She's so blessed with her good genetics. It would be incredibly easy for her to lose the weight, but it doesn't look like she's trying.
She's pulling a classic fat girl move and going EVERYWHERE in gym clothes hoping no one notices or at least that they'll think she's working on it.
Also... this might be a bit too much of a conspiracy theory notion... but notice how in a lot of these there are guys behind her way too obviously checking her out? I feel like this shit is staged just for more publicity.
