Ideal Weight and BMI for Women: Calculating Healthy Range for a 25-Year-Old

Body Mass Index (BMI) is a screening tool calculated as:

BMI = weight (kg) ÷ [height (m)]²

Healthy BMI Range (Adults)

• Underweight: < 18.5
• Normal: 18.5 – 24.9
• Overweight: 25 – 29.9
• Obesity: ≥ 30

Example Calculation

For a 5'4" (1.63 m) woman targeting BMI 22 (mid-normal):

Ideal weight = 22 × (1.63)² = 22 × 2.6569 ≈ 58.5 kg (129 lbs).

Note: The original example used a 7-foot (2.13 m) height, which is extremely rare. The above uses a more typical stature.

Limitations of BMI

• Does not distinguish muscle from fat.
• Less accurate in athletes, elderly, and certain ethnic groups.
• Does not capture fat distribution (visceral vs. subcutaneous).

For personalized assessment, consult a healthcare provider who can evaluate body composition, waist circumference, and metabolic health.
