Obesity is a chronic and complex condition that can have significant impacts on people’s health, life expectancy, and quality of life, not to mention the wider effects on society and the economy.
By 2040, it’s estimated that more than 70% of people across the UK could be classed as overweight or obese, if current trends continue. This suggests a significant health issue that is unlikely to be resolved in the near future.
With this in mind, our weight loss experts have compiled the latest report for 2025, highlighting how obesity statistics are evolving in the UK, the current state of childhood obesity statistics, and what the future may hold in terms of ongoing obesity trends.

UK obesity statistics
The NHS estimates that around 25% of UK adults, and around 20% of children aged 10 to 11, are living with obesity.
For most adults, those with a BMI of 30 or above are considered obese, while those 40 and above are categorised as severely or morbidly obese.
General classification of BMI groups
BMI (kg/m²)
Definition
Less than 18.5
Underweight
Between 18.5 and 24.9
Healthy weight
Between 25.0 and 29.9
Overweight, but not obese
30.0 or more
Obese
40.0 or more
Morbidly obese
(Source: NHS England)
This is adjusted for people from specific backgrounds, such as Asian, Chinese, Middle Eastern, Black African, or African-Caribbean. For these groups, those classed as obese tend to have a BMI of 27.5 and above.
Note: BMI can help to determine the amount of weight you’re carrying, but doesn’t necessarily indicate where/how this is stored (i.e., muscle, water, bone). Therefore, some (like professional sportspeople) could theoretically have a high BMI despite a low body fat percentage. However, for most people, BMI is generally considered a good indicator of a healthy weight.
Prevalence of obesity in the UK
Prevalence of obesity in England
As of 2023-24, almost two-thirds (64.5%) of adults aged 18 and over in England were estimated to be overweight or living with obesity. This represents a 0.5% rise from the previous year and a 3.3% increase from 2015-16.
Furthermore, the proportion of adults in England living solely with obesity in 2023-24 was just over a quarter (26.2%), an increase of 3.6% in eight years.
Headline figures from the Office for Health Improvement and Disparities also show that, in 2023-24, the prevalence of overweight (including obesity):
Was higher among males than females (69.7% vs. 59.2%). Yet, for obesity alone, the figure was higher for females (26.9% vs. 26.2%).
Increased with age up to 64 years old, peaking at 73.5% and 32.5%, respectively, before decreasing in the older age groups.
Had a 34.6% gap between areas of most and least deprivation, ranging from 42.6% to 77.2%. The respective figures for obesity prevalence varied from 11.0% to 37.9% (a 26.9%).
Remained the highest among those from the Black community (73.4%) compared to 65.7% for those who identify as White British. Comparative figures for the prevalence of obesity stood at 33.1% and 27.8%, respectively.
Percentage of people in England living with obesity vs. other weight classifications by age group
The most recent obesity statistics from NHS England show that more than a third of adults (34%) are considered overweight, with a quarter considered obese (25%), and less than one in 25 categorised as morbidly obese (3%).
Findings from the 2022 NHS Health Survey indicate that:
Obesity rates in England tend to increase with age, rising from just over one in 10 for those between 16 and 24 (12%), up to almost one in three (32%) for the 65 to 74 year old bracket (an increase of 20%).
The proportion of adults considered overweight generally increases with age, from just one in four (23%) of those aged 16-24 to two in five (40%) for those over 75 (a rise of 27%).
More than half of those in the 16-24 cohort (54%) have a healthy body weight. This figure tends to decrease with age, down to a quarter (25%) of those between 55 and 64 years old (a 29% drop).
Mean average BMI in England by age group
Generally speaking, average BMI tends to increase with age, from 24.3kg/m² for those between 16 and 24, up to almost 29kg/m² for the 55-64 age bracket (a rise of nearly 20% over their lifetime).
Once someone hits their mid-60s, their average BMI tends to drop - down to approximately 27.5kg/m² by the time they exceed 75.
Did you know? To qualify for weight loss medication, you must meet specific criteria. One of which is an appropriate BMI. For more information, refer to our guide on the recommended BMI for weight loss medications.
Percentage of people in England living with obesity vs. other weight classifications by region
The latest statistics on obesity from NHS England suggest that around seven in 10 adults in Yorkshire and the Humber (81%) are overweight or living with obesity (the most of any region). This is in contrast to just over half of those in London (55%), a difference of 1%.
Percentage of people in England living with obesity vs. other weight classifications by level of deprivation
Recent obesity stats indicate that, as an area becomes more deprived, the proportion of adults considered overweight or obese tends to increase.
For example, just under three in five living in the most deprived parts of the country are considered to be overweight or living with obesity (59%), compared to almost seven in 10 in the most deprived neighbourhoods (68%). This represents a 9% difference.
Prevalence of obesity in Scotland
Obesity statistics from the Scottish government show that almost a third (32%) of adults in 2023 were living with obesity, a rise of 23% in just two decades.
According to the 2023 Health Survey:
Two-thirds of Scottish adults are classed as overweight (including obesity), a figure that has remained stable since 2008.
The mean adult BMI in 2023 was 28.0kg/m² (a figure that has remained unchanged since 2021), representing a 3.3% rise from 2003.
57% of those aged 16-24 are defined as having a healthy weight, compared to a range of 23% to 39% for other age groups.
Younger adults aged 16 to 24 recorded an average BMI of 25.5kg/m² (compared to a range of 27.7kg/m² and 29.2kg/m² for those aged 25 and above).
Mean average BMI in Scotland by age group
As adults in Scotland age, their average BMI tends to increase.
For example, those aged 16-24 had an average BMI of 25.5kg/m² in 2023. This figure reached 29.2kg/m² for a typical 55-64 year old (a rise of 14.5%).
The average BMI in Scotland tends to decrease after age 64, reaching 27.7kg/m² for those older than 75.
Prevalence of obesity in Wales
According to the most up-to-date statistics on obesity from the Welsh Government:
25% of men and 27% of women were reported as being obese in 2022/23, with 65% of men and 57% of women regarded as being either overweight or obese
Obesity statistics were highest in the 45-64 age group (31%) and lowest in the 16-24 and over 75 age groups (19% and 17%, respectively).
People without disabilities were more likely to report a healthy weight than those without (42% vs. 31%).
48% of Asian communities reported a healthy body weight compared to 34% from the Black community and 38% from those who identify as White.
Percentage of people in Wales living with obesity vs. other weight classifications by age group
In 2022/23, more than two in three of those living in Wales between the ages of 45 and 64 were considered overweight or obese (68%). This was followed by nearly three in five adults under 44 (57%) and those over 65 (59%).

At the other end of the scale, just over half of those in Powys (53%) and Monmouthshire (54%) fell into these categories, making them the least overweight/obese local authorities in Wales as of 2022/23.
Prevalence of obesity in Northern Ireland
According to the latest government report on obesity:
Approximately 28% of adults in Northern Ireland were classified as obese in 2023/24, with a further 37% considered overweight
69% of men were classed as overweight or obese, compared to 59.5% of women
Obesity levels were highest in those aged 45 to 54 and 65 to 74, with more than a third in these age groups defined as obese.
Obesity rates stood at 23.4% in 2010/11 (a rise of 4.2% in the space of nine years).
Of those who were regarded as overweight in 2023/24, 42.6% of women reported trying to lose weight, compared to 31.6% of men.
Percentage of people in Northern Ireland living with obesity
Obesity statistics from the Department of Health indicate that almost two-thirds of adults (65%) across Northern Ireland were regarded as overweight or living with obesity in 2023/24.
Percentage of people in Northern Ireland with obesity by age group
Obesity levels in Northern Ireland tend to be highest in the mid to older age brackets, with more than a third of those aged 45-54 and 65-75 considered to be obese (34% vs. 35%, respectively).
By contrast, in 2023/24, around one in seven adults (14%) aged 16-24 were defined as obese, roughly half the proportion compared to those aged 75 and above.
UK obesity rate over time
Between 1993 and 2022, the proportion of people in England diagnosed with obesity almost doubled, from 14.65% to 27.72%.
More than three-fifths (63.6%) are made up of people with Class I obesity (i.e., a BMI between 30.0 and 34.9).

Should current trends continue, our forecasts suggest that by 2030, around three in 10 people (30.31%) in England could be regarded as obese.
The bulk of these should still be made up of people with Class I obesity. However, the proportion with Class II obesity is expected to almost triple from 2.77% to 8.07% and be five times greater for Class III obesity (0.97% to 3.84%).
Rising obesity figures aren't as surprising when you look at how our lifestyles have changed. We're less active than ever - many of us spend hours sitting at desks or on sofas. Portion sizes have grown dramatically, ultra-processed foods are everywhere, and sugary drinks have become daily habits for many people.
What worries me most is seeing more people moving into the higher obesity categories. It significantly increases the risk of diabetes, heart disease, and joint problems. The good news is that small changes really do make a difference.
Start with simple swaps - water instead of fizzy drinks, taking the stairs, or adding a 20-minute walk to your day. Cook more meals from scratch when you can and watch your portion sizes. You don't need a dramatic diet overhaul – just consistent, sustainable changes.

Between 2001 and 2010, the proportion of people with Class III obesity grew by almost two-thirds (64%), the most significant growth across all obesity classes during this time.
By 2030, the percentage of people with class II and class III obesity is projected to grow by a fifth (20%) from 2020 figures.
Note: Obesity classes I, II, and III are differentiated by Body Mass Index (BMI) scores and indicate an increasing severity of obesity. Class I obesity ranges from a BMI of 30.0 to 34.9, Class II from 35.0 to 39.9, and Class III, also known as severe or morbid obesity, is a BMI of 40 or higher.
Mean average BMI in England over time
The most recent data from NHS England shows that the average BMI in 2022 was 27.6kg/m², representing a rise of almost 3% in 20 years.

Just over a quarter of men in England (26.4%) were considered obese in 2022, compared to almost three in 10 women (29.03%). These figures have approximately doubled since 1993, when the respective figures stood at 13.26% for men and 16.19% for women.
Our forecasts indicate that, if current trends continue, 29.78% of the male population and 31.9% of the female population in England could be considered obese by 2030.
Almost seven in 10 men (69.5%), and just under three in five women (58.3%), classified as obese in 2022 had Class I obesity (i.e., a BMI between 30.0 and 34.9). These figures are expected to remain broadly similar by the decade's end.

Our analysis of NHS England data shows that:
The proportion of males with Class III obesity (i.e., a BMI of 40 or more) almost doubled between 2001 and 2010, compared to females, who increased by approximately half.
By 2020, the percentage of males with Class III obesity had grown more than a third (35%) compared to 2010, a trend expected to continue as we approach 2030 (34%). The percentage change for females in this category over this time is relatively small by comparison (8% and 14%, respectively).
The proportion of females with Class II obesity (i.e., a BMI between 35.0 and 39.9) is predicted to increase by almost a quarter (24%) between 2020 and 2030, compared to nearly a sixth (15%) for males.
“There are differences between men and women when it comes to weight and obesity. Men tend to carry more weight around their middle - what we call 'apple-shaped' – whilst women often store it around their hips and thighs, which affects health risk differently.
Men's belly fat increases heart disease risk more directly, whilst women face different challenges, especially after menopause when hormonal changes make weight gain easier.
Women naturally have more body fat for reproductive reasons, and their metabolism often slows more with age. Men typically have more muscle mass, which burns calories faster, but they're also more likely to ignore weight gain until it becomes a serious health issue.
When it comes to weight loss, one size definitely doesn't fit all. My advice? Don't compare your journey to others, especially across genders. Work with your healthcare provider to find an approach that suits your body, lifestyle, and circumstances. What works brilliantly for your partner or friend might not be right for you, and that's perfectly normal.”

The most recent obesity stats for Scotland show that, in 2023:
Approximately two-thirds of males and females registered a BMI of at least 25 (67% vs. 65%, respectively).
More than a third of women (34%) and three in 10 men (30%) had an average BMI of 30 or above.
The proportion of females classed as morbidly obese (i.e., a BMI of 40 or more) was around double that of the male population (6% vs. 3%, respectively).
For Scottish males and females, the most significant growth was observed among those with a BMI of 30 or more, each increasing by 8% over the course of two decades.
Incidentally, the proportion of females classed as morbidly obese doubled between 2003 and 2023, compared to males, which stayed broadly the same over this time.

As of 2023, the average BMI for females in Scotland stood at 28.3kg/m², compared to 27.8kg/m² for males.
Both have seen an increase in typical BMI figures over the previous 20 years, rising by almost 3% for males and approximately 4% for females.
Percentage of males vs. females in Wales living with obesity
The latest statistics on obesity from the Welsh government indicate that:
59% of males aged 16 to 44 are classed as overweight or living with obesity, compared to 56% for females of the same age.
Just over three-quarters of males between 45 and 64 (76%) fall into the overweight or obese category (a figure that is contrasted by roughly three-fifths (61%) of females).
Almost two-thirds of males over 65 (64%) are judged to be either overweight or obese, compared to more than half of females in this age bracket (55%).
Percentage of males vs. females in Northern Ireland living with obesity
Obesity stats from the Department of Health indicate that, as of 2023/24,:
More than a quarter of males in Northern Ireland (28%) are classed as obese, compared to a fifth of females (20%).
The proportion of females deemed morbidly obese is three times higher than that of men (6% vs. 2%, respectively).
Two in five males (40%) are categorised as overweight, compared to just over one in three females (34%).
What is the estimated cost of obesity for the UK economy? It’s estimated that obesity costs the NHS around £6.5 billion every year. Should current trends continue, this figure is projected to reach £9.7 billion by 2050 (a rise of almost 50% in the space of 25 years).
The relationship between physical activity and obesity
When it comes to non-occupational activities, approximately two-thirds of working adults (between 66% and 69%) complete at least 75 minutes of heavy housework per week, apart from the 16-24 cohort, where this figure stands closer to four-fifths (82%).
This is contrasted by at least 90% who walk more than 75 minutes a week, making it the most popular physical activity for males outside of working hours.
Participation in sport for more than 75 minutes a week also tends to increase after the age of 44, dropping from around four-fifths (79%) for those aged 35-44 to more than 90% for the over 75s.

Roughly half of the male population aged 25 to 54 spends at least seven hours a day standing or sitting as part of their job, a figure that drops to just over a third of the 55-64 cohort (34%) and around a fifth of those aged 65-74 (22%).
In addition, between 75% and 80% of working males spend at least an hour a day climbing stairs or ladders, with between 16% and 21% walking around for one to three hours whilst at work.

NHS England’s Health Survey shows that:
Between 65% and 71% of females aged 25 to 74 complete at least 75 minutes of heavy housework per week, contrasting with around 75% to 76% of those aged 16-24 and 75 years and older.
At least 90% of those surveyed complete at least 75 minutes a week of heavy manual work, gardening, DIY, and walking.
The proportion of females standing or sitting at work for more than seven hours tends to decrease with age after 34, falling from just under half (49%) for those aged 25-34 to 16% for those aged 65-74.
The percentage of females who climb stairs or ladders for at least an hour a day as part of their job decreases from 82% among those aged 16-24 to 70% for those aged 65-74.
The relationship between levels of physical activity vs. obesity rates for males and females
Our analysis of NHS England data highlights several patterns when it comes to levels of physical activity amongst men and women and the resulting obesity statistics:
The strongest positive correlation was found between males and heavy manual work, gardening, and DIY (r = 0.92), indicating that engaging in these activities for less than 75 minutes a week is generally insufficient to prevent obesity.
For females, those who climb stairs or ladders for less than an hour a day probably aren’t doing enough to reduce their chances of becoming obese.
The strongest negative correlation was for women who lift, carry, or move heavy loads for 1-3 hours per day whilst at work. A score of -0.76 indicates that performing this activity over time has a greater benefit in reducing the risk of obesity than any other activity in the study.
The data really highlights something we've known for a while – not all exercise is equal when it comes to weight management.
For women, the data shows that those in roles like primary school teaching and social workers, that involve a lot of physical activity are linked to lower obesity rates. For men, it's construction, skilled trades and emergency services.
These aren't just burning calories – they're building muscle, which burns more energy even when you're resting. That's why a quick walk, whilst good for your heart, might not shift weight as effectively as resistance training.
Mix it up. Yes, walking is brilliant and everyone should do it, but add some strength work too. You don't need a gym – carrying shopping bags, gardening, or even vigorous housework all count.
Remember, the best exercise is the one you'll actually do. Find something you enjoy, whether that's dancing, swimming, or playing with the kids. Consistency beats intensity every time, and small changes like taking the stairs or parking further away really do add up.

UK childhood obesity statistics
Childhood obesity statistics in England
According to childhood obesity statistics from NHS England, there were 52,084 children in 2023/24 registered as living with obesity. Approximately 15.1% of these were situated in London, the most of any region, followed closely by the South East (14.6%)
Between 2017/18 and 2023/24, the number of children with obesity dropped by around 7%.
Our analysis of long-term childhood obesity data suggests that this decrease is likely to continue, with a further 7% decline by 2030/31.

* Forecasted data ** Data was not reported, so forward fill was used from 2019/20
By 2030, there could be 50,225 obese children across England, a decrease of around 7.1% in 13 years.
During this time, London is projected to experience the most significant decline in its childhood obesity population, with an estimated drop of 18.6% by the end of the decade. However, the number of children in the East of England living with obesity is forecasted to remain roughly the same in the coming year, with mild fluctuations.
Percentage change in childhood obesity statistics in England between 2020 and 2030 by region
Our forecast analysis suggests that, despite an overall downward trend from 2023/24, the proportion of children in England with obesity could be 27% higher in 2030/31 compared to the 2020/21 figures.
During these 10 years, the North West is expected to see the most significant percentage increase at more than three-fifths (63%), with London seeing the smallest percentage growth (2%).
Parts of England with the highest and lowest number of children living with obesity
As of 2023/24, more children with obesity lived in Kent and Birmingham than in any other area of England. A cumulative total of 3,075 represented approximately 5.7% of the overall total.
The number of obese children in Kent (1,540) was almost double the total amount for the nine lowest areas of the country put together.
At the other end of the scale, Rutland had the fewest number of children in 2023/24 living with obesity at 30. This was almost 50% less than the recorded figures for Kensington and Chelsea in West London.
Parts of England with the most and least significant percentage change in childhood obesity rates between 2020 and 2030
By 2030/31, childhood obesity rates in Shropshire and Surrey are predicted to be over three times greater than in 2020/21.
However, several areas in England are forecast to experience a decline in the number of children living with obesity between 2020/21 and 2030/31.
The most significant decline is likely in Brent, falling by almost 100% in 10 years, followed by Kensington and Chelsea at nearly three-quarters (-72%).

* Forecasted data ** Data was not reported, so forward fill was used from 2019/20
Obesity statistics from NHS England show that, as of 2023/24, childhood obesity was most prevalent in the West Midlands. This was 2.5% greater than the East of England, which reported the fewest childhood obesity cases per capita.
Based on 2023/24 figures, should current trends persist, England is expected to see a 0.1% increase in the prevalence of childhood obesity by 2030/31.
The biggest rise is predicted to be in the North West, with a 0.9% increase over seven years.
Parts of England where childhood obesity is most and least prevalent
The most recent child obesity statistics from NHS England show that the condition is most prevalent in Hartlepool and Middlesbrough, where around one in seven children (14.1%) are registered as obese.
At the other end of the scale, approximately one in 25 children living in Wokingham (5.5%) is considered obese (the lowest rate across the country). This means children living in Hartlepool and Middlesbrough are almost three times more likely to be classed as obese compared to those in Wokingham.
Percentage change in the prevalence of childhood obesity in England by region over time
Between 2010/11 and 2020/21, Yorkshire and the Humber experienced the most significant percentage growth in child obesity prevalence across all English regions, at almost a sixth (15%). This was contrasted by London, which experienced a 10% decline in 2020 compared to figures from 10 years earlier.
Fast-forward to 2030/31, and the prevalence of childhood obesity in Yorkshire and the Humber, as well as the North East, could rise further by 10% and 5% in their respective regions.
Our estimates also suggest that London could experience the most significant decline in childhood obesity rates across all areas of the UK, at -11% between 2020/21 and 2030/31.
Parts of England where childhood obesity prevalence has increased and decreased the most over time
Our analysis of historical childhood obesity statistics suggests that areas of England where childhood obesity has become more prevalent are generally located in the north.
Between 2010/11 and 2020/21, cases of child obesity rose by two-thirds (66%) in Middlesbrough, the largest increase among all areas in the study. Gateshead followed, with a 50% increase over the same period.
However, most locations where childhood obesity has become less prevalent tend to be situated in the capital, accounting for nine of the top 10 places on the list. Hammersmith and Fulham experienced the most significant percentage decrease in child obesity levels between 2010/11 and 2020/21, with a reduction of almost a third (31%) in 10 years.
Parts of England where childhood obesity prevalence is expected to increase and decrease the most
Our predictions suggest that, by 2030/31, child obesity will be almost half as prevalent in the East Riding of Yorkshire as it was in 2020/21 (the most considerable rise across all parts of the country).
Of the top 10 locations expected to see a decline in the prevalence of childhood obesity between 2020/21 and 2030/31, the most significant decrease is anticipated in Wokingham, with a reduction of more than two-fifths (-44%) in the number of cases relative to its population. This is followed by Hammersmith and Fulham, with a predicted decrease in child obesity of almost a third (-32%) by the start of the next decade.
The regional differences in childhood obesity really come down to opportunity and resources. Areas with higher deprivation often have fewer parks, sports facilities, and outdoor spaces for children to play. Fresh, healthy food can be more expensive and harder to find, whilst fast food outlets tend to cluster in these communities. It's not about parents caring less – it's about having fewer options.
What's encouraging is that small changes at home can make a real difference regardless of where you live. Focus on what you can control.
Swap fizzy drinks and juice for water – that alone can cut hundreds of calories a day. Make screen time active time. Dance along to videos or do exercises during adverts. Cook together when you can; children who help prepare meals are more likely to eat them.
Most importantly, focus on health, not weight. If you're worried about your child's weight, speak to your GP or school nurse. They can provide support tailored to your circumstances and connect you with local resources you might not know about.

Prevalence of childhood obesity in England by gender over time (reception age)
As of 2022, less than one in 10 boys and girls of reception age were considered to be living with obesity. For boys, this represents a fall of 1.2% from the peak of 10.5% in 2009, and for girls, a decrease of 0.9% from a high of 9.9% in 2021.
Our forecasts suggest that the prevalence of child obesity across England is expected to remain essentially unchanged by the end of the decade, fluctuating between 9% and 10% in the coming years for both boys and girls.
Number of children living with obesity in England by gender over time (reception age)
The most up-to-date childhood obesity figures from NHS England show that in 2022, there were 13,934 children across the country classed as obese. Almost 54% of these were boys.
By 2030, the number of children in England living with obesity is predicted to rise by approximately 13.5%, with boys still occupying just over half of the overall total.
Note: The spike in 16,428 reported cases in 2021 can largely be attributed to the lack of data collected during 2020 due to the COVID-19 pandemic. Therefore, for forecasting purposes, 2019 figures were used for 2020 to prevent any gaps in the data.

According to our analysis of childhood obesity stats, the prevalence of childhood obesity in girls increased by 10% between 2010 and 2020, yet remained largely stable for boys.
By 2030, the number of girls living with obesity is predicted to increase by two-thirds (66%) and just over half for boys (52%), from 2020 figures. Yet, this translates to a fall of 5% in the prevalence of child obesity in boys across England and a 2% rise for girls.
Childhood obesity statistics in Scotland
According to the latest childhood obesity report from the Scottish government, based on their BMI, almost seven in 10 children are considered to have a healthy weight. Since 1998, this number has varied between 64% and 72%.
In addition, more than one in six children in 2023 were at risk of developing obesity in later life (17%), a figure that has fluctuated between 13% and 18% since 1998.
Percentage of children in Scotland at risk of obesity and being overweight over time (based on Primary 1 BMI)
Based on Primary 1 BMI figures, more than three-quarters of children in Scotland (76.5%) were classed as having a healthy weight in 2023/24, with just over one in 10 (10.5%) at risk of developing obesity.
This represents a respective rise of 6.6% and a decrease of 4.9% from the 2020/21 period. However, the figures for this year were likely under- or overreported due to the impact of the COVID-19 pandemic.
Percentage of children in different regions of Scotland at risk of obesity and being overweight (based on Primary 1 BMI)
Almost one in three children living on the Orkney Islands in 2023/24 (31.6%) were classed as overweight or obese (the highest proportion from any region in Scotland). This was followed by Angus, where more than one in four children (27.6%) fell into either of these categories.
At the other end of the scale, just over a fifth of children in Falkirk (20.9%) were deemed to be overweight or obese in 2023/24, the lowest percentage across all Scottish regions for the year.
Percentage of children in Scotland at risk of obesity and being overweight by level of deprivation (based on Primary 1 BMI)
According to child obesity stats from Public Health Scotland, the risk of obesity in children tends to increase as an area becomes more deprived.
As of 2023/24, around one in seven children living in the most deprived neighbourhoods in Scotland (14.0%) were considered to be at risk of becoming obese. This was more than half the proportion compared to those living in the least deprived areas of the country (6.4%).
However, just over seven in 10 children from the most deprived parts of Scotland (72.0%) had a healthy body weight in 2023/24. Yet, this figure rose to more than four in five (+10%) for the areas with the least amount of deprivation (82.0%).
Childhood obesity statistics in Wales
The latest childhood obesity statistics from Public Health Wales indicate that almost three-quarters of children across the country have a healthy weight (73.5%), with nearly one in eight considered at risk of developing obesity (11.8%).

The proportion of children at risk of becoming obese has fallen in recent years, by 0.8% from 2018/19. However, a lack of reported data between 2019 and 2022 means that national figures are starting to stabilise following the COVID-19 pandemic.
Percentage of children in different parts of Wales living with obesity
On average, across Wales, virtually one in four children is either overweight or obese (25.5%). This figure rises to almost three in 10 for those living in Hywel Dda (29.3%) and drops to just over one in five children from the Cardiff and Vale area (20.9%).
Percentage of children in Wales at risk of obesity and being overweight by level of deprivation
Like many other parts of the UK, as deprivation levels increase in Wales, so does the percentage of children at risk of becoming obese.
For example, just over one in seven children living in the most deprived neighbourhoods are likely to be obese in the future (14.6%), compared to less than one in 10 residing in the areas of least deprivation (8.4%).
Did you know? According to a government report, one in three children in Wales is considered overweight or obese by the time they start primary school.

As of 2023/24, nearly three-quarters of children in Northern Ireland were considered to have a normal body weight (74.62%), with around one-sixth rated as overweight (15.49%) and just over one in twenty deemed to be obese (5.83%).
Percentage of children in Northern Ireland living with obesity and overweight over time
These figures have remained the same over the previous decade, with minor fluctuations and a lack of reported data between 2019 and 2021 due to the COVID-19 pandemic.
That said, the proportion of children classified as obese has dropped slightly (0.27%) since 2021/22.

Recent child obesity statistics reveal slight variations across different areas in Northern Ireland.
With a difference of 1.49% between Belfast and the South Eastern region, each part has around one-fifth of its child population categorised as overweight or obese, ranging from 20.60% in the South Eastern region to 22.09% in Belfast.
Percentage of children in Northern Ireland classed as overweight or obese by local authority
When broken down by local authority, almost a quarter of children living in Newry, Mourne and Down in 2023/24 (23.62%) were deemed to be overweight or obese (the highest percentage figure across all local authorities in Northern Ireland).
That said, just over one in six children from Lisburn and Castlereagh (17.89%) were classed as overweight or obese in 2023/24, a difference of 5.73% compared to Newry, Mourne and Down.

As with most other parts of the UK, the percentage of overweight/obese children in Northern Ireland tends to fall as levels of deprivation within an area decrease.
For example, just under one in four children from the most deprived neighbourhoods in Northern Ireland (24.67%) were considered overweight or obese in 2023/24. This figure drops to just over one in six (17.75%) for those with low levels of deprivation (a decrease of 6.97%).
Obesity and diabetes statistics
Obesity and type 2 diabetes statistics in the UK
According to Diabetes.co.uk, the UK has the highest level of adult obesity in Western Europe, with around 26% classed as obese and an additional 38% categorised as overweight. In all, this means almost two-thirds (64%) of UK adults are carrying excess body weight.
These numbers are just as concerning for children, with around one in three aged between 10 and 11 defined as being overweight or living with obesity.
By 2040, forecasts suggest that more than seven in 10 UK adults could be overweight or obese unless action is taken.
The latest diabetes statistics suggest that between 80% and 85% of those with type 2 diabetes are overweight or obese. Research shows that people with obesity are up to 80 times more likely to develop type 2 diabetes than those with a BMI of less than 22.
The good news is that obesity is treatable; a 5% reduction in body weight can improve insulin sensitivity, lower blood pressure, and reduce cholesterol levels. Overall, this could reduce your chances of developing type 2 diabetes by more than 50%.

The latest NHS England data shows that around one in 10 people regarded as obese have also been diagnosed by their doctor as having diabetes.
This figure drops by around half for those defined as overweight.
The link between obesity and mental health has been a topic of medical discussion for decades, dating back to a pioneering 1976 study by Crisp and McGuiness, who found that men living with obesity reported loweranxiety and depression than those with a healthy body weight. There were also significant differences in anxiety levels for women, but not depression.
However, contrary to these outcomes by Crisp and McGuiness, developments in our understanding of the link between obesity and mental health now suggest that depressive symptoms and clinical depression tend to increase in populations living with obesity.
A 2022 study by Frank et al found that individuals regarded as obese were between 18% and 55% more likely to develop depression than those not living with obesity. They also discovered that the chance of being diagnosed as obese increased by 37% to 58% for those who had clinical depression.
Furthermore, a multicohort study of more than 240,000 people from the UK and Finland in 2023 concluded that those with moderately severe to severe depression were around seven times more likely to be hospitalised due to obesity than those without depression.
Did you know? Living with obesity can cause sleep apnoea (a potentially serious condition where your breathing can stop during sleep). Weight loss injection statistics show that using this type of medication could result in an average of 25 fewer breathing problems per hour.
It should be acknowledged that the long-term effects of weight change on mental health remain unclear, with more needed to understand the impact of weight loss on rates of depression over time.
Initial evidence from the Tasmanian Longitudinal Health Study (2023) suggests that weight gain in childhood to mid-adulthood comes with a higher risk of depression in later life. However, further studies are required here to better understand the obesity-depression link, particularly the impact of intentional weight loss on people’s psychological well-being.
In addition, a study of men and women aged 50 and above in England found that 24.2% of those with class II obesity (i.e., a BMI between 35.0 and 39.9) reported experiencing discrimination, compared to 35.1% of those with class III obesity.
Experiencing stigma and discrimination can internalise the situation. Those with a high body weight may perceive themselves to blame for their condition, thus increasing the risk of developing a negative body image. This can undermine self-confidence and self-esteem, and lead to poor/decreasing mental health.
A consequence of this could be overeating. A meta-analysis of 105 cross-sectional studies found an association between perceived weight stigma and rates of depression, anxiety, psychological distress, and an overall reduction in quality of life.

Rindler et al discovered that those classed as overweight, obese, or even underweight tend to show significantly decreased levels in their quality of life compared to those with a ‘normal’ body weight.
They found that the link between levels of obesity and a negative quality of life was almost twice as significant for those defined as obese compared to those who were overweight. Rates of depression for the obese population were also around three times higher than those classified as overweight.
Did you know… According to research, there could be up to 11 different types of obesity, each with distinct biological characteristics. Scientists from across the globe analysed the DNA of two million people to investigate the possible link between genes and obesity.
By analysing genetic patterns (such as waist and hip size and fat distribution), they discovered 743 genetic loci involved in body shape and size (86 of which were previously unknown).
This suggests that obesity is highly polygenic, meaning that multiple genes likely play a role in the overall process. In essence, this means two people could have the same BMI and appear equally obese, yet the reasons for their weight gain could be completely different.

How many people die from obesity in the UK?
Analysis by the British Heart Foundation suggests that around 31,000 heart and circulatory deaths occur in the UK each year due to excess weight and obesity. This equates to approximately 85 deaths per day from heart attacks or strokes that are linked to having a BMI of 25 or higher. In all, they concluded that 53% of all deaths from having a high BMI can be attributed to heart and circulatory diseases.
Chemist4U sought to gather historical obesity statistics and forecast them for future years.
To achieve this, exponential smoothing was employed, taking into account both seasonality and trends.
The percentage change was then calculated to determine which local authorities and genders were likely to experience the most significant shifts in obesity statistics in the future.
Note: As health services are devolved in the UK, each nation (i.e. England, Wales, Scotland, and Northern Ireland) reports on obesity slightly differently. This makes comparisons between the four nations difficult and has been avoided for this page.
In addition, the degree to which historical data was available for each nation varied in terms of recorded obesity statistics. Therefore, forecasting was only conducted for England, as this was the most comprehensive dataset available, enabling more reliable forecasting to occur.
The relationship between physical activity and obesity
Correlation coefficients were calculated between adult obesity and physical activities to find which activities have the most significant impact on obesity.
Data was taken from the most recent NHS Health Survey on the percentage of people from different age groups who completed various physical activities each week and the duration of those activities.
This was then correlated with obesity figures for those age groups to determine the strength of the relationship between the two and to ascertain which activities had a positive or negative correlation with obesity, as well as the strength of that relationship.
