diet planning, enterostomy tube feeding formulas, and total parenteral nutrition (TPN) parameters. Bedside calculators support registered dietitians (RDs) and nutrition support teams in estimating daily resting energy expenditure, assessing body mass parameters, and standardizing pregnancy weight guidelines.

BEDSIDE FAQs

Why is the Mifflin-St Jeor equation preferred over Harris-Benedict?

Multiple clinical trials have shown that the Mifflin-St Jeor equation provides the most accurate estimation of Resting Metabolic Rate (RMR) in modern populations, generally predicting within 10% of measured indirect calorimetry. It is less prone to overestimating caloric demands in overweight and obese patients compared to the older Harris-Benedict formulas.

• Men: RMR = (10 × Weight in kg) + (6.25 × Height in cm) - (5 × Age in years) + 5
• Women: RMR = (10 × Weight in kg) + (6.25 × Height in cm) - (5 × Age in years) - 161

How does physical activity factor into total daily energy expenditure (TDEE)?

Once Resting Metabolic Rate (RMR) is calculated, clinicians multiply the value by an Activity Factor (standardized physical activity coefficient ranging from 1.2 for sedentary bed-ridden patients, up to 1.9 for highly active individuals) to determine the Total Daily Energy Expenditure (TDEE) required to maintain mass baseline.
