Iona Spangenberg insists she's just unluckily skinny.  The Romanian-born model's waist measures at a startling 20 inches around, just 5 inches more in diameter than a compact disc.  She claims she eats three square meals and snacks on chocolate everyday.

Of her tiny physique 30-year-old Spangenberg says:

"No one seems to believe it, but every day I eat three big meals and I snack on chocolate and crisps all the time. I just have a small stomach, it's a bit like having a natural gastric band -- if I eat too much, I feel sick.  In Romania it is better to be overweight, because that means you are from a wealthy family. So while my friends were going out and dating, I was sitting at home with Mars bars wishing I could fatten up."
