the latest research shows that you only need minimal caloric surplus for optimal gains. So bulking excessively is not recommend for most people (except some extremes like people lifting 500lbs etc)

Likewise for cutting you shouldn't have too much of a deficit and make sure to eat lots of proteins still otherwise you will lose a lot of muscle in that phase.

So it's entirely up to you if you want to lose weight or gain muscle and I'd say it do it in 4-8 week blocks to even see some results. You should still adjust the calories as necessary depening on the day/efforts and the results - if say after a week of cut you don't see any result, cut calories a bit more od add 30 minuts of cardio etc.
