Hm. Here's the thing - gaining is helped by unbalanced eating. It's all about habits. First, you have to have a schedule of eating - and then seriously disrupt it, and then eat more.
When you have a regular schedule, your body will get hungry at that time. When I work late, for example, I will get hungry around 7 or so because that's when I have dinner with the little man. You gain weight by disrupting that schedule, so perhaps not fasting per se but disrupting your schedule.
When I was fattening him up, I would take him on road trips and deliberately at times not pack enough food in the car. By the time I pulled over to a restaurant, he would overeat - a lot. So you have to play around with your eating habits.
