How do I design a feed for always displays items that never liked before?

I would like to design a feed just like Youtube which displays items that each your never liked before.

As far as I understand, a user can follow any other user's feed, however, that will result in showing items that follower always liked.

I can filter out after I receive data from API but then I will be very inefficiency since no one knows how many more times I have to request next feed until a certain amount of the number for the list made up, normally 25 items.

And filtering feeds is not allowed from API yet.
