Some 30,000 Boys Scouts have descended on West Virginia for the annual National Scouts Jamboree.
But organizers said scouts with severe weight problems are not welcome.
The Boys Scouts of America said one of the requirements for this year is to have a body mass index below 40.
Organizers said it TMs not safe for obese children and adults to participate in the jamboree TMs physical activities.
Boy Scouts officials said the group offers plenty of summer camp experiences that do not have that requirement.
According to the Center Disease Control and Prevention in Atlanta, children with a body mass index of 32 to 39 are considered obese.
