FIFA has told the Associated Press that obese fans will be offered special tickets at the 2014 World Cup in Brazil.
Under Brazilian legislation at least 1% of seats in each stadium are to be made available for people with disabilities, including those classified as obese.
FIFA confirmed it is the "first time tickets for obese people are offered at a FIFA event", with supporters from all nations entitled to the tickets, which will also be available for June's Confederations Cup.
"FIFA is generally following local legislation of the host countries, and is in Brazil guided by the General FIFA World Cup Bill and a separate decree related to obese people," football's governing body told the Associated Press.
"The number of tickets available for disabled people depends on the infrastructure provisions of each stadium and the distribution between seats."
FIFA said that to qualify for a ticket, people are required to submit a medical certificate that proves they have a body mass index of 30 or more, as recognised by the Brazilian Ministry of Health and World Health Organisation.
