Based on population trends, more than seven in every 10 people born between the early 1980s and mid-90s will be too fat by the time they reach middle age.
In comparison, about half of the “baby boomer” generation, born just after World War Two, were fat at that age.
Being fat as an adult is linked to 13 different types of cancer, says Cancer Research UK, who did the analysis.
The list includes breast, bowel and kidney cancer, but only 15% of people in the UK are aware of the link, according to the charity.
