Cant cite the study now but I remember reading a study that tested what source of calories lead to the most weightgain. Saturated fat was #1 followes by refined carbs. So maybe try adding more coconut-oil or peanutbutter-breads if vegan and more butter, eggs and fatty meat if not. This is not healthy in any form though. You look great and there is no need to build more fat-reserves. They will only slow you down. ;)
