Basically in the beginning, it's all about how models don't really watch their figures and eat basically whatever, supported by showing how calorie-dense the backstage food is.
But then Vlada Roslyakova answers about how are they fed during fashion week, first thing she says is that she drinks lots of tea, and she's very happy when there's tea there, as she doesn't like coffee. She says she eats a croissant here and there and she likes the sandwiches
The next models says they are fed crap at the backstage, so in the evening she tries to eat something healthy, soup for instance. Chanel says she tries to always bring her own food.
Then they ask if they see a change in their figure after eating food like that at shows. First model says no, but Vlada says she has to survive it for a month, but she tries to have a healthy breakfast like oatmeal or omelette, and the rest of the day is very random when it comes to eating. Snejana then says that it's okay and her stomach works somehow (on no food, I guess).
