Does splitting one portion into two meals work?

Splitting a portion that comes out large solves both that meal and the next one at once. But what really decides things is not whether the split is made but when it is made.

When is it split?

Splitting works if it is done before the meal starts. When the plate comes in front of you, the part set aside goes into a container and out of sight; the meal goes on over what is left.

Trying to split after the meal has started rarely works. Separating from a plate you have begun eating is neither practical nor free of a decision in the moment.

So splitting is not a matter of willpower but a matter of order. The same decision is easy at the start of the meal and hard in the middle of it.

How is it done at home?

At home the splitting is done while the food goes from the pot to the plate. What comes to the table is one meal's worth, and the share for the second meal is already in a separate container in the refrigerator.

This arrangement calls for a separate container but creates no extra work. The food was going into a container anyway; the only change is that this is done before serving rather than after the table is cleared.

Using a single-meal container is what makes the method last. Food put into a large container has to be split again the next day, and that step is most often skipped.

What do you do when eating out?

In a restaurant the portion cannot be changed, but part of it can be set aside when the plate arrives. Because that separation is physical, it keeps reminding you throughout the meal.

Asking for a container is a more definite method and is becoming more common. A decision like that made at the moment of ordering is far easier to follow than one made with the plate in front of you.

Sharing gives the same result. Splitting one main dish between two people adjusts both the portion and the number of orders at the same time.

Which dishes suit this?

Dishes whose texture does not suffer from reheating are the most suitable for this method. Stews, legumes and baked items stay the same the next day.

Fried food and dishes with a crisp coating are not suitable. In these, the part set aside does not taste the same the next day and usually stays unused.

With salads, the dressing has to be kept separate. A salad sitting with the dressing on it releases its water within a few hours; when the dressing is carried separately, the second meal is close to its first state.

Where does it turn into fooling yourself?

Taking the part you set aside back during the same meal makes the method completely useless. That is why moving the set-aside part out of sight matters as much as setting it aside.

The second mistake is assuming that splitting automatically reduces the amount. A split portion is spread over two meals; it does not disappear, and this calls for the right expectation about what the method is.

The third is forgetting the second meal. If the part set aside sits unused, the method turns into waste; so when it will be eaten should be clear from the start.

All three mistakes come from the same source: treating the split as an operation rather than a solution. Splitting works only if you know from the start where the part set aside is going.

What does this arrangement make easier?

The most concrete convenience is that the next meal is ready. The share set aside turns directly into the next day's lunch container or the answer to a busy evening.

The second is that the portion decision is made once, at the start of the meal. A question asked over and over during the meal comes down to a single decision and the rest needs no thinking about.

The third is less waste. A plate you clearly cannot finish is most often left half-eaten and thrown away; the second half of a portion split from the start is kept without spoiling and actually gets eaten.

Whether a portion should be split in two changes from person to person; that is something a dietitian tells you. This content is for general information; it does not replace medical diagnosis or treatment and does not constitute personal nutrition advice.
