This could just be broscience (I have no formal education in these matters) but I've heard that the need to constantly have calories can be mitigated by eating a ketogenic diet, as it prepares your body to be able to run off of your fat reserves efficiently. If you are in ketosis due to diet all the time then it is easier to fast because your body is already in ketosis. Obviously if you are skinny as a rake you will want to make sure to make up for fasting periods by eating a lot of food during your feeding window, as I doubt you are trying to lose weight.
I will state from first hand, anecdotal experience that a ketogenic diet greatly reduced hangry feelings for me. I ate to satiation at meals, and I could go much longer without eating.
