She was way fatter and is losing weight. She published before and after pictures in the comments. You can see the fat was in her face. Now that she has lost a lot of fat the skin of her face is deformed and that is why she has the weird expression. On top of that it looks like she wasn't very pretty to start with, but she made it way worse and weird. Some fats get lucky that they get almost no fat in the face. Not this one, shell have this weird expression forever. She could try surgery but that has it sets of problems and lost of expression too.
