Which restaurants print calories, and why?
The large chains, because the law makes them. In the United States, the FDA's menu labelling rule applies to restaurants that are part of a chain with 20 or more locations, which must disclose the calories of standard items on menus and menu boards, with a compliance date of 7 May 2018. In England, regulations in force since 6 April 2022 require businesses with 250 or more employees to display the energy of items in kilocalories, per portion, with the line "adults need around 2000 kcal a day".
That is why the board at a burger chain says 550 and the menu at the independent place round the corner says nothing. The figure is not a courtesy and not a measurement: it is a declaration the chain is required to make for a standard item, as a nutrition label is the producer's declaration for the product.
Rules differ elsewhere, and this page records only the two it has read. Where a figure is printed, the hard part of counting is done for you; where nothing is, the meal is a restaurant plate like any other, and the three questions do the work.
What is a printed menu figure worth, and what does it leave out?
Menu calories are worth a label: the chain's own figure for the item as it is meant to be served, a starting point you can quote rather than a guess from the plate. What it leaves out is everything that was not standard: the extra sauce, the larger portion the counter gave you, the half of the fries you did not eat, and the drink and sides that are usually printed separately or not at all.
It also leaves out the macros. A menu board prints calories, in kilocalories, and rarely protein, carbohydrate or fat. So a burger recorded from the board has a declared calorie figure and estimated macros, and since an item carries one source, it is recorded as an estimate that quotes the board: the printed calories are kept as read, the item as a whole says the macros were reasoned. That is more honest than calling it a label, and more useful than calling it a guess.
The portion is the other gap. "Adults need around 2000 kcal a day", printed beside the figure in England, is a reference, not your target; the figure beside it is for one standard item, and if you ate two, or the large size, or left half, the record needs your words: "the large fries, and I left a third".
What do you say to record a fast food meal?
The items, the figures you read, and what was not standard. "A cheeseburger, the board says 300, medium fries at 320, a cola at 210, and I added a sauce" is complete: the assistant keeps the three printed figures as read and estimates the macros; the portion needs no question, the words carry it, and the sauce, unnamed, costs at most one question, which one, or an assumption said in the receipt so you can correct it in a word.
| What you say | What is kept as read | What is estimated | How it is recorded |
|---|---|---|---|
| "A cheeseburger, the board says 300" | 300 kcal | Protein, carbohydrate and fat | One item, an estimate that quotes the board |
| "Medium fries at 320, I left a third" | 320 kcal for the standard portion | Two thirds of it, and the macros | One item at about two thirds of 320, an estimate that quotes the board; your words kept on the row |
| "A cola, the board says 210" | 210 kcal | The macros, nearly all sugar | One item, an estimate that quotes the board |
| "I added a sauce" | Nothing printed | The sauce, from the dish and the cuisine | Its own item, estimated |
| "A large latte and a muffin, no figures on the board" | Nothing | Everything, after a question on the size and the milk | Two items, estimated, after the question |
Bottom line: read the figure, say it, and say what was not standard; the printed part is kept, the rest is estimated and says so.
A photo of the board is read by the assistant as it reads a label: it echoes the figures it read, so a misread is caught in the same breath, then keeps them; what the board does not print is estimated. A photo of the tray does not work that way: it names the food and cannot show the size or the sauce, so the assistant asks before any number, as for any plate.
Do you need the chain's calorie calculator?
Not if you can read the board, and it helps when you cannot. Many people go straight to a chain's own calorie calculator, and the calculators are the chains' own declarations, item by item, sometimes with the macros the board leaves out. Use one if you like; what you then say to your assistant is the figure you read there, and it is kept as read.
IZeat has no chain database and no calculator of its own, today. That is a limit and a choice: a database entry for a burger is one chain's recipe on one date, and the chain's own current figure, read by you, is the better source. The assistant may recognise an item from its own knowledge; that recognition is something to compare with the board, not a reading of it.
Where a chain publishes macros, say them and they are kept; where it publishes only calories, the macros are estimated and the item says so. Either way the source is on the item, and a week later you know that Tuesday's lunch was a printed figure and Wednesday's a plate nobody weighed.
How do you log a fast food meal from the board?
IZeat is the calorie tracker inside ChatGPT, Claude or any other assistant. Tell the assistant you already use what you ate instead of searching for foods and entering them one by one. A meal with the figure printed for you is the simplest case for the record, and it still says which part was declared and which was reasoned, which is what keeps it worth keeping while you work toward your goal.
Saturday, 13:10, at a coffee chain: "A large latte and a blueberry muffin, the board says 190 and 420, whole milk." The assistant keeps 190 and 420 as read, estimates the macros from the items, and records two items through IZeat, each as an estimate that quotes the board, with the milk in your words. The receipt comes back: the two rows with their figures, the meal total, the day so far and, once you have set a target, what is left. Had the board printed nothing, the assistant would have asked the size and the milk first, and recorded the estimate that followed.
- You keep the figure the chain printed. A printed calorie is the chain's declaration for its standard item; say it and it is kept as read, and if the assistant knows the item differently, it says so instead of replacing your reading.
- You know which part of the meal was declared and which was reasoned. The item says it was recorded as an estimate that quotes the board, so the week does not look more certain than it was.
- You add what the menu left out, in a sentence. The sauce, the larger size, the half you did not eat: said in your words, recorded as their own items or as your portion, and the day follows.
The limit, plainly: IZeat holds no chain's figures and looks nothing up; what you read is what is recorded, and what the board does not print is the assistant's estimate, marked as one. If you want a database of every chain's menu, the chains publish theirs; if you want a record that says where each item's numbers came from, this is it.
Frequently asked questions
Short answers to the questions people type, each one sourced above.
Are the calories on a menu accurate?
They are the chain's declaration for a standard item, of the same kind as a packaged label, and required by law for large chains in the United States and England. They are not a measure of the portion you were served, which can be larger, smaller or sauced differently, and they rarely include the drink or the sides. A printed figure is the starting point, not a measurement of your meal; say what was not standard, and the record carries the difference as your words.
Do menu calories include the sauce, the sides and the drink?
Rarely. The figure printed beside an item is for that item as a standard portion; fries, a drink and a sauce are usually printed separately or not at all. Say them as their own items: "medium fries at 320, a cola at 210, and I added a sauce". The printed figures are kept as read; the sauce is estimated and says so; and the meal total is the sum of what you actually had, not of what the menu happened to list.
Why do menus print calories but not macros?
Because the law requires the energy figure and not the rest: calories for standard items in the United States, kilocalories per portion in England. Some chains publish macros on their own sites and calculators; most boards do not. So a menu item recorded from the board has a declared calorie figure and estimated macros, and since an item carries one source, it is recorded as an estimate that quotes the board, with the printed calories kept as read.
Does IZeat have McDonald's calorie calculator built in?
No, and no chain's database: IZeat looks nothing up. The chains' own calculators are their declarations, and the figure you read there is the best source there is for that item; say it to your assistant and it is kept as read. The assistant may recognise an item from its own knowledge, which is something to compare with the board, not a reading of it. What IZeat adds is the record: the item with its figure and its source, the day so far, what is left.
How do I log a meal deal or a combo?
Item by item, with the figures the board gives for each: the burger, the fries, the drink, each kept as read, each its own line, so that a drink swapped for water or fries left half-eaten changes the record the way it changed the meal. If the board prints only a combo total, say the total and the items, and the assistant records the items as an estimate that quotes the combo figure, saying so.
What if the restaurant prints no calories?
Then it is a restaurant plate like any other, and the three questions do the work: what the dish was, about how much, and what it was cooked in. Under IZeat's protocol the assistant asks what your words left open, in one message, then records an estimate marked as one. A chain below the legal threshold, an independent place and a food stall are all in this case, and the record says so beside the meals that had a printed figure.
Is a photo of the menu board enough?
Yes, for the figures: the assistant reads the printed calories from the photo, echoes what it read so a misread is caught, and keeps them, as it would if you read them out. It is not enough for the portion or the extras, which the board cannot show; say the size you had and what you added. A photo of the tray is different: it names the food and shows neither the size nor the sauce, so the questions are asked before any number.
Do the calorie rules apply outside the United States and England?
This page records the two it has read: the FDA rule for chains with 20 or more locations, in force since 7 May 2018, and England's regulations for businesses with 250 or more employees, since 6 April 2022. Rules differ elsewhere, and a chain may print figures where no law requires it. Wherever a figure is printed, the same path applies: read it, say it, and it is kept as read; where none is, the three questions apply.
