Is it still a partial Miztvot keeping kosher part of the week ?

I’m keeping kosher part/most of the week mainly by being a vegetarian for home cooking and work sandwiches.

I do know that being a vegge isnt necessarily kosher btw

But at the weekends with my kids we often eat out or have takeaway, burgers pizza etc & quite frankly i prefer meat on these occasions

So i’m wondering does the part of the week where i’m keeping kosher still count or is it completely negated ?
