Is obesity a disease?
It's a disease, physical and in some cases mental.
No, it's not a disease.
I consider it an addiction, or several, so yes.
Not in and of itself but is often the result of disease. It's also the sign of psychological problems. A lot of people, especially women, use body fat to hide behind. Generally these women were molested as children and do not want to be sexual.
It's lack of self discipline.
Then what is it?
It's not a disease, it's a weakness.
