What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Healthy Weight Ranges at Different Heights
To understand if 71.5kg (157.6 lbs) is healthy for you, you need to calculate your BMI (body mass index). The same weight can be healthy for a taller person but overweight for someone shorter. Here are three real-world examples showing how height changes everything:
- At 5ft 6in (168cm): 71.5kg gives a BMI of 23.1 — within the healthy range (18.5–24.9)
- At 5ft 3in (160cm): 71.5kg gives a BMI of 28.2 — classified as overweight (25.0–29.9)
- At 5ft 10in (178cm): 71.5kg gives a BMI of 22.8 — within the healthy range
To convert kilograms to stone, divide 71.5 by 6.35 to get approximately 11 stone 3 pounds. Use our weight converter above to switch between metric to imperial weight measurements instantly. Your GP can provide personalised advice based on your individual height, build, and health history.

NHS Guidance and Waist Measurement
According to NHS guidelines, a healthy BMI is 18.5 to 24.9 for most UK adults. If your BMI falls within this range at your height, your weight is considered healthy from a population health perspective. However, BMI has limitations — it doesn't account for muscle mass or where fat is stored. That's why the NHS also recommends measuring your waist circumference: over 94cm (37 inches) for men or 80cm (31.5 inches) for women indicates increased health risk, regardless of BMI.
If you're outside the healthy weight range, small changes make a real difference. A 5–10% reduction in body weight can improve blood pressure, blood sugar control, and energy levels. Your GP can discuss sustainable approaches tailored to your circumstances.
