This question already has an answer here:
Meal prep is usually meant to be a week's worth of meals but how does that work with the three or four days in the fridge most leftovers are considered safe for? Is three or four days too conservative then or are meal preppers risking their health with meals five days or so old?
Added: My question is, in spite of recommendations not to exceed 3-4 or 3-5 days in fridge, how are meal preppers doing fine with eating foods a week old? (I assume they are anyway). For example I have six day old chicken and veg I have just frozen and debating over that would be fine for a meal prepper I think but not fine if following the recommendations.
