About skipping breakfast. The concept is Intermittent Fasting. Ideally if we consume less refined carbohydrates which are quick to deplete, getting energy from "slower" sources, the natural tendency would be to reduce the need for more frequent meals.

It doesn't have to be breakfast. If I'm going to skip anything, I'd rather it be dinner. That way half the time with less readily available energy, I'll be asleep, rather than thwart my cognitive abilities when they matter most, usually in the morning.
