I don't think either of those women are big enough to suffer serious health problems due to their weight, but they're not healthy. Being healthy requires a certain amount of physical activity, an they're obviously not getting enough of that. If they were, they wouldn't be overweight in the first place.
I'm not touching most of this arguement, but that is untrue. You can be chubby and active, and you can be a skinny couch potato. There is always more than one factor in weight.
