The idea of "healthy obesity" is a myth, research suggests.
Excess fat still carries health risks even when cholesterol, blood pressure and sugar levels are normal, according to a study of more than 60,000 people.
It has been argued that being overweight does not necessarily imply health risks if individuals remain healthy in other ways.
The research, published in Annals of Internal Medicine, contradicts this idea.
The study looked at findings from published studies tracking heart health and weight in more than 60,000 adults.
