Haha, are you kidding me??  Look at the high contrast, to blur the general fatness of the features.  Look at the angle of the shoulders, clearly padded by excess fat.  Look at the slope of cheekbone into jawline, drooping slightly into a jowl shape with flab.  Look at the motherfucking CREASE between her fat chest and her fat neck!  All the signs were there; you were all but blind not to have seen them.
