1. What is BMI?

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. For men over 60, the healthy range is adjusted to 23-29 kg/m² to account for age-related changes in body composition.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula with adjusted ranges for men over 60:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in meters

Interpretation for men over 60:

• Below 23: Underweight
• 23-29: Normal weight
• Above 29: Overweight

3. Importance of BMI Calculation for Men Over 60

Details: Maintaining a healthy BMI becomes increasingly important with age. The adjusted range accounts for natural changes in body composition and helps prevent sarcopenia (muscle loss) while still identifying obesity-related risks.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For height, you can convert from cm to m by dividing by 100 (e.g., 175 cm = 1.75 m). Measurements should be current for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why is the range different for men over 60?
A: Older adults naturally have more body fat and less muscle mass, so the healthy range is adjusted upward to prevent undernutrition while still identifying obesity risks.

Q2: Is BMI accurate for very muscular older men?
A: BMI may overestimate body fat in muscular individuals. Additional measures like waist circumference may be helpful.

Q3: Should weight loss be pursued if BMI is above 29?
A: Weight loss should focus on fat loss while preserving muscle. Consult a healthcare provider before starting any weight loss program.

Q4: What if my BMI is below 23?
A: Being underweight can increase frailty risk. Focus on nutrient-dense foods and strength training to maintain healthy weight.

Q5: How often should BMI be checked?
A: For men over 60, checking every 3-6 months is reasonable unless significant weight changes occur.
