Why does an eating routine slip when the season changes?

What slips when the season changes is usually not your resolve but the conditions that carry the routine: the hours of daylight, the temperature, what comes to the table and the social calendar all change at once. That is why the same routine is not expected to carry on in the same form anyway. What can be done is not to ignore the season but to build the same sequence again for the new conditions.

What changes in winter and in summer?

When the day gets shorter, the time spent at home in the evening gets longer. A longer evening widens the distance between the last meal and sleep, and that gap fills with something by itself; the issue is usually not dinner but this gap that opens after it.

In summer the opposite happens. Time spent outside increases, meal times shift and meals are skipped easily. In the heat a heavy plate feels unappealing, and the place of the skipped meal is usually taken by irregular snacking.

These two patterns differ from person to person and neither is a failing. They are an ordinary response to changed conditions; that the routine was not built for them is a separate matter.

The ingredients change too

A routine often rests on a few particular items: the same fruit every morning, the same vegetable every evening. When that item goes out of season, the routine finds nothing to rest on.

When the shelves at the market change, the shopping list changes with them. Summer recipes shift toward cold plates prepared quickly, winter recipes toward dishes that take a long time in a pot; even the preparation time differs with the season.

This is why the slipping often starts at the market. When it is not settled what will take the place of the item that carried the routine, everything else becomes unsettled too.

The social calendar works in the same direction. In summer invitations and meals eaten out increase, in winter the table at home runs longer; both are factors outside the routine that nonetheless decide it.

This is not a failure

With the conditions changed, the same routine carrying on in the same form was never likely. Reading the slip as a personal failing does not bring the routine back; it usually makes people drop it altogether.

The measure to look at is not that the routine never breaks but that you can come back after it breaks. The changes of season are the times that return is needed most often, and they repeat every year.

How do you rebuild the routine for the season?

The most durable thing is not the hours but the sequence. Links such as "the first meal after getting up" or "the main meal after work" work independently of the season; even if the hours shift, as long as the sequence holds the routine stays recognizable.

The second step is to replace the item that has gone out of season with an equivalent. Carrying on with the fruit or the vegetable in that season's counterpart, without breaking the same meal, is far easier than building a new routine; frozen vegetables can fill that gap too.

The third is not to start anything new during the transition week. A change of season is already a period of adjustment; adding a new routine to the same week makes both of them harder.

Nor do you have to rewrite the routine at the start of a season. Changing the item that changed and leaving the rest as it is usually takes less work than building a new plan, and lasts longer.

What can you do today?

You can write down the one or two items that carry your routine and look at which of them has gone out of season; usually what slips is not the whole thing but that single item.

If the hours have shifted, you can try letting the hours go and keeping the order of meals fixed. That is a one-step adjustment that can hold through the season.

In the period when the evening gets longer, moving the last meal a little earlier can help too. It does not give the same result for everyone; but it is the smallest move that narrows the gap a long evening opens.
