A BMI of 27 is classed as overweight for most adults (NHS). For people of South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean background it is classed as overweight (increased risk) (NICE). The healthy range is 18.5 to 24.9.

What a BMI of 27 means
Body mass index (BMI) compares your weight with your height. A BMI of 27 means you weigh 27 kilograms for every square metre of your height. Using the NHS categories, a BMI of 27 is classed as overweight for most adults.
Most adults
BMI 27 = overweight. NHS ranges: under 18.5 underweight, 18.5–24.9 healthy, 25–29.9 overweight, 30+ obesity.
South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean
BMI 27 = overweight (increased risk). NICE uses lower cut-offs of 23 and 27.5 because health risks start at a lower BMI.
Your BMI is 2.1 points above the top of the healthy range (24.9). For comparison, the average BMI of adults in England is 27.6 (Health Survey for England 2022), and 64% of adults have a BMI of 25 or more.

A BMI of 27 for women and men
The NHS uses the same BMI categories for women and men, so a BMI of 27 is overweight whether you are male or female. What differs is body composition: at the same BMI, women usually carry more body fat than men, and men tend to carry more fat around the waist.
BMI 27 for a woman
A 5′4″ (163 cm) woman with a BMI of 27 weighs about 71.3 kg (11 st 3 lb). To reach a BMI of 24.9 she would need to lose about 5.5 kg (0 st 12 lb). After the menopause, fat tends to move towards the waist, so a waist check is especially useful.
BMI 27 for a man
A 5′10″ (178 cm) man with a BMI of 27 weighs about 85.4 kg (13 st 6 lb). To reach a BMI of 24.9 he would need to lose about 6.6 kg (1 st 1 lb). Very muscular men can have a high BMI without excess fat, which is why waist size matters too.
Is BMI 27 different by age? No – adult BMI categories are the same from 18 onwards. Over 65, a BMI between about 23 and 28 is not usually a concern, and losing weight without trying should always be checked by a GP. Children need a BMI centile instead.
Health risks at a BMI of 27
At a BMI of 27, your risk of type 2 diabetes, high blood pressure, heart disease and joint problems is higher than in the healthy range, although it is lower than in the obesity range. The good news is that the risk falls as weight comes down: losing just 5% of your body weight can improve blood pressure, cholesterol and blood sugar.
BMI cannot tell fat from muscle, so it is best used with a second measure. NICE recommends a waist-to-height ratio: keep your waist to less than half your height.
What to do next
- Set a first goal of 5% weight loss. That is about 3.6 kg for a 5′4″ woman or 4.3 kg for a 5′10″ man at this BMI.
- Aim for 0.5–1 kg (1–2 lb) a week with a daily deficit of about 600 kcal – use the calorie deficit calculator.
- Move more: build up to 150 minutes of moderate activity a week plus 2 days of strength exercise.
- Use free NHS support: the NHS Weight Loss Plan app, or ask your GP or pharmacist about local weight management services.
