I don't see the point here. It's not about somebody eating a lot, it's about being fat. Although I'm sure greasy food like that isn't good for you. People need to limit what they eat to what their body can handle. If top girl can eat all that and stay thin, that's fine. The girl in the lower picture can't and should probably go on a diet. Like I can eat a lot but my metabolism can handle it so it's fine. I burn a lot of calories.
I'm not going to sit here and fat shame but you have to remember that there is no such thing as healthy fat. Being overweight puts stress on your joints and organs.
It honestly makes me sad when people can't walk around a store without getting winded or worse, have to ride scooters because they can't support their own weight. We should never, ever encourage obesity.
