How to track a takeaway or restaurant meal

To track a takeaway, log it before you order, not after. Look up the chain's published calories where they exist, and where they do not, estimate generously and round up. A restaurant meal has no barcode and no label, so you are working from best guesses, and a guess that runs a bit high keeps you honest. Do it before the food arrives and you get to decide what fits your day while you can still change the order. Do it after and you are just writing down a decision you already made.

Here is how to do it well.

Start with published chain calories

Most big UK chains now show calories on their menus, in-store and online. Since 2022, large restaurant and takeaway businesses in England have had to display calories on menus by law. That gives you a solid starting number for a lot of the places you actually order from.

Order from a named chain? Pull up their menu online. The calorie figure next to each item is your log entry. No estimating needed.
Ordering through a delivery app? The listing often shows calories too, right under the item name.
Fettle (stayfettle.com) has many UK chain items in its food database, so you can often search the restaurant and dish directly rather than typing numbers in by hand.

Published figures are the closest thing to a food label you will get from a takeaway. Use them first, every time.

When there are no published numbers, estimate generously

Small independents, the local curry house, the chip shop on the corner: these rarely publish anything. Here you estimate, and the rule is simple. Round up, not down.

Restaurant food is cooked to taste good, which usually means more oil, more butter and bigger portions than you would use at home. Fat carries 9 kcal per gram, more than double protein or carbs, so a generous glug of oil in a stir-fry or a curry adds up fast and quietly. If you are unsure between two numbers, log the higher one.

A few rough anchors for a main-course portion:

A takeaway curry with rice often lands somewhere around 800 to 1,200 kcal, before any naan or side.
A large pizza can carry 2,000 kcal or more across the whole thing, so track it by the slice.
Fish and chips is commonly in the 800 to 1,000 kcal range for a standard portion.

These are ballparks, not label facts, which is exactly why you round up. An overestimate costs you a slightly smaller breakfast tomorrow. An underestimate is a deficit that quietly leaks all week.

Log it before you order

This is the part that changes results. Enter the meal in your tracker before you place the order, while you can still adjust it.

When the numbers are in front of you before you commit, you get real choices. Swap the rice for a smaller portion. Skip the second naan. Pick the grilled option over the fried one. Have the burger without the side. You are not depriving yourself, you are just seeing the trade before you make it, rather than after.

Logging after the meal turns the tracker into a diary of regret. Logging before turns it into a steering wheel. Same food database, completely different outcome.

Build the meal from its parts

When one entry does not exist for your exact dish, break the meal into components and log each one. A restaurant plate is usually a handful of separate things: a protein, a carb, a sauce, a side.

For example, a chicken curry becomes: a portion of chicken curry, a portion of rice, and a naan, each logged on its own. This is often more accurate than hunting for a single "chicken curry with rice and naan" entry that may not match your portion anyway. It also means you can see which part is the calorie-heavy one, which is usually the rice, the naan or the oil in the sauce.

Searching by component also plays to the strength of a food database, where individual ingredients and standard portions are far better covered than every possible restaurant combination.

A sensible routine for eating out

Pull this together and a takeaway stops being a black hole in your tracking:

Check for published calories first. Chain menus and delivery apps often have them.
No published number? Estimate, and round up when in doubt.
Log the meal before you order, so you can still change it.
Build unusual dishes from their parts rather than forcing one entry.

Eating out is not the enemy of tracking. Untracked eating out is. A rough number logged honestly beats a perfect number you never wrote down.

One honest note

The calorie ranges here are general estimates, not exact figures for any specific dish, and they are not medical advice. They suit most healthy adults tracking for general weight or fitness goals. If you have a health condition, are pregnant, or follow a specific eating plan for medical reasons, check with your GP or a registered dietitian before making changes.
