You need to fast for the 12-16 hours before 6:00 am. So stop eating between 2:00...

But wont that put me to sleep right away - I usually feel sleepy after a meal. This seems counter-intuitive.

> I usually feel sleepy after a meal.

Carbs do that (e.g. potatoes). Try eating proteins and greens only instead and see if it still makes you sleepy.

the other theory i heard was that the stomach uses blood to churn food, which deprives the brain of blood

That means you're eating the wrong things.

I figured it out. What the article refers to is a strategy to not sleep during the long flight but instead starve yourself so you stay awake. And then when you eat, you basically reset your body clock to the start of a new day.

I think this is very early research and not really applicable.

...but instead starve yourself so you stay awake.

Staying awake during the fast isn't necessary.
