I currently do a very similar regime (sunrise is at 4:30ish, sunset 7ish at the moment): wake 4:30 ish, skip breakfast, eat a light meal 300ish kcal at 11, and then have dinner of some meat and veggies at ~4pm. 8 -- 8:30 bedtime. It's really incredible since I have also shifted my work hours to 6 am -- 2-3 pm. It feels pretty good. I was doing a single-meal version of this regime for several months, but at one point my body started craving for a slight influx of calories at noon.
