Enjoy Life and Food Without Losing Sight of Your Goal

01What this is about

Friends invite you to dinner. Your annual vacation is coming up. Christmas is around the corner. And your mind starts calculating right away: "How do I get through this without ruining everything?"

Some people order just the salad. Others cancel because they don't trust themselves to stick to their resolutions at the table. In coaching, I see again and again how people withdraw because of this: first from restaurant evenings, then from birthdays, eventually from almost anything that involves eating. The sentence behind it is usually: "I can't do this right now, I have to say no, or I'll fall off my plan."

That's understandable — and still a bad trade. We are social beings. Eating together is one of the oldest ways of creating closeness: the date with your partner, your best friend's birthday, the first evening of a vacation. You know the principle behind this from the article "The Dose Makes the Poison." Here we look at the side that got little room there: what restriction does to your life, not just to your plate.

02What the science says

When food excludes

The psychologist Kaitlin Woolley and her colleagues have shown in several studies that food restrictions are linked to more loneliness.¹ The reason: eating together connects people, and if you eat differently from everyone else, you feel left out more easily. On top of that come "food worries" — the fear of how others will judge your choices. When those affected could eat the same as everyone else, the effect weakened considerably.

A note on context: These studies look at food restrictions in general, such as medical or belief-based ones, not specifically at diets for weight loss. The mechanism carries over well, though — and it matches what I see in conversations with clients.

How big are a few holiday days, really?

The Christmas season is well studied. In a widely cited US study, participants gained only about half a kilo on average over the holidays.² A large study from Germany, Japan, and the US found a similar picture: small gains around the holidays, in the range of a few hundred grams to just under a kilo.³

Two things follow from this. First: the holidays are not the drama they are often made out to be. Second, and this is part of being honest about it: that small plus stays with some people if it doesn't settle back down afterwards. So what matters is less the festive evening itself and more how you find your way back into your everyday routine.

The math: what one generous evening really adds up to

One kilogram of body fat holds roughly 7,000 to 7,700 kcal. The commonly cited rule of thumb (about 7,700 kcal per kg, or 3,500 kcal per pound in the US version) goes back to a calculation by Wishnofsky from 1958.⁴ The figure is an approximation: fatty tissue isn't pure fat, and your body adjusts its energy use when your weight and eating habits change.⁵ As an order of magnitude for single days, though, it works well.

Let's be deliberately generous. Say your daily energy need is 2,400 kcal. A normal dinner for you is about 700 kcal. Your restaurant evening looks like this:

Course	approx. kcal
Aperitif	150
Bread with butter	200
Starter	350
Main course	900
Dessert	450
Two glasses of wine	300
Total	approx. 2,350

That's about 1,650 kcal more than a normal dinner. If you eat the rest of the day to your normal needs, that's a surplus of around 1,650 kcal. Divided by 7,000, that comes to about 0.24 kg, or roughly 240 g. At 7,700 kcal per kg it would be about 215 g. And that's a very lavish evening — the result is still just under a quarter of a kilo, at the very most.

Now the key comparison: this evening is one meal in a week of 21 main meals. The other six days, you eat completely normally, just like always. You don't make up for it, you don't cut back — you simply enjoy the evening and carry on as usual afterwards. That's the point: an exceptional evening needs no compensation, because by the numbers it barely registers.

The math would look very different if every evening looked like this. Seven evenings with a 1,650 kcal surplus each add up to roughly 11,550 kcal a week — about 1.5 to 1.65 kg of body fat, seven times as much. That is exactly the difference between the exception and the rule: it isn't the special evening that changes your results, but what you do day in, day out.

If the scale shows a kilo more the next morning, that isn't fat. Salty food, alcohol, and lots of carbohydrates bind water, and your gut is simply fuller. These fluctuations are normal and settle back within a few days.

A note on the math: The calorie values per course are rough estimates and vary widely from restaurant to restaurant. The figure of 7,000–7,700 kcal per kg of fat is an approximation, not an exact conversion factor.

03The big picture: the ultramarathon

Think of your eating like an ultramarathon. Nobody wins or loses one on a single kilometer. If you stop a bit longer at the aid station at kilometer 38 and enjoy something, you're not out of the race. What matters is your pace over the whole course — and that you stay in the race at all.

A week of vacation, the holidays, or a lovely evening at a restaurant with your partner are a tiny part of the course. The course itself is the many ordinary days: Tuesday lunch, Thursday evening, the third Monday of the month. That's where your result is decided, not at the Christmas dinner.

04How to put it into practice

A restaurant evening with friends or your partner

Choose what you really feel like, rather than tasting a bit of everything. Eat normally before and after, without fasting beforehand. And talk, laugh, stay at the table: the evening is about the people, not the plate.

Buffets and all-inclusive on vacation

Take a look at everything first, then take what you really want. A well-filled plate with protein, some vegetables, and whatever you feel like is usually plenty. Everyday movement (walking, swimming, exploring) helps, without turning your vacation into a training camp.

Christmas and family celebrations

Don't count course by course. Treat yourself to the things that belong to this celebration for you. If you like, plan a calm walk or a normal meal with vegetables and protein for the days in between — not as a punishment, but because it feels good.

An invitation at friends' places

You don't have to explain why you eat something or not. A "That looks great, I'd love some" is enough. And when you're full, you're allowed to say so, too.

The days after

The first day after your vacation is an ordinary day. No compensatory fasting, no extra workout. You pick up your everyday life again — and that's the part that counts the most.

What this can look like

Picture Anja. In everyday life, she eats the way that suits her: a protein-rich breakfast, something filling with vegetables at lunch, usually something simple in the evening. She has no list of forbidden foods, just a few habits that have proven themselves. That's her everyday life, and it carries her results.

Now she's invited to her best friend's birthday: restaurant, set menu, dessert. In the past, she would have turned it down, or gone and spent the meal mostly calculating.

This time she goes, orders the dish she's been looking forward to, shares a dessert with a friend, and talks a lot. The next morning she has her completely normal breakfast, with no compensating and no guilt. The result: a lovely evening, no bad mood, and the following week, the same everyday routine as always. By the numbers, that evening barely changed her results, and she had nothing to make up for.
