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.

79.7 Kg BMI & Healthy Weight Context for UK Adults
At 79.7 kg, your BMI depends entirely on your height. For example, at an average UK adult height of 1.73m (5ft 8in), a weight of 79.7 kg gives a BMI of 26.6, which falls in the overweight category (25–29.9) according to NHS guidelines. However, at 1.80m (5ft 11in), the same weight gives a BMI of 24.6, which is within the healthy range (18.5–24.9). Use our free BMI calculator on this page to calculate your exact BMI instantly. For sustainable weight management, the NHS recommends losing no more than 0.5–1 kg per week through a combination of reduced-calorie diet and increased physical activity.
