Dieting Calculator Estimate Your 'Basal Metabolic Rate' Or BMR

Dieting Calculator

Background

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.

Input:

Age: Height:

Weight:

How much weight do you want to lose? (same units as above)

Gender:

Daily activity level?

Current daily activity level?

Sedentary. Little to no regular exercise.
(factor 1.2)

Mild activity level: Intensive exercise for at least 20 minutes 1 to 3 times per week. This may include such things as bicycling, jogging, basketball, swimming, skating, etc. If you do not exercise regularly, but you maintain a busy life style that requires you to walk frequently for long periods, you meet the requirements of this level.
(factor 1.375)

Moderate activity level: Intensive exercise for at least 30 to 60 minutes 3 to 4 times per week. Any of the activities listed above will qualify. (factor 1.55)

Heavy or (Labor-intensive) activity level: Intensive exercise for 60 minutes or greater 5 to 7 days per week (see sample activities above). Labor-intensive occupations also qualify for this level. Labor-intensive occupations include construction work (brick laying, carpentry, general labor, etc.). Also farming, landscape worker or similar occupations. (factor 1.7)

Background

Background information:
The BMI (body mass index) 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.

Basal energy expenditure: the amount of energy required to maintain the body's normal metabolic activity, i.e. respiration, maintenance of body temperature etc.

Basal Energy Expenditure Equations:

Male: BEE = 66.67 + 13.75W + 5H - 6.76A

Female: BEE = 665.1 + 9.56W +1.85H -4.68A.

H= height in cm , W= weight in kg, A= age in years.

Maintain current weight (calories) = BEE x activity factor

Maximum calories allowed that promote weight loss: (BEE x activity factor) - 500

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!
Basal Metabolic Rate (BMR) Overview.

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.

Fiber Calculators

Soluble Fiber Calculator - Cholesterol lowering - Soluble fiber: viscous fiber that delays gastric emptying and can result in an extended feeling of fullness. Need at least 7 grams per day to maximize cholesterol lowering benefits.
TOTAL Fiber Calculator - Great tool for dieters! - Insoluble fiber: does not dissolve in water and is not affected by digestive enzymes in the gastrointestinal tract. Insoluble fiber provides bulk which eases defecation.
Daily Fiber Requirements based on AGE

Protein

Protein requirements (daily) - calculate the amount of protein that should be consumed daily based on the latest guidelines.
