GrammiHow to count calories when eating out
Restaurant food is where most food diaries go quiet: no barcode, no label and no scale. You do not need exact numbers to keep counting. A reasonable estimate, logged, is far more useful than a blank day.
Step by step
- Split the plate into its main parts. Most meals are a protein, a starch, vegetables and a sauce or dressing. Log each part on its own instead of hunting for the exact dish: grilled chicken, fries, salad, sauce.
- Estimate each portion by size. A palm-sized piece of meat or fish is about 100–150 g. A fist of cooked rice or pasta is roughly 150–200 g. A thumb of butter or oil is around a tablespoon. Compare with what you know from weighing food at home.
- Assume a restaurant portion, not a home one. Restaurant servings are often larger than what you would serve yourself, and kitchens are generous with oil and butter. If in doubt, log the larger portion and add a tablespoon of oil for fried or sautéed dishes.
- Do not forget drinks, bread and dessert. A soft drink, a glass of wine, the bread basket and a shared dessert can add as much as the main course. Log them as separate entries.
- Use published nutrition when there is some. Many chains print calories on the menu or on their website. If the restaurant gives a number, use it.
- Log it and move on. Do not try to make up for it by skipping the next meal. One estimated dinner hardly changes your weekly average; the habit of logging is what matters.

Logging it in Grammi
Search for each part, pick a typical portion and adjust the grams if your plate looked bigger or smaller. Logging every meal is free in Grammi, with no ads and no account. With Grammi Pro (optional, iPhone 15 Pro or newer) you can photograph the plate: Grammi lists every food it sees and you check the list.
Questions
How do I estimate calories at a restaurant?
Split the meal into its parts (protein, starch, vegetables, sauce), estimate each portion by size, and assume the larger restaurant portion plus some added oil.
Is it worth logging a meal if I can only guess?
Yes. A reasonable estimate keeps your weekly picture honest; a skipped entry makes the day look lighter than it was.
Should I eat less later to make up for a big meal?
There is no need. Log it and carry on as normal; your weekly average matters more than a single dinner.
