Overweight since the day she could walk, the LA law student's wake up call finally came with a shock admission by her Dad that he was embarrassed to be seen in public with her.
Maddy told MailOnline:
"I used to weigh the same as a baby elephant. I wasn't living.At times I just wanted to die."One day my dad said 'I'm embarrassed to go out with you. Not because you're fat, because your weight shows people that you don't care about yourself and you don't value your body or life'.
My diet as a child was ridiculous."For example, in our culture we eat a lot of cow tongue."It's the most delicious way to get instant heart disease. When I was little I loved it and would eat two or three a day"I was six years old and eating over 2000 calories a day of fatty cow tongue."
Maddy's surgery was also painful, but a year on she is determined to keep the weight down.
She said: "The last six or so months have been all me exercising my willpower and self-control.'"I am happier, I am more confident, I am social, I am lively, I am nicer, I am more fun."
