Meal Planning Mistakes: 7 Reasons Your Plan Fails (and How to Fix Them)

A meal plan usually fails for seven avoidable reasons: it is too rigid, leaves no free evening, ignores the new weekly promotions, overlooks what is already at home, plans dishes nobody likes, buys for an imaginary week and lives on a list only one person knows. Each has a simple fix. The full method is in the guide to meal planning in Switzerland.

Why does a meal plan fail?

Almost always because it is written for an ideal week that does not exist. A meeting runs late or a dinner invitation arrives, and the groceries you bought stay in the fridge.

The cost of that waste is measured. According to foodwaste.ch (viewed on 5 October 2026, sources ZHAW/BAFU 2025 and BFS 2023), each person in a household throws away about 80 kg of food a year, worth about CHF 600 per person. Households cause 26 % of food losses. This is not a savings promise: it is why it pays to understand where a plan breaks.

What are the 7 most common mistakes, and how do you fix them?

1. The plan is too rigid

Mistake: seven fixed dinners, one per night, no slack. Once one evening is skipped, everything slides.

Fix: plan dishes, not days. Pick five dinners, match them to days only loosely and swap evenings when needed. When ideas run out, start from what is in the fridge.

2. No leftovers night

Mistake: a new recipe every night, so Monday's risotto is left over and nobody eats it.

Fix: reserve one evening a week for “leftovers and improvising” and a second as a buffer. A deliberately larger portion becomes the next day's packed lunch.

3. You shop before the new promotions start

Mistake: you shop on Wednesday, a day before promotions change. According to a Migros press release, the weekly promotions of Migros and Denner start on Thursday, as they have since 5 February 2026, and run until the following Wednesday. Coop moved to Thursday in the week of 21 January 2025.

Fix: plan on Wednesday evening and shop from Thursday. Look at the promotions before you write the list: a dish built around a promoted product is an option, not an obligation.

4. You ignore what is already at home

Mistake: you write the list from recipes instead of from the fridge. Result: a third pack of rice and expired cream.

Fix: open the fridge, freezer and pantry first and note what must go first. Those ingredients become the first dinners of the week.

5. You plan dishes nobody at home likes

Mistake: the plan is a collection of good intentions while half the table frowns. The unloved dish ends up as a pizza ordered at the last minute.

Fix: write down the ten dishes your household always finishes and build the week on them. Add one new dish at a time.

6. You buy for an imaginary week

Mistake: you do not count the evenings you eat out, go to sport or finish late. You buy for seven dinners and cook four. Pack sizes matter too: a large pack for one person ends up in the bin.

Fix: check the calendar before choosing dishes and cross out the evenings without cooking. Plan only what you will really cook and compare the pack size with the portions you need.

7. No shared list in the household

Mistake: one person writes the list, another shops “just in case”: doubles here, forgotten milk there.

Fix: one list for the whole household, visible to whoever shops, where everyone adds what runs out.

How do I spot my mistake? Summary table

How do I restart in 5 minutes if the plan has already collapsed?

1. Write down three things that must be used first.
2. Cross out the evenings in your calendar when you will not cook.
3. Pick three or four dishes, not seven, and keep one evening for leftovers.
4. Write a single list with only what is missing and send it to whoever shops.
5. Postpone the rest: half a plan beats a perfect one that never starts.

How does Rappn help avoid these mistakes?

In the Kitchen of the Rappn app (iOS and Android) you pick a recipe and answer “When are you cooking it?”: you choose the day and the meal, for example “Dinner”, then tap “Add to plan”. In “Plan week” you see the days with their meals and how many are covered, for example “3/7 days covered”, so free evenings stay visible. From the plan you send the ingredients to a cart such as “Weekly shop”: the app separates what you already have at home from what you might already have, like salt or flour. Carts can be shared with the people you live with. Rappn is an independent, free price-comparison app with no commercial agreements with any retailer; recipes come from external publishers.
