Winnie,
I was always bought up to clear my plate and not 'waste' food. & i also felt terrible leaving things.
I'd say, "just give me one scoop" "don't do me too much" & feel awful if i could just manage a few mouthfuls. But everyone else was fine with it!
I'm back to regular portions now.

The taste thing is crazy! One time everything would be salty, another i needed more salt. Somethings were too sweet, some bland. Ugh!
