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.
Understanding Your Weight In Context
At 11 stone 5 pounds (72.57 kg), your weight falls into a specific range that depends on your height, age, and overall health profile. The NHS uses BMI (Body Mass Index) to assess whether a weight is healthy for a given height. For example:
- If you're 5ft 6in (168cm) tall, a weight of 72.57 kg gives a BMI of approximately 26.2 — in the overweight category (BMI 25.0–29.9)
- If you're 5ft 10in (178cm) tall, the same weight gives a BMI of approximately 24.1 — in the healthy weight range (BMI 18.5–24.9)
- If you're 5ft 2in (157cm) tall, a weight of 72.57 kg gives a BMI of approximately 29.4 — still overweight but approaching the obese threshold
Use the free BMI calculator on this page to calculate your exact BMI using your height and current weight. BMI is a useful screening tool, but remember it doesn't account for muscle mass — muscle is denser than fat, so athletes may have a higher BMI despite being very fit.

Weight Management And Next Steps
If your BMI indicates you're overweight or obese, there are several evidence-based approaches to support weight management. The NHS recommends sustainable weight loss of 0.5 to 1 kg per week through a combination of reduced-calorie diet and increased physical activity. For some adults, prescription weight loss medications may be appropriate — these are available through NHS specialist weight management services or private prescribing, and always require clinical assessment by a licensed GP or prescriber.
Your first step is to speak with your GP about your weight and health goals. They can assess your individual situation, discuss lifestyle changes, and explore whether any additional support or treatment might benefit you. The free weight converter and BMI calculator on this page are helpful tools to track your progress over time.

Common questions about BMI, weight loss medications, and our free UK tools.
How do I convert 11 stone 5 to kg?

Is 11 stone 5 a healthy weight?
Whether 11 stone 5 is healthy depends on your height, age, and overall health. The NHS uses BMI ranges to assess this: healthy BMI is 18.5–24.9. Some adults at this weight will fall within the healthy range; others may be overweight or obese. Your GP can give personalised advice about what's healthy for you individually.
How much weight would I lose with Wegovy at this weight?
Wegovy (semaglutide) is a prescription-only weight loss injection. In clinical trials (STEP-1), people lost an average of about 14.9% of body weight over 68 weeks. At 72.57 kg, that's roughly 10–11 kg on average — though individual results vary significantly. Try our GLP-1 weight loss calculator to estimate potential outcomes at different doses.
How do I know if I need weight loss support?
If your BMI is 30 or above, or 27–29 if you have weight-related health conditions (like high blood pressure or type 2 diabetes), you may be eligible for support. The NHS recommends speaking with your GP, who can assess your health and discuss whether lifestyle changes, weight loss programmes, or prescription treatment might help.
