Weekly shopping: list and budget

Stick to the perimeter. Meat, fish, vegetables, and dairy are almost always placed along the walls, while the central aisles contain grains, baked goods, snacks, and ready-made sauces — exactly what you do not need.\n\nThis is not a trick but a way to save time and decisions: the fewer times you pass the sweets aisle, the fewer reasons you have to make the decision again.\n\nThe second rule is not to go to the store hungry. A list in your hand works less effectively than being full.

Choose the type of fish carefully: mackerel and herring provide the same fat as salmon at a price several times lower. Choose the right form: frozen instead of chilled; the difference in the finished dish is small.\n\nWith meat, chicken thighs and drumsticks are cheaper and fattier than breast, which is a plus here, not a minus. Organ meats are inexpensive and nutritionally outperform many expensive options.\n\nWith greens, choose seasonal local produce instead of packaged salads. In winter, cabbage provides volume more cheaply than any packaged arugula.

On cooking oil: cheap refined oil is what you pour over your salad every day, and the difference is noticeable here.\n\nOn ready-made sauces: the money saved comes back as hidden sugar. A dressing made from oil, vinegar, and salt costs pennies and takes a minute to prepare.\n\nAnd on the amount of greens. Cutting salad to fit the budget means going without fiber, and that is the first thing to affect how you feel during the first month.

The list is designed for a healthy adult. With chronic kidney disease, the amount of protein and potassium-rich foods is determined by a doctor, and the quantities in the table do not apply in that case.\n\nDuring pregnancy and breastfeeding, do not switch to this list on your own. If the gallbladder has been removed, increase the amount of fat gradually rather than immediately following the weekly allowance.

Once a week for the main shop and once in the middle of the week for greens.\n\nProtein, oils, canned foods, seeds, and nuts can easily be bought a week ahead. Greens and salad do not last that long: by the fourth day they wilt, and half ends up in the trash.\n\nIf daily shopping is inconvenient, some vegetables can be bought frozen — broccoli, cauliflower, and green beans work no worse than fresh.

Use it, but fill your basket when you are not hungry.\n\nThe advantage of delivery is that you do not have to pass the sweets aisles. The downside is substitutions: instead of what you ordered, you may receive something similar, and “similar” often turns out to contain sugar.\n\nThat is why it is worth disabling automatic substitutions in the app wherever possible and checking the ingredients on the product page before ordering, not after delivery.

No exact figure can be given — it depends on the city, the season, and what you choose within each group.\n\nWhat can be said for certain is that the difference between the expensive and budget versions of this list is several-fold, and it comes almost entirely from fish and meat. Mackerel instead of salmon and chicken thighs instead of breast affect the total more than any other choices.\n\nAt the same time, an expense category that people usually overlook disappears: snacks, takeaway coffee, and evening delivery. For some people, this makes up the entire difference.
