Obesity is a rapidly increasing problem across the globe. It is a problem no less prevalent in the UK. However, few understand the scope and severity of the problem.
In this article, we will break down some of the most recent and revealing statistics surrounding obesity and highlight how weight loss can significantly improve your health.
Some people don’t realise they’re overweight until it’s too late. That’s why there is a medical classification for weight.
Weight is measured by body mass index or BMI. Your BMI is calculated using your height and weight. It tells you how much you should weigh based on your height.
BMI is the primary way to diagnose those who are clinically overweight or underweight. It’s not an ideal tool for everyone.
For instance, if you do strength training, a BMI calculator will not factor in muscle mass which may give you unreliable results.
You can use the following formula to work out your BMI:
BMI = weight (kg) / (height (m))²
The formula will give you a value that will say whether your weight is healthy or not. There are also several tools online that will do it for you.
The BMI chart below shows the weight ranges based on BMI.
If you have a BMI of 40 or more, you are deemed morbidly obese.
According to the most recentin England, 25.9% of adults are obese and a further 37.9% are overweight but not obese.
Over 25% of UK adults are classed as obese.
Obesity rates in the UK are higher in men. 68.6% of men are obese or overweight, compared to 59% of women.
They also found that obesity rates increased with age. They found that almost three-quarters of people aged 45-74 in England are overweight or obese.
Several other factors can influence obesity rates.published by the Office for Health Improvement and Disparities show that:
These percentages have steadily increased throughout the years.
Obesity rates in England have risen dramatically throughout the years.
In 1993, the amount of people who were obese or overweight was 52.9%. The amount of people who were obese was 14.9%.
have predicted that obesity rates will continue to rise without serious intervention.
By 2040, 7 in 10 people will be classed as overweight or obese in the UK.
One analysis predicted that 21 million adults in the UK will be obese by 2040. It also predicted that the percentage of UK adults who are classed as overweight or obese will be 71% by 2040. That’s roughly 7 in every 10 people.
There is no clear answer to the rapid obesity rates across the globe.
One common hypothesis amongis that it is down to modernisation in the Western world. This theory is heavily debated.
We do know, on the other hand, that obesity has two core causes among individuals: eating too much and doing too little.
A balanced diet is important for healthy living. However, changing trends in UK diet culture have added to rising obesity rates.
All of these factors lead to poor diet and obesity.
Inactivity rates are contributing to our obesity.
Anfound that 22% of adults were considered inactive as they do fewer than 30 minutes of physical activity a week. Activity levels generally fall with age and sharply decrease at 75 and above.
Being overweight negatively affects your body in many ways. It puts you at a higher risk of a seemingly endless list of health problems such as heart conditions, diabetes, muscle and bone problems, cancer and many more.
Below are some statistics for the most prevalent obesity complications.
Obesity damages your heart and the rest of your cardiovascular system. It causes damage to your blood vessels and excess fatty deposits to build up.
This restricts your blood flow across your body and puts a strain on your heart muscle. It puts you at a higher risk of several cardiovascular conditions. Below are some obesity and heart disease statistics.
If you’re overweight, you areto have high blood pressure (hypertension). A estimated that 65-78% of cases of high blood pressure are caused by obesity.
Being obese also raises your risk of high cholesterol, blood clots, heart failure and other heart conditions. Damage and strain on the heart can result in cardiac-related death if left untreated, such as from a heart attack.
Research from the British Heart Foundation found that 31,000 circulatory disease-related deaths in the UK every year are associated with being overweight.
Obesity is one of the leading causes of diabetes. Excess abdominal fat causes a chemical reaction that means the body is less sensitive to insulin.
According to an 60% of people with type 1 diabetes are overweight or obese., 90% of adults with type 2 diabetes in the UK are overweight or obese. In addition, around
Being overweight does not guarantee cancer. But, a lot of evidence suggests it can put you at a higher risk of getting certain cancers.
Evidence compiled by Cancer Research UK suggests that more than 1 in 20 cases of cancer are caused by being overweight. A healthy weight can also significantly reduce your risk of 13 types of cancer.
For example, you areto develop endometrial cancer if you are severely obese. You are 2 times more likely to develop , and .
This is because excess fat on your body affects your body in several ways. It increases rates of growth hormones, inflammation and oestrogen. All of which can increase your rate of cancer cells developing.
Obesity can also impact your mental health.
Onefound that overweight people are at a 70% increased risk of developing mental health disorders.
A combination of factors can lead to mental health issues in obese people, including negative thoughts surrounding appearance (body dysmorphia), isolation from immobility and increased hormone levels.
Childhood obesity is also on the rise in the UK.
The most recentreported that 10.1% of children aged 4 - 5 and 23.4% of children aged 10 - 11 were obese.
They found that obesity rates were slightly higher in boys. This is most prevalent in ages 10-11 where there is a 6% difference.
There are several causes for these rates. The main cause is unhealthy eating.
The results of the most recentshowed that children of all ages exceeded the daily recommended sugar and saturated fat allowances but didn’t reach the recommendations for more beneficial nutrients such as fibre.

Children also have low activity rates. A recent Sport England Active Lives survey found that only 45% of young children meet physical activity guidelines of 60 minutes of physical activity a day.
Obesity is a huge strain on public healthcare. A recentfound that 1 million hospital admissions in England were linked to obesity in 2019 - 2020. This had increased by 17% compared to the previous year.
Obesity could cost the NHS over £9 billion by 2050.
These rising admission rates come at a cost.reported that the NHS spent over £6 billion on obesity and overweight-related health problems in 2017. They predict this number will have increased by over £9 billion by 2050.
Untreated obesity is a prevalent cause of death. The World Health Organisation estimates that at leastdie a year globally from being overweight or obese.
by the University of Oxford also found that moderate obesity can reduce your life expectancy by 3 years, whilst in those with severe obesity the figure is as high as 10 years. Other have found this number is as high as 14 years.
These statistics are scary but these health risks can be avoided if you lose weight.
Eating healthier food and introducing light exercise into your daily routine is the best first steps to healthy weight loss.
