If busy, hunger is something I can choose to ignore very easy, to the point I essentially do not feel it.
I know it's there, if i think about it, but no, i wouldn't "feel" it.
Eating the same food for weeks on end? Why not, what difference does it make, so long as it's sufficiently healthy, and I at least like the food.
There are foods i don't mind, or can eat now and then, but not every day, but most foods, (what i'd call normal foods, though that doesn't mean much coming from me) i could eat every day for quite some time.
Also, the presence of food does remind me of hunger enough to make me start to feel it. I mean if there is a bowl of chips on the table or something like that.
