I have zero evidence. From personal experience from the women I know that have made themselves look like those in the video, they have not done so in a healthy manner. One girl I know used to starve herself. She would eat four or five crackers a day, and some water, and once in a while a banana. As for fat chicks, its not my style.I wont lie, I dated a few that were bigger, and they were lazy as shit and extremely insecure.I am the furthest thing from lazy and I do prefer them over 100 lbs.
