According to the latest figures from the Child Measurement Programme, 657 Year Six pupils in Reading primary schools were classed as overweight or obese in 2019.
That is 34 per cent of all children in that age bracket – or more than one in every three children.
Of these, 14 per cent are classed as overweight and 20 per cent are obese.
Five per cent (87 children) are deemed to be severely obese with a Body Mass Index rating of 40 or more.
This is the equivalent of a 4ft 8ins boy – the average height of a 10-year-old – weighing nearly 13st.
The figures also cover younger children, and revealed more than a fifth of all Reception children in Reading, Berkshire, are also overweight or obese.
WATCH: How you can tell if your child is obese
According to the figures, 13 per cent are considered overweight and nine per cent obese.
More than one per cent of four- and five-year-olds are severely obese.
NHS chief executive Simon Stevens said: “Obesity is a dangerous public health threat for our children, leading to a string of serious illnesses.
“These figures show that, as a country, we are clearly not on track to meet the government’s sensible goal of halving childhood obesity.
“While the NHS will be there for patients, services and budgets will obviously be placed under more strain.
“So we also need combined action from parents, businesses and government to safeguard our children from this preventable harm.”
Elsewhere in Berkshire
Other parts of Berkshire also have an issue.
The figures show 15 per cent of children in Year Six and seven per cent of children in Reception have a BMI of 30 or more.
In Bracknell Forest , the figure is 16 per cent of 10 and 11 years and eight per cent of four and five years olds have the same BMI.
In the Royal Borough of Windsor and Maidenhead , 15 per cent of Year Six pupils and seven per cent of Reception pupils are obese.
And in Wokingham 14 per cent of Year Six children are deemed to be obese and seven percent of Reception age children.
Experts say obesity is strongly linked to deprivation, with the figures of children living in the poorest areas twice that of those in the least deprived.
