I find breakfast the easiest meal to skip, and putting sleep in there and skipping late nate snacks makes a 16 hr fast fairly easy.

My wife is like you though, so obviously it depends on the person.

I had the same problem, but it gets easier if you train it.

I recently started cycling for 1h in the morning without having breakfast, and after a few days it became quite easy. Just don't try to convince yourself that it is somehow a bad thing to skip breakfast. Breakfast only makes you hungry for the rest of the day.

I'm doing 16h/8h intermittent fasting, and I only feel slightly hungry on some days in the last 1h before my feeding window.

I skip breakfast aside from one cup of unsweetened coffee and on the other end I brush my teeth for the night with my daughter when she goes to bed at 8pm.

At some point your body starts making modest amounts of ketones overnight/until you eat, so you can still be productive without eating.

If you're gonna work out early in the AM it does make sense to have some kind of fruit or light snack right before. Or you can drink BCAAs during the workout to keep you energized. Just don't let that turn into eating a proper breakfast at like 6am otherwise you're going to end up eating an extra 500+ calories a day.
