How do you get organised? Do you regular food and meal prep routines?

I’ve always struggled with organisation, when I’m prepped I enjoy the food and lose weight when I don’t have a routine it all falls into chaos. I’m curious those who work full time when do you do your food shop? Do you meal prep if so when and how many days? I don’t want my whole weekend to revolve around cleaning, meal prepping and shopping 🙈
