Gaining weight

Harvey had no objections to being swapped into a new body by the Great Shift -- mostly because he got a fantastic body out of the deal, but he never anticipated how much maintenance a beautiful female body would be. After a few months, he realized that he just couldn’t stop his new body from gaining weight. He tried exercising; he tried a diet; none of it seemed to work. Just how did skinny girls stay thin? How did this girl do it before? The answers eluded him as he looked at himself in the mirror a year later. The same outfit he had wore the day of the Shift now felt so much tighter on his fatter frame. He was still attractive, but he longed to have the same skinny body that he had right after the Shift had swapped him!
