But one 23-year-old is doing the complete opposite and force feeding herself - often through a funnel - in a bid to become the fattest person in the world.
Tammy Jung was once a healthy eight-stone teenager who wore skinny jeans, loved playing volleyball and going out with friends.
Tammy says force feed herself – often through a funnel to eat at least 5,000 calories a day.
The attention seeker who currently weighs about 224LBS, says her boyfriend of eight months, Johan Ubermen,28, helps her gain weight by pouring ice cream milkshakes made with heavy whipped cream and a whole tub of ice cream down her throat through a funnel.
Tammy is somewhat able to finance her disgusting eating habit by selling pictures of her weight gain process on her Twitter site, Tammy Jung @SexySignature
