"Aided by her 'feeder' boyfriend Johan, Tammy's daily diet includes up to 30 doughnuts as well as stacks of pancakes and waffles.
The couple can spend up to £70 a day on takeaways and junk food to fuel Tammy's mammoth appetite.
Tammy said: 'I start the day with a huge breakfast of waffles, cream cheese, bacon and sausage then head to McDonalds for a few burgers in the afternoon.
'I can snack on cheese all day, a couple of blocks is no problem, then for dinner I'll either eat pizzas or make Mexican food.
'At the end of the day I make a weight gain shake from heavy whipped cream and a whole tub of ice cream, which Yohan feeds me through a funnel.
'The funnel forces me to drink the shake even when I'm full after a day of eating.'"
