## Ideal Body Weight Formulas

The equations to compute your ideal body weight (IBW) are listed below:

### The Broca equation

Women: IBW [kg] = (height[cm] - 100) - ((height[cm] - 100) × 15%)
Men: IBW [kg] = (height[cm] - 100) - ((height[cm] - 100) × 10%)

### The Robinson equation

Women: IBW [kg] = 49 kg + 1.7 kg × (height[in] - 60)
Men: IBW [kg] = 52 kg + 1.9 kg × (height[in] - 60)

### The Devine equation

Women: IBW [kg] = 45.5 kg + 2.3 kg × (height[in] - 60)
Men: IBW [kg] = 50 kg + 2.3 kg × (height[in] - 60)

### The Miller equation

Women: IBW [kg] = 53.1 kg + 1.36 kg × (height[in] - 60)
Men: IBW [kg] = 56.2 kg + 1.41 kg × (height[in] - 60)

### The Hamwi equation

Women: IBW [kg] = 45.5 kg + 2.2 kg × (height[in] - 60)
Men: IBW [kg] = 48 kg + 2.7 kg × (height[in] - 60)

### The Lemmens equation

Women, Men: IBW [kg] = 22 × height[m] 2

### BMI range equation

IBWmin [kg] = (18.5 / 703) × height[in] 2
IBWmax [kg] = (24.9 / 703) × height[in] 2

## What is Ideal Body Weight Calculator

The Ideal Body Weight (IBW) calculator is a tool used to estimate the optimal weight range for individuals based on their height and sometimes gender. The IBW is commonly used as a reference to assess whether a person's weight falls within a healthy range. Here's how an Ideal Body Weight calculator typically works:

1. Input Variables: To calculate IBW, the calculator requires two main inputs: height and, in some cases, gender. Height is usually measured in inches or centimeters.

2. Calculation Method: There are different formulas available to estimate the Ideal Body Weight depending on the reference used. One commonly used formula is the Devine formula:

• For males: IBW = 50 kg + 2.3 kg per inch over 5 feet
• For females: IBW = 45.5 kg + 2.3 kg per inch over 5 feet

This formula estimates the ideal weight based on a predetermined value for each inch over 5 feet of height.

3. Interpretation: The calculated Ideal Body Weight provides a target weight range that is considered healthy for a given height. It serves as a general guideline rather than an absolute measure.

Keep in mind that the Ideal Body Weight calculator provides estimations and may not account for individual variations in body composition, muscle mass, or other factors. It's important to consider other factors such as body fat percentage, muscle mass, and overall health when assessing weight goals.

Furthermore, it's essential to remember that healthy weight ranges can vary depending on various factors, including age, gender, bone structure, and muscle mass. Consulting with a healthcare professional or registered dietitian can provide more personalized guidance on setting and achieving a healthy weight for your specific circumstances.

## Ideal Body Weight Calculator Example

Certainly! Here's an example of using a table to calculate the ideal body weight for different individuals:

Assume the following information for three individuals:

Individual Gender Height (inches) Ideal Body Weight (lbs)
Person A Male 72 178
Person B Female 65 136
Person C Male 68 160

To calculate the ideal body weight for each person, we can use gender-specific formulas:

For males: Ideal Body Weight = 50 + 2.3 * (Height - 60)

For females: Ideal Body Weight = 45.5 + 2.3 * (Height - 60)

Using the given values, we can calculate the ideal body weight for each individual:

For Person A: Ideal Body Weight = 50 + 2.3 * (72 - 60) = 50 + 2.3 * 12 = 50 + 27.6 = 77.6 lbs ≈ 78 lbs

For Person B: Ideal Body Weight = 45.5 + 2.3 * (65 - 60) = 45.5 + 2.3 * 5 = 45.5 + 11.5 = 57 lbs

For Person C: Ideal Body Weight = 50 + 2.3 * (68 - 60) = 50 + 2.3 * 8 = 50 + 18.4 = 68.4 lbs ≈ 68 lbs

Therefore, the ideal body weight for Person A is approximately 78 lbs, for Person B is 57 lbs, and for Person C is approximately 68 lbs.

Using a table allows you to input the gender and height for each individual and calculate their respective ideal body weight. Ideal body weight is an estimation of a healthy weight range based on an individual's height and gender. It can be useful for setting weight goals, assessing weight-related health risks, and evaluating weight loss progress. However, it's important to note that individual variations and other factors should also be considered. Consultation with a healthcare professional or registered dietitian is recommended for personalized weight management advice.
