What is the purpose of a meal prep?

A little late but I just recently started making some meal prep for weight loss. I have a similar question to you. I have a few questions for what the purpose of meal prepping is. Should it be just prep for the entire week, prep for just a few days, prep for one day ect.? I personaly don't like the idea of meal prepping lunch and dinner for the entire week because It feels like I'm just binging on rice. I like making things in bulk but frequently switch up what I make each week so I don't get bored. I make around 3-4 portions for each meal and then eat each meal for 1-2 days. I also like the idea of prep as you go for the week. What is the purpose of meal prepping for you?
