Obesity should be renamed to help people lose weight.
Researchers say those who overeat should be treated as if they have an illness called "chronic appetite dysregulation" so the stigma surrounding obesity can be removed.
Experts at University College Cork and the University of Galway in Ireland say that people in this situation should be regarded as suffering from a disease as it will make them more likely to seek professional help for the issue.
However, psychiatrist Dr. Max Pemberton argues that the move will take away "personal responsibility" to deal with obesity and suggested it is part of a trend to medicalise aspects of people's lives.
He said: "People who are overweight and want to lose weight should be met with compassion and support. But we can be kind and caring to people who are struggling without claiming they have a disease. Disease suggests there is an inevitability when it does not have to be that way."
