Hm hard to say, I always eat until I feel satisfied im my stomach :-)
But what is even more important for me is to have real good quality dates that just taste amazing and are as fresh as possible. I always hated dates but when I tasted real fresh dates it was me and dates forever.
I usually Eat about 500calories of dates per day- in my morning smoothie and during the day I snack on seedless dates.
It was a long way for me to find the right dates in big quantities.
I buy them here: https://www.dattelbaer.at/ they ship in austria and germany so far. But they are also availabe in holland.
good luck hope it helped.
