This kind of restrictive eating is an eating disorder. She admitted to having an eating disorder in the SG early days and now she's thinner. It really pisses me off that people like her glamourise this kind of disordered eating, it makes people think it's normal and healthy, it's not. I feel sorry for her, but she should know better.
Also, I know people say she can't have an eating disorder as has had 4 healthy kids, I know someone with long term anorexia who not long ago had a healthy baby, this lady looked like a famine victim before and after pregnancy, EDs don't necessarily stop conception.
