What changes when you order food from a screen?

Ordering food from a screen moves differently from choosing the same dish at a table. Here the decision is built not with a menu but with photographs, offers and suggested extras.

How does the screen change the decision?

The first information that reaches you on an order screen is not text but an image. The image shows not the real size of the portion but its best version. This is why the expectation and the plate that arrives often part ways.

The second difference is the ordering of items. The products that appear first on a screen decide far more than the ones written first on a menu, and that order is set by the system rather than by preference. The further down you scroll, the faster the chance of a choice drops.

The third is time. At a table an order is placed quickly; on a screen the browsing can stretch out, and every minute spent hungry makes the choice bigger. The decision is made at the moment hunger is highest.

Portion information is usually not visible on a screen either. At a table you can ask about the number of people or the size of the dish; on a screen there is no such counterpart. So how much is in the package that arrives is only understood once it is opened.

What do suggested extras do?

The drinks, desserts and side items suggested before the order is completed land at the weakest moment of the decision. The main dish has already been chosen and attention has dropped. A small addition is accepted easily at that moment.

The sum of those additions usually goes unnoticed, because none of them looks large on its own. The same effect is seen with a basket sitting beside you at a table. How visibility changes the amount is taken up in the article putting nuts into a bowl.

Offers reverse the direction of the addition: a larger option is presented for a small difference. Here the decision is made by the difference in price rather than by need. The same calculation seen with large packaging is set out in detail in the article buying the large package.

How do you order with a plan?

The simplest arrangement is to decide what you will eat before opening the app. When the decision has been made in advance, the screen becomes a place to search rather than a place to choose. The browsing time gets shorter by itself.

The second step is to order before you get hungry. The delivery time already stretches the wait out, and hunger rises through it. An order placed early is both more measured and better judged.

The third is not to stop while passing the extras screen. The function of that screen is not to remind you but to add. A decision made in advance makes that step ineffective.

Settling on a few fixed choices at the places you order from often shortens the browsing too. A dish you know is not weighed up again each time, and the portion that arrives matches the expectation. New places are tried one at a time.

What do you do with the plate that arrives?

The portions ordered are usually larger than one meal. Putting the food onto a plate rather than eating straight from the package makes the amount visible from the start. That single step keeps the decision from being left to the course of the meal.

Setting half of it aside at the start is a workable arrangement too. The part set aside is left for the next day and becomes a second meal. Why that decision is made in advance is described in the article splitting one portion into two meals.

The sauces that come with it are handled separately. A sauce poured straight on makes the amount unclear; kept to the side, the person makes the decision. The detail of that distinction is in the article measuring sauces.

What should you expect?

Ordering food is not a problematic choice to begin with, and presenting it as one would be misleading. On a tired evening, on a day spent travelling or at a crowded table it is a well-judged choice. The only thing that changes is where the decision is made.

Nor do these arrangements aim to reduce ordering. What they do is make sure the choice is made by the person rather than by the screen. The decision made afterward is entirely the person's own.

How often to order, for you, is something to talk about with a dietitian. The arrangements here look not at how often but at whose the decision made at that moment is.
