Oh yea, totally doable. I would be able to do this easily. Probably could get even better results and nutritional value than we enjoy now if I planned many smaller portions throughout the day. Though I am assuming most adults working a 9-5 probably only have time for 2 meals a day, maybe a snack.
No one in my family is big on snacks though- because we eat very well-balanced meals like almost every day. It is not a habit I ever got into throughout my life and my kids have only known eating the meals I prepare for them. I don't think that will be a big factor with thoughtful meal planning.
I have no assistance either. I do all the shopping, cooking, cleaning, and planning. I work a 9-5 too. It's a one-woman show over here, homie.
In fact, according to Nerdwallet's tracker in the last 30 days, I only spent about
$107 on Groceries. That only tracks the one credit card I have linked for budget planning. More accurately, let us say I spent twice that in 30 days on Groceries; $207. I likely bought some misc. stuff like steaks for backyard grilling & such with my husband's debit honestly. Bump it up to $300 in 30 days.
I could easily knock $50-100 off and we would still eat fairly well. But I am privileged as fuck. Stupidly so.
I agree on having kitchen space and so on. I would generally include that as part of having access. If the grocer was across the street but you have no place to store the groceries, it hardly matters wringing hands about what
access to grocery products means in a practical sense.
I don't believe in meal prep over much either. I think it is more of a hindrance. Space being at a premium for some can be solved in other ways.
I am not sure where you are getting I said pricing doesn't vary when I specifically mentioned it does in previous posts.
However, one can eat cheaply & healthily relative to income devoted for food with planning. A lot of people in desperate situations and circumstances of extreme poverty have no income for food. That is way different than economical meal planning.
I am a tracker and planner. Annoyingly so sometimes. I have budget sheets going back like 9 years at least in the basement on a hard drive. I am aware of my spending. Very.
The worst! I got involved with a project to set up meals and groceries at outdoor refrigerators around town. The fridges are stashed around the city. People can just get food.
