Think that is farmer vs hunter adaption. Hunters eat big meals less often, plant eaters eat small meals often as its more work to digest plants.

So humans doing both have genes for both, but maybe some humans have more of some of those.

The lack of logic in this thread is remarkable.

If 50% of the world is just fine without eating breakfast, that still means 4 Bn people are not.

Posting personal anecdotes as if that proves feeling low on energy without breakfast means something is wrong is a degree of irrationality I can’t believe is showing up on HN.

It’s fine to share personal anecdotes and experiences but so many here are sharing them as if it disproves all other things experiences and responses.

It's even more complicated, because it also depends on what yout eat for breakfast. Some food will sustain you for a longer time, some will give you an immediate sugary boost and then the inevitable fall (which could definitely be a big part of the "I feel lower energy when I eat breakfast" experience.

Seconding this. Additionally, I'm likely to fumble speaking tactfully as a result.

Thanks. I've never heard it framed this way. I've mentioned my appetite diminishes after aerobic exercise, but a common response is that I'm weird.

Interestingly my appetite sometimes skyrockets after certain activities like bouldering or weight lifting, so the diminished hunger response must be a bit more complex of a phenomenon.

Sorry, I was not clear. A plate of some meat + some vegetables, or variations of that. The kind of things you expect to eat for lunch in France (and, broadly speaking, in Europe).

What I meant by that is that this is a full starter for the day, not a "late French breakfast"
