This is disgusting. Poor kid."
I doubt she could be forced to eat 15 burgers, bottles of coke, chips etc... all in one go, I am willing to bet that Prader Willi syndrome is to blame, although the types of food she eats obviously does not help her weight which is why she needs a strict diet, it is possible to lose weight with this condition.
Don't forget she is only 7 years old, most 7 year olds don't eat alot anyway and at that young age her stomach would not that big unless she has a genetic defect, so she isn't just being 'forced' to eat this stuff. People with this condition can get very aggressive and abusive if they don't get food as their hunger cravings are alot more intense than the average person.
