The Building-Block System: 5 Basics, 20 Meals

Why meal prep turns boring by Wednesday and how five building blocks turn it into twenty meals — without more work on cooking day.

Introduction

The honest answer to why meal prep collapses on Wednesday: it is not discipline, it is monotony. And the fix is not more willpower, it is different arithmetic — do not cook five finished dishes, cook five building blocks.

Two protein sources times two sides gives four bases. Four bases times five sauces and toppings gives twenty meals that feel different. The work on cooking day stays the same. Only the order changes.

And it is worth it, because cooking at home is associated with better diet quality: households cooking dinner six to seven evenings a week averaged 9,054 instead of 9,627 kilojoules a day and 119 instead of 135 g of sugar [4] — observational data, not proof of causation. But that advantage only counts as long as you keep it up. Which is exactly what this is about.

What You Need

Step by Step

1. Do the combinatorics once

Two proteins (chicken, red lentils) times two sides (rice, potatoes) makes four base dishes. Add three sauces and two toppings and you are mathematically at twenty different plates.

The point is not the maths. The point is that on Wednesday you make a decision instead of a repetition.

2. Choose the blocks so the protein adds up

Every combination has to hit your protein target, otherwise the system is pretty and pointless. Plan each meal around 0.4 g of protein per kilogram of body weight across at least four meals [1] — which matches the usual recommendation of 20 to 40 g per portion, or 0.25 g per kilogram [2].

In practice at 80 kg: about 32 g per box, so roughly 150 g of chicken breast, a large ladle of lentils with cheese, or 200 g of low-fat quark as a dessert block.

Remember: the sauce may vary, the protein amount may not.

3. Store separately, combine on the plate

This is the difference between a building-block system and five identical boxes. Sauce soaks into the starch overnight, vegetables go soft in a sealed container, and by day three every box tastes the same.

But separate storage does not mean longer storage: all components stay within two to three days in the fridge [3]. The advantage is different — you control the order and use up the delicate blocks first.

4. The four flavour levers: acid, fat, crunch, heat

Why prepped food seems bland from day three is less a quality problem than a perception one: your palate adapts to a constant flavour profile, and reheated dishes lose volatile aromas on top of that.

The remedies are cheap and work instantly — kitchen experience, not study evidence:

A spoon of yoghurt and a squeeze of lemon turn leftovers into a dish. Ten seconds of effort.

5. Rotation instead of randomness

Set two weekly patterns, A and B, and swap exactly one block per week. Next week the chicken stays but the side moves from rice to potatoes. The week after, the side stays and the protein changes.

That keeps the shopping predictable and the kitchen routine intact — and it still never feels like the same food.

Common Mistakes

Safety Notes

This guide does not replace medical or dietary advice.

Separate storage extends no deadline: in a building-block system too, two to three days in the fridge applies, after which the rest belongs in the freezer — decided on cooking day [3]. Plan delicate blocks such as fish, dishes with raw egg and leaf salad for the first one to two days.

Stricter rules apply to pregnant women, small children, older people and anyone with a weakened immune system: shorter windows and, in doubt, fresh rather than prepped. And if a block smells or looks doubtful, the date on the lid decides, not your nose.

Pro Tip

Build three sauces that have nothing to do with each other — say a yoghurt-and-herb sauce, a peanut-soy-lime sauce and a tomato-harissa sauce. Ten minutes of work, a few cents per portion, and the same base of chicken and rice tastes like three different countries.

Second trick: introduce a swap block that is never planned. A pot of skyr, a tin of chickpeas, a piece of leftover feta — something you throw on top on the day you least expect it.

And if you would rather not work out the swaps yourself: the nutrition plan in the DOMISPORTS training centre has a meal-swap function that exchanges individual dishes while keeping the macros stable. That is not a workaround — it is exactly this principle, automated.

FAQ

Why does meal prep taste bland after three days?

Because your palate adapts to a constant flavour profile and reheated dishes lose volatile aromas. The food has not got worse, your perception has shifted. The remedies are acid, fresh fat, crunch and heat — added on the plate, not on cooking day.

How many components do I really need?

Five is enough: two protein sources, two sides and one tray of vegetables, with sauces and toppings as the variation layer. More blocks mean more shopping, more containers and more spoilage — and a lower chance that you do it again next week.

Store separately or assemble fully?

Separately wherever possible. Sauce and raw vegetables belong in their own containers, because otherwise they dictate the texture and flavour of the whole box. Shelf life does not change: it stays two to three days in the fridge [3]. Assembling fully is only worth it for the next day.

How do I keep protein constant when I swap components?

By treating the protein source as the fixed quantity and varying only the rest. Plan around 0.4 g per kilogram of body weight per meal [1], or 20 to 40 g per portion [2], and keep two or three anchors in your head — roughly 150 g of chicken breast or 200 g of low-fat quark.
