1. What is the Weight-Adjusted Life Expectancy?

The weight-adjusted life expectancy calculation estimates how excess weight may impact overall life expectancy based on established medical research about the relationship between weight and longevity.

2. How Does the Calculator Work?

The calculator uses the equation:

Where:

• \( \text{Base LE} \) — Baseline life expectancy (years)
• \( \text{Overweight Factor} \) — Years of life lost per kg of excess weight
• \( \text{Excess Weight} \) — Weight above ideal range (kg)

Explanation: The equation provides a linear approximation of how excess weight may reduce life expectancy based on epidemiological studies.

3. Importance of Weight Adjustment

Details: Understanding the potential impact of weight on longevity can motivate healthy lifestyle changes and inform personal health decisions.

4. Using the Calculator

Tips: Enter your baseline life expectancy (available from actuarial tables), the appropriate overweight factor (typically 0.05-0.1 years/kg based on studies), and your excess weight in kilograms.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a general estimate based on population studies. Individual results may vary based on other health factors.

Q2: Where can I find my baseline life expectancy?
A: National health statistics or actuarial tables provide average life expectancies by age, gender, and country.

Q3: What's a typical overweight factor value?
A: Studies suggest values between 0.05-0.1 years lost per kg of excess weight, varying by degree of overweight.

Q4: Does this account for all weight-related health risks?
A: No, this is a simplified model. Excess weight affects different health risks in different ways.

Q5: Can losing weight reverse these effects?
A: Many studies show that weight loss, especially when maintained, can improve life expectancy.
