That's a pretty good schedule as is! Roman soldiers actually did something similar where, during the daytime, day only lightly snack on nuts and berries and have a full meal in the night.

Though my core lunch always consists of beans and peanuts which don't cause such "food coma" like consuming carbs does, so it works fine for me.

Though beans are still carbs in nature, it's important to distinguish that beans are low glycemix index, by which means they are digested much slower than say, wheat or barley, and of course much much slower than sugars. So that's pretty good!

But whenever I'm not working I start eating after 4 PM.

That's about right! I intend to revert to a 1 meal a day at around 6-7pm (or whenever work is done) to then have my meal. This fast has really shown me that hunger in of itself is something that is absolutely over-glorified.

If I were to have to for some reason, stop eating for 24 hours abruptly, that would call for a shrug of the shoulder and an oh well.

I like being in that position. It's a postion of immutable strength that no one can take away.
