I live walking distance from 2 small super markets, I walk to those near every day and just get a few things and I also get hello fresh and I always cook those. So generally my fridge is pretty empty but I always eat well. Just in Time Home Economics you could say.

1. Consider therapy or medication.

2. Buy nonperishables in a higher ratio, such as canned, pickled, or dry goods.

3. If you’re not concerned about your health enough to cook your own food every day, then just don’t buy food that has to be cooked every day.

4. Remind yourself why you’re doing it, set a timer, and get it done. “This is for me. I love good food, I love my body.”

I just hunt and eat the homeless. I work for the municipality so I just leave what I don’t eat around park benches, bus stops and the front of stores to scare the rest away.

We cook and eat the food.

Buy stuff you don’t have to cook. It’s crap nutritionally, but at least it isn’t wasted!

Buy empty deli containers and food prep at least half the meals for the week.

Clean up fridge on day off, note overstock and old stock

Plan meals for the week using the over/old stock.

Use the pickup service at the market instead of shopping so you don’t buy stupid things.

When you buy raw meat, cook it within two days, even if you’re just going put it back into containers, it’ll last far longer.

This happens to us - if I cook dinner for everyone, two of us eat, if I cook dinner for two of us, everyone wants to eat. If I make enough for leftovers, nobody takes them to lunch. If I don’t make enough, they ask why there is not enough for lunch.

Things that help on your question though -

Canned beans, canned tomatoes, canned coconut milk, canned pumpkin, jarred spaghetti sauce, spices - a lot of our staples are not perishable.

Do you live where you can stop by the store on the way home? Then don’t buy perishables for the week, buy them for the meal you are making.

Some foods and meals freeze pretty well, freeze them and keep a list of what’s in the freezer so you remember to eat it.

I hate meal planning but it helps a lot. I sometimes put a note on the fridge “we have food for dal with spinach, chicken & cabbage, sheet pan gnocchi with sausage and broccoli, eggs and potatoes” or whatever we have the food to make, and cross them off as they are made.

Some foods make other foods. So if I make a hunk of pork, it’s pork, rice and beans then enchiladas then burritos, and so on.

Perishables take more planning. Get just enough and have a plan to use it. Use canned and frozen food to account for uncertainty. Be aware of expiration dates of your food and plan accordingly.

Freeze stuff

Walk yo and from the grocery store

Buy stuff that will last a while

Grow your own produce

Why are you buying perishable food items in bulk? Are you an inarticulate fopdoodle?

Buy food that has a long shelf life - lentil, rice, beans, canned vegetables, salsa jars. As a bonus it also doesn’t have to be refridgerated.

Freeze your fresh bread and only defrost the amount that you’re going to eat.

Use a software/app to meal plane. (Mealie/Tandoor) You pick the recipes you fancy for the days/week/whatever period. It generates a grocery list containing exactly what is needed for the meals you chose, nothing else.

I haven’t thrown away anything in a couple years now. Oh and freeze leftovers if needed.

Cook in bulk for the week. Grocery shopping on Saturday, cooking on Sunday. Then all you have to do is heat things up at meal time.

*I should clarify that you only need to refrigerate, not freeze, the type of stuff I’m talking about. Works better if you’re vegetarian

I found that visitng shop frequently and buying a little each time helps with this. Also, knowing what you have and planning what to cook with stock in mind. Also, one might find better to buy at small grocery stores (turkish in my area). These have ability to buy as an example 10 or less potatoes instead of fixed 2.5kg of potatoes. That way you’re not bound to swiftly eat potatoes before they rot.
