I stopped feeling hungry in the morning a long time ago. Just unhealthy amounts of coffee, without sugar or milk. If I eat even just the tiniest snack or sweet, the food processing tract will "wake up" and it's over. But if I can avoid that, I only break the fast because of convention, not because of hunger.

But it's also very contexy sensitive: currently working from a place where I usually go for high calorie throughput sports (think Tour de France climbs, but higher and a heavier rider, obviously a lot slower but the energy demand is mostly mass x elevation, almost unpacked to speed) and my body is in "eat! you will need it!" mode every day. Crazy weight gain on the working days.
