1. What Are Ideal Weight Formulas?

Ideal weight formulas are mathematical equations that estimate a healthy body weight based on height and sometimes gender. Different formulas may produce slightly different results as they were developed using different population samples and methodologies.

2. How Do These Formulas Work?

The calculator uses seven different formulas:

Devine (1974): Originally developed for medication dosing, with different formulas for men and women
Robinson (1983): Based on Metropolitan Life Insurance Company data
Miller (1983): Another formula based on actuarial statistics
Hamwi (1964): Developed for diabetes management
Broca (1871): One of the oldest formulas, simple height-based calculation
Lemmens (2005): Based on BMI of 22 kg/m²
Peterson (2016): Newer formula based on NHANES data

3. Importance of Ideal Weight Calculation

Details: While BMI is more commonly used today, ideal weight formulas can be helpful for quick estimation, medication dosing, and as reference points for weight management goals.

4. Using the Calculator

Tips: Enter your height in centimeters, select your gender (for formulas that use it), and click Calculate. The calculator will display results from all seven formulas.

5. Frequently Asked Questions (FAQ)

Q1: Which formula is most accurate?
A: No single formula is perfect for everyone. Newer formulas like Peterson may be more accurate for most people, but results should be interpreted in clinical context.

Q2: Why are there different formulas?
A: Different researchers developed formulas based on different populations and purposes (insurance data vs. medical use).

Q3: Should I aim for the average of all formulas?
A: Not necessarily. Consult with a healthcare provider to determine your healthy weight range based on multiple factors.

Q4: How do these compare to BMI?
A: These formulas typically produce weights that correspond to BMI values between 18.5-25 kg/m², but with different approaches.

Q5: Do these work for athletes?
A: These formulas don't account for muscle mass, so may underestimate healthy weight for very muscular individuals.
