What Does a BMI of 24 Mean for Women?
A BMI of 24 falls comfortably within the healthy weight range according to NHS guidelines. For women, this BMI indicates that your weight is proportionate to your height and puts you at lower risk of weight-related health conditions. However, BMI is just one health marker — your GP may also consider waist circumference, fitness level, and overall health when assessing your wellbeing. Use our free BMI calculator to check your personal BMI and understand where you fall on the NHS scale. If you're curious about your ideal weight range, our weight converter can help you understand what healthy weights look like at your height.

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.
NHS BMI Categories and What They Mean
The NHS BMI formula divides your weight in kilograms by your height in metres squared. For women, a healthy BMI range is between 18.5 and 24.9, which means a BMI of 24 puts you in the optimal zone. This bmi range uk is based on research showing reduced risk of type 2 diabetes, heart disease, and certain cancers.
According to nhs bmi guidance, women with a BMI below 18.5 are classified as underweight, 25.0–29.9 as overweight, and 30.0 or above as obese. Each bmi categories uk carries different health considerations. However, it's important to note bmi limitations — the metric doesn't distinguish between muscle and fat, so a very athletic woman might have a higher BMI despite low body fat. For people of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends assessing health risk at slightly lower thresholds due to increased vulnerability to metabolic conditions at lower BMI levels.

NHS Weight Management Support and Maintaining Your Health

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Is a BMI of 24 healthy for all women?
Yes, a BMI of 24 is within the healthy range (18.5–24.9) for most women according to NHS guidelines. However, if you're of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends lower thresholds (18.5–22.9), so 24 would be slightly above the recommended range for these populations.
What weight in stone does a BMI of 24 correspond to?
It depends on your height. At 5ft 6in (168cm), a BMI of 24 equals approximately 64kg (10st 1lb). At 5ft 4in (163cm), it's about 61kg (9st 9lb). Use our weight converter and BMI calculator above to find your exact healthy weight range at your specific height.
Should I try to lose weight if my BMI is 24?
No. If you have a BMI of 24 and feel well, the NHS recommends maintaining your current weight through balanced eating and regular physical activity. Weight loss is not necessary unless advised by your GP based on your overall health profile.
What does waist circumference tell me if my BMI is 24?
Even with a healthy BMI, waist circumference matters. For women, a waist above 80cm (31.5in) indicates increased health risk, and above 88cm (34.5in) indicates high risk. Your GP can advise on whether your waist measurement suggests additional health monitoring.
How do I maintain a BMI of 24 long-term?
Focus on consistent, sustainable habits: eat a balanced diet rich in vegetables, whole grains, and lean protein; aim for 150+ minutes of moderate activity weekly; stay hydrated; and get adequate sleep. Regular check-ins with your GP help ensure your weight remains stable and healthy.
