What a BMI of 35 means
Body mass index (BMI) compares your weight with your height. A BMI of 35 means you weigh 35 kilograms for every square metre of your height. Using the NHS categories, a BMI of 35 is classed as obesity (class 2) for most adults.
Most adults
BMI 35 = obesity (class 2). 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 35 = obesity (class 2). NICE uses lower cut-offs of 23 and 27.5 because health risks start at a lower BMI.
Your BMI is 10.1 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 35 for women and men
The NHS uses the same BMI categories for women and men, so a BMI of 35 is obesity (class 2) 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 35 for a woman
A 5′4″ (163 cm) woman with a BMI of 35 weighs about 92.5 kg (14 st 8 lb). To reach a BMI of 24.9 she would need to lose about 26.7 kg (4 st 3 lb). After the menopause, fat tends to move towards the waist, so a waist check is especially useful.
BMI 35 for a man
A 5′10″ (178 cm) man with a BMI of 35 weighs about 110.6 kg (17 st 6 lb). To reach a BMI of 24.9 he would need to lose about 31.9 kg (5 st 0 lb). Very muscular men can have a high BMI without excess fat, which is why waist size matters too.
Is BMI 35 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 35
A BMI of 35 is in the obesity range. The NHS explains that obesity raises the risk of type 2 diabetes, coronary heart disease, stroke, some types of cancer (including breast and bowel cancer), fatty liver disease, osteoarthritis and sleep apnoea. Risks rise further at higher BMI levels and when weight is carried around the waist.
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 4.6 kg for a 5′4″ woman or 5.5 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 and whether you could be referred to a specialist service.
- Talk to your GP about medical options: NICE recommends weight loss medicines and surgery only at certain BMI levels and with specialist support. For example, surgery is usually considered at a BMI of 40 or more, or 35 or more with a related condition such as type 2 diabetes.
