Why do I eat more when I'm tired? Rest as part of looking after yourself

In my work, eating more when you're tired comes up most weeks, and it is an ordinary pattern. Research links short sleep with eating more. Mela Theory, the framework behind Nutrimelab, reads tiredness as a cue from the biology layer, and rest as part of looking after your body.

Say the alarm went at half past five. You were on the train by quarter to seven, the day was long, and dinner was fine. Now it's nine o'clock, you are on the sofa, and the biscuit tin on the kitchen side, which you have walked past all week without a thought, has started to call. You go and get one, then another, and you are halfway down the row before you notice you are not really hungry. You are tired, the kind of tired that wants something, anything, to make the evening feel a bit easier.

The question that tends to follow is a harsh one. Why can't I control myself when I'm tired? I'd ask a different one. What is the tiredness asking for, and is food the only answer on offer?

Why do I eat more when I'm tired?

Research links short sleep with eating more. A 2017 meta-analysis of studies that shortened people's sleep found they ate more during short-sleep periods than in normal-sleep ones. Mela reads tiredness as one of the loudest cues in the biology layer, and food as often the quickest answer to it.

Haya Al Khatib and colleagues reviewed 17 studies, with 496 people in total, in which researchers deliberately cut sleep short and compared it with a normal night (Al Khatib et al., 2017). Pooling the 11 studies with usable data, 172 people in all, they found that people ate more during short-sleep periods. These were controlled studies of partial sleep loss, so they tell you what tends to happen under study conditions rather than in your kitchen.

One of the earlier studies is smaller and gives a more everyday picture. Arlet Nedeltcheva and colleagues had 11 healthy adults, five women and six men with an average age of 39, spend two 14-day stays in a sleep laboratory, once with 5.5 hours in bed each night and once with 8.5 hours, with tasty food freely available (Nedeltcheva et al., 2009). Meals stayed much the same. What went up with short sleep was snacking, particularly between seven in the evening and seven in the morning. Eleven people in a lab with food on tap is a narrow window on real life, so I hold it loosely.

In my work I see the same shape in ordinary evenings. The meals hold, and it is the hour after dinner that gets louder. Tiredness can go the other way too, and for some people food stops appealing when they are worn out. Either way, Mela reads the appetite as information about the day. If you want the bigger picture this article sits in, I've written about looking after the body you have today, and rest is part of it.

Am I tired or hungry?

At nine in the evening it can be either, and often it is both. Mela reads hunger as tending to build slowly and accept most foods, while tiredness tends to want something quick, soft or sweet and to arrive with a heavy, flat feeling. Mela reads tiredness as the likelier answer if you ate not long ago.

A few things can help you tell them apart without turning it into a test. In Mela's reading, hunger often comes with a sense of emptiness and settles after a meal. Tiredness more often comes with heavy eyes and a pull towards the sofa, and the food you want is the one that needs no effort. Neither answer is wrong, and knowing which it is tells you what else might help alongside the food.

There is a third option that sits close to both, and it has its own article. Hungry, tired or bored walks through the difference when the evening feels empty rather than tired.

Eating when tired in the evening

Evenings tend to be loud for more than one reason, and tiredness is only one of them. Two others often travel with it, and each has its own piece.

The first is a long gap. If lunch was small or early and dinner was late, the hunger in the evening may be plain hunger, and there is more on a long gap since you last ate. The second is stress. A hard day can often make food the quickest comfort in the house, and that has its own explanation in why food can feel like the quickest comfort under stress.

On a tired evening all three can be in the room at once. Mela reads this as a reason to be curious about the evening. If you can name which one is loudest tonight, you have a better idea of what might help, and food can still be one of the answers.

Why do I feel guilty when I rest?

Guilt about resting often comes up. Mela reads it as a long-held sense that rest has to be earned, by finishing everything first. Mela places that sense in the identity layer, how you see and treat your body. In that reading, a body that is only allowed to stop once the work is done rarely gets to stop at all.

In Mela's reading, many of us pick this up early, from school reports that praised effort and later from workplaces that reward the person who stays late. Learned over years, it helps explain why the guilt can arrive even when you know, in your head, that you are allowed to sit down.

In my work I see that the people who eat most when tired are often the ones who won't let themselves rest. Food often works as a form of rest that doesn't look like stopping. You can eat standing up in the kitchen and still feel productive. A biscuit can be the only break the evening offers, and it carries the job that twenty minutes on the sofa would have done. You often stay tired, since the rest never happened, and you may feel worse about the eating that stood in for it.

Rest as part of looking after yourself

Rest is part of looking after your body in the same way that eating when you're hungry is. Mela places both in the same layer, as ordinary care rather than something to be earned. You would not ask a friend staying with you to justify going to bed. The same allowance can apply to you.

On an ordinary Tuesday, rest might look like ten minutes on the sofa when you get in, before the evening starts. It might be saying no to one thing this week, or leaving the dishes until the morning. It can be as small as sitting down to drink a cup of tea instead of carrying it around while you tidy. None of these needs a reason. They count as looking after your body even on days when you have done very little.

Say it's Thursday and you get in at seven. Ten minutes on the sofa with your coat off and the phone in the other room comes before anything else. Dinner might be a little later or a little simpler, and the biscuit tin might still be part of the evening. What changes is that the rest has already happened, so the food doesn't have to do that job as well, and you can eat the biscuit because you want it.

One thing to try this week

This week, when you notice yourself heading for food on a tired evening, pause long enough to say one sentence to yourself, "I'm tired." Then go ahead and eat if you want to. Nothing in this practice asks you to weigh, count, restrict or compensate. The only thing you are adding is the noticing, before you decide what your appetite means.

Then name one rest you would allow yourself that evening, whether or not you take it. Ten minutes sitting down, say, or one job left until tomorrow. Write it down if that helps. Over the week you will start to see which rests you allow easily and which ones still come with guilt attached.

Your one action for today is to pick the rest you would allow tonight and say it out loud.
