People think I'm skinny and I'm 1.82m, fairly narrow build, and usually 78kg-82kg. I've never worried about what I eat. My weight has been more or less constant. I know other people have to be very careful or they easily put on more weight. There is very little fat on me (maybe I could go a little bit leaner but I mostly don't worry about it). That said, I think extended fasts are not about managing your weight, they're intended to force your body into a different mode. I'm pretty sure they're not an efficient way to reduce your weight (more activity + a bit more control over what you eat would be better). If you want to increase your weight without being fat then resistance training + eating more.
