Should you skip breakfast after a big dinner? No need. One big meal doesn't need making up for, by skipping meals or by extra exercise; the next step is simply your next regular meal, or your treatment plan if you have one.

Every night, your body runs for hours on energy it stored earlier, and breakfast tops it back up. Nobody calls that breakfast making up for the night. Yet after a holiday dinner or a birthday, a little voice can say you now have to make up for it, like an accountant with a long receipt. Feeling like you blew it is not the same as having blown it.

## What does one big meal actually do?

Your body does not settle energy meal by meal. During and soon after a meal, it usually takes in energy faster than it uses it, and stores some. Between meals and through the night, it keeps using energy and draws on those stores ([Hall and colleagues, 2012](https://pmc.ncbi.nlm.nih.gov/articles/PMC3302369/)).

![A drawing of energy in, energy out: an accountant's demand to settle it by tomorrow is crossed out, because the line is always moving and has no deadline, and the idea that a birthday cake does not count is crossed out too: it counts](/images/blog/skip-breakfast-after-big-dinner-content-1.webp)

A big meal, with more energy in it, can make a bigger rise. That is real, and we are not going to pretend it is zero. But it is one rise on a line that keeps moving. The line in the video is an illustration, not a prediction of your body's response: it does not show the dinner being cancelled overnight, and it cannot tell you where your own stores will be tomorrow. For scale, three meals a day is 21 meals a week and 1,095 a year; one dinner is one of them.

The next morning, some of that meal may still be moving through your gut, and your body may be holding extra water with the carbohydrate it stored. Hall and colleagues name hydration and gut contents as the main contributors to ordinary day-to-day changes in body weight, and one small exercise-recovery study found muscles storing water along with glycogen ([Fernández-Elías and colleagues, 2015](https://link.springer.com/article/10.1007/s00421-015-3175-z)). Neither is a verdict on you. Our next video covers this.

## What is the what-the-hell effect?

If one meal is a small part of a long pattern, why can it feel so huge? Sometimes, breaking a food rule brings the thought: why bother now? Researchers call a related eating pattern the what-the-hell effect.

In a classic 1975 experiment, Peter Herman and Deborah Mack gave women zero, one or two milkshakes, then an ice cream "taste test" where they could eat as much as they liked. On average, women with high scores on a dietary restraint questionnaire, a measure of holding back on food, ate more ice cream after a milkshake than without one. Low scorers did the opposite ([Herman and Mack, 1975](https://pubmed.ncbi.nlm.nih.gov/1206453/)). One reading is that the milkshake broke their rule for the day, so the rule stopped holding them back.

That was a laboratory finding. In everyday life, Janet Tomiyama and colleagues did not detect more eating after female university students felt they had broken their diet ([Tomiyama and colleagues, 2009](https://pmc.ncbi.nlm.nih.gov/articles/PMC2761536/)). So this is a possible pattern, not a law.

Still, the thought is worth noticing. Sometimes, all-or-nothing thinking can make one meal feel like a ruined day, and a ruined day feel like a debt. That feeling does not mean you owe anything.

## Does being kind to yourself help?

In a 2007 study by Claire Adams and Mark Leary, 84 female undergraduate students took part, and some were asked to eat a doughnut. Some of the doughnut eaters then heard a short, kind message from the researcher, roughly: everyone eats like this sometimes, so don't be hard on yourself. Among women with high restrictive eating scores, those who heard it reported feeling less bad than those who only had the doughnut ([Adams and Leary, 2007](https://self-compassion.org/wp-content/uploads/publications/AdamsLearyeating_attitudes.pdf)).

It was one laboratory session, and women diagnosed with or treated for an eating disorder in the past three years were excluded, so it is a hint, not a cure. Results for later candy eating were less clear, which is fine: kindness is not a technique for eating less. The point is to stop treating a meal like a debt.

## What should you do after a big meal?

Nothing special. Have an ordinary meal at a regular time, not a smaller one to make up for it. After a big dinner, that means breakfast as usual the next morning. Keep eating regular meals and snacks, or follow your treatment plan if you have one. There is nothing to pay back.

Butterfly Foundation's holiday guidance recommends keeping to your usual meal routine or meal plan and not compensating afterward ([Butterfly Foundation, 2022](https://butterfly.org.au/tips-for-easter-while-living-with-an-eating-disorder/)), and the US National Eating Disorders Association lists meal skipping and compensatory exercise among disordered eating patterns ([NEDA](https://www.nationaleatingdisorders.org/what-is-the-difference-between-disordered-eating-and-eating-disorders/)).

You still deserve nourishment and care, whatever you ate yesterday.

## What this does not mean

- It does not mean one meal has no effect. It adds energy, like every meal.
- It does not mean every next-morning change is water.
- It does not mean self-compassion is a way to eat less.
- It does not mean a big meal is a binge, or that distressing loss-of-control eating should be brushed off.
- It is general information, not medical or nutrition advice. For advice about your own health, talk to your doctor or an accredited dietitian.

## Frequently Asked Questions

### I ate a lot last night. Should I skip breakfast?

No need to skip it to make up for dinner. Have an ordinary breakfast, or your next regular meal, at a regular time.

### What should I do after overeating?

Keep eating regular meals and snacks rather than cutting back to compensate, or follow your treatment plan if you have one. There is nothing to pay back.

### Does one big meal still count?

Yes. A big meal adds energy, usually more than an ordinary meal. It is one bigger rise on a line that keeps moving, not a bill due the next day.

### How do I stop feeling bad after eating a lot?

Try answering yourself the way you would answer a friend. In one small lab study, a short kind message helped the most restrictive eaters feel less bad. If eating brings distress, loss of control or pressure to compensate, you deserve support.

## If eating feels hard

If eating brings distress, a loss of control or pressure to make up for food, you deserve support. A professional experienced in eating disorders can help.

## Video transcript

The full narration of the video, with its chapter times. The video is coming soon.

**0:00 Does one big meal need making up for?**

Every night, your body runs for hours on stored energy, with nothing coming in. Then breakfast tops it back up. And nobody calls breakfast making up for the night. But after one big dinner, a little accountant shows up in your head with a very long receipt, and one demand: pay it back. So, does one big meal really need making up for? The accountant's maths sounds solid. Energy in, energy out, so extra in tonight has to be balanced by tomorrow. Right? Not quite. Your body doesn't settle up meal by meal, or day by day. It stores some energy after you eat and draws on it between meals and all night, so the line is always moving, with no midnight deadline. The opposite guess, that it doesn't count at all, is wrong too. A big meal does add energy, usually more than an ordinary meal. It counts. It just doesn't come with a bill, or a due date.

**0:54 What does one big meal actually do?**

So let's draw it. Stored energy rises after meals and falls between them. Here's that dinner, and up close, it looks like a mountain. Now zoom out. Breakfast the next morning, then lunch, then a whole week of ups and downs, every one a little different. The dinner's still there, taller than the rest. It's just one bump on a line that never stops moving.

**1:15 What should you do after a big meal?**

So, no. One big meal doesn't need making up for, not with a skipped meal and not with extra exercise. It adds energy like every meal does, but one meal doesn't describe how you eat, so the next step is simply your next regular meal. Count them: three meals a day is 21 a week, and nearly 1,100 a year. The accountant is judging a whole book by one page, with a magnifying glass. We make a food-logging app, kcalm, so you might expect us to side with the accountant. We don't. A food log is a diary, not a bill.

**1:52 Does being kind to yourself help?**

So what's the opposite of a bill? One study tried kindness. 84 college women took part. Some ate a doughnut, and some of those then heard a short, kind message from the researcher, basically: everyone eats like this sometimes, so don't be hard on yourself. Among the women who scored highest for restrictive eating, the ones who heard it felt less bad than those who just had the doughnut. One lab session, not a treatment test, so it's a hint, not a cure, and not a trick for eating less later. Still, a better deal than the receipt. If you have a treatment plan, it comes first. And if that voice is loud, or eating brings distress, a loss of control or pressure to make up for food, you deserve support. The numbers are on screen and in the description.

**2:36 Skip breakfast after a big dinner? No need**

So, the morning after the big dinner? Your body ran through the night on stored energy, the way it always does, and breakfast isn't making up for anything. It's just breakfast. The accountant can take the morning off. This is Food, Explained, from kcalm.app. Next time: why does your weight change overnight?
