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.

BMI Context — What 136kg Means for Your Health
At 136kg, your BMI depends on your height. For example, at an average UK adult height of 1.73m (5ft 8in), 136kg gives a BMI of approximately 45.5, which falls into the severely obese category according to NHS guidelines. Use our free BMI calculator above to check your personal BMI instantly and see your weight category.
The NHS recommends a healthy weight range as BMI 18.5–24.9. Even a modest weight loss of 5–10% of body weight can improve blood pressure, blood sugar control, and overall health outcomes. If you're concerned about your weight, your GP can provide personalised advice and discuss the options available to you.
