The World Cancer Research Fund has claimed that keeping to a healthy weight could prevent more than 22,000 cases of cancer every year.
Watch those scales- having a BMI of over 30 is classed as being clinically obese
Excess body weight raises the risk of cancers of the pancreas, breast, bowel, oesophagus, kidney, womb and gall bladder.
Experts at the WCRF say that 123,000 cancer cases in the UK are attributed to weight each year. Of these, 18 per cent could be preventable, saving the lives of 22,000 people.
Professor Alan Jackson, professor of human nutrition at the University of Southampton and chairman of the CUP panel, said: "A significant number of cancer cases could be prevented by people maintaining a healthy body weight.
"Through keeping levels of body fat low, a lot of people will avoid getting cancer in the first place – forestalling the pain and anguish associated with the disease."
The latest report, called the Continuous Update Project (CUP), found that 1,257 cases of pancreatic cancer specifically could be prevented every year if patients were a healthy weight.
Pancreatic cancer is the fifth most deadly cancer in the UK, with most sufferers having a low survival rate. Professor Jackson said:
"Fewer than one in five patients survive the first year after diagnosis but we have found that 15 per cent of new cases could be avoided every year by keeping body weight within the healthy range."
According to research, 63 per cent of all Britons are either overweight or obese, with a BMI higher than 25 or 30.
A report in February revealed that the number of weight loss operations performed on the NHS in England rose by 12 per cent in a year.
