Recent research has found that being overweight appears to pose a greater risk of development of cirrhosis of the liver in men than alcohol consumption does.
Conducted by the Sahlgrenska Academy, the study found that two per cent of the men it monitored were diagnosed with cirrhosis of the liver after being monitored for 40 years.
None of the 855 men, who were aged 50 to begin with, had the condition at the start of the study.
However, all of those diagnosed by the end of it had been overweight initially, with an average body mass index of 28.
But the researchers noted that no such link could be proven in regards to alcohol consumption.
Jerzy Kaczynski, docent at the academy, commented: "A liver that has been ill and weakened as a result of overweight can take less of a load.
"We can therefore speculate that cirrhosis of the liver will develop more quickly in people who drink too much alcohol if they are overweight. Our study does not offer any evidence for this, but this kind of speculation is well founded."
