Eating out without losing the week
A side page of "Start here". The question is practical: "How do I eat at a restaurant or at someone's table without failing — and without becoming the person who cannot come?"
Why eating out is hard
Four things stack up when someone else cooks:
- Portions are larger. A Cochrane review of fifty-eight studies found that bigger portions, packages and plates lead people to eat more — a small-to-moderate effect per meal that, if it applied to the whole diet, would add roughly a tenth or more to daily intake. Restaurants serve to satisfy, not to fit a target.
- Fat is invisible. Oil, butter and cream are how food is made to taste good at scale; none of it shows.
- Alcohol. It carries energy, brings no fullness, and rarely gets written down. There is a page on it under "Something isn't working".
- No label. You cannot check, so you guess — and step 5 of this path covers how guesses go.
What actually helps
These are editorial suggestions, not trial results; the source above supports the portion point and nothing else on this page, so the grade is for that alone.
- Decide before the menu. Choose the kind of dish you will order before you sit down; the menu is designed to change your mind.
- Protein and vegetables as the anchor. Grilled meat or fish plus a salad or vegetables is available almost everywhere, fills you, and is easy to estimate. What you add to it is the choice.
- Half the portion is still a portion. Share, box half, or order a starter as the main. The review above says it plainly: the amount served drives the amount eaten.
- One "yes" and one "no" per evening. Bread or dessert or the second glass — not none of them (that is how people stop going out) and not all of them.
- Do not announce a diet. Nobody at the table needs to know, and announcing it invites the negotiation you are trying to avoid.
The family table
A family that will not change with you is the most common reason a pattern fails, and no page can fix it. What works is changing the amount rather than the food: the same dish, a smaller plate, more of the vegetable and less of the starch, no second helping. The person cooking does not have to do anything differently, which is the point.
One meal is not the week
A single restaurant meal above target changes a week's average by a little; a week of "I already ruined it" changes it by a lot. Step 1 explained why: the deficit is an average over weeks, not a daily pass/fail. Log the meal roughly, eat the next one as planned, and the week is fine. The page "After a bad day" under "Something isn't working" goes into this properly.
In the app, "ate out" is one free-text entry — no grams required.
