(Anecdata): The past few years I've oscillated between periods of consistent exercise and then periods of inactivity and I definitely notice a pattern wrt hunger.
recent periods:
1. a period of months of inactivity.
2. a period of multiple months of morning exercise (running soon after waking, before any food)
3. a period of multiple months of inactivity
4. a period of multiple months of running again
The pattern I experience is clear: during the periods of exercise, after morning running, I don't feel any need/urge to eat breakfast. Easily skippable.
During periods of inactivity, my body craves breakfast. Not skippable without significant willpower.
