 Since the 1980s , several parties , including the Center for Science in the Public Interest ( CSPI ) , the British Heart Foundation , the City of New York , and the Spanish government , have argued that Burger King has contributed to obesity and unhealthy eating behaviors in Western nations by producing products that contain large amounts of salt , fat , trans @-@ fat and calories . After its purchase by TPG Capital from former parent company Diageo in 2002 , the company introduced several large , over @-@ sized products including its European BK XXL line , the British Angus burger six @-@ pack , the Enormous Omelet Sandwich line and the BK Stacker line . These new offerings , and others like them , have resulted in further international scorn and negative attention due the large portion size and increased amounts of unhealthy fats and trans @-@ fats in these items . Many consumer groups have accused Burger King and other fast food restaurant chains of failing to provide healthier alternatives .
