General Obesity Facts
The prevalence of overweight and obesity is indicated by body mass index (BMI)as a measure of general obesity and is calculated as weight(kg) / height(m2). The categories are:
BMI < 18.5 Underweight
BMI 18.5 to < 25 Normal
BMI 25 to <30 Overweight
BMI > 30 Obese
Obesity is associated with heart disease, cancer, disability during older age and decreased life expectancy as well as serious chronic conditions such as Type 2 diabetes, hypertension and Hyperlipidaemia (high levels of fat in the blood that can lead to narrowing and blockages of blood vessels).
Obesity is responsible for more than 30,000 deaths in England each year and will shorten the lifespan of a person by up to 10 years. It is preventing many people from reaching their retirement age.
You will have an increased chance of developing these diseases if you are obese:
- 3 times more likely to develop colon cancer
- More than 2.5 times more likely to develop high blood pressure
- Increased risk of heart disease
- At least 28 times great risk of developing diabetes
A high or very high waist circumference is associated with increased health risks. A high waist circumference is defined as being more than 102cm (40”) in men which can translate to XXXL in some clothes shops in the UK, and more than 88 cm (34”) in women. In the UK 32% men and 44% women have a raised waist circumference.
2017 Adult Obesity Statistics

- In 2013, about one in four of the adult UK population was obese, 26.0% of men and 23.8% of women. This is a marked increase from the 1993 figures of 13.2% for men and 16.4% for women
- The percentage of the population classed as overweight (including obese) has increased from 57.6% (1993) to 67.1% (2013) in men and from 48.6% to 57.2% in women.
- The worldwide prevalence of obesity has more than doubled between 1980 and 2014. ( http://www.who.int/mediacentre/factsheets/fs311/en/)
- In 2014, more than 1.9 billion adults, 18 years and older, were overweight. That's 39% (38% of men and 40% of women) of the world's adult population

- Overweight and obesity are the fifth leading risk for global deaths. At least 2.8 million adults die each year as a result of being overweight or obese.
- 44% of diabetes cases, 23% of ischaemic heart disease cases and between 7-41% of certain cancer cases are attributable to overweight and obesity.
2013-2015 Childhood Obesity Statistics
- The number of children who are obese is growing and has more than tripled in England over the past 25 years
- The proportion of obese children leaving primaryhas been steadily increasing from 17.5% (2006/07) to 18.9% (2012/13) to 19.1% (2015) ( http://www.who.int/mediacentre/factsheets/fs311/en/)
One plan by the authorities to reverse this childhood obesity trend is for councils to ban food takeways in a bid to stop children eating junk food. Read Dr Ashton's thoughts on this radical plan
