## Nutrition and Diet Calculators Nutrition and Diet Calculators for the Medical Professional and layman alike – including Body Weight Calculator, Weight Management Agents, basal and resting metabolic rate, fiber calculators and protein requirements, calcium and vitamin D needs, energy calculators and total parenteral nutrition calculator.

Estimated ‘Calorie’ Calculators

Several of these calculators may be particularly useful for dieters.  Just about every single MAJOR calorie/ energy equation that has been released over the last 90 years is included below.   Each calculator has a customized printout option for easy analysis.  Recommendation: Try each calculator – print out the results –  then compare!

• Harris-Benedict Equation:  Estimation of total calories needed. MOST widely used equation for calculating basal metabolic rate and total calories.
• Revised Harris-Benedict Equation:The original Harris Benedict equation was revised in 1984. This updated equation can be used to calculate the basal metabolic rate and total calories.
• RESTING Metabolic Rate (RMR): Resting Metabolic Rate Calc – This equation can be used to calculate the RESTING metabolic rate and total calories. Mifflin-St Jeor equation.
• Schofield equation (BMR) : This equation was part of the previous government guidelines to formulate RDA’s and can be used to calculate the basal metabolic rate and total calories needed.
• Institute of Medicine Equation- LATEST EQUATION: IOM Equation-Estimated Energy Requirement (EER) Estimation of total calories needed. This equation is behind the 2005 Dietary Guidelines for Americans and the new food pyramid, MyPyramid.
• Energy Requirements in ICU patients – Ireton-Jones
• Check out the new BMR multi-calc .

Body Weight Calculators

• Adjusted Body Weight Calculator and Ideal Body Weight Calculator
• Body Mass Index Calculator – BMI – Determines if your weight is in proportion to your height based on Federal guidelines released by the National Heart, Lung, and Blood Institute. The BMI is helpful in determining health risks and appropriate interventions.
• Dieting Calculator – This calculator provides several useful outputs including the calculated ‘Body Mass Index’ or BMI. It will also estimate your ‘Basal Metabolic Rate’ or BMR. Also included is an estimate of your ‘Total Energy Expenditure’ or TEE which indicates the number of calories needed per day to maintain your current weight.
