If you are a beginner everything works. But if you want to look "like you go to a gym" and not like a powerlifter, you will need to switch to more hypertrophy based programs.
As someone who has been working out since I was 12, diet is AS important than lifting weights. No amount of lifting will get you anywhere without proper diet. If anything, it can lead to being injured or sick. Doesn't matter whether you want to look like a powerlifter or not.
