Key points
- Restaurant food can fit a weight loss plan. How often you eat out, and what you usually order, matters far more than one special dinner.
- Meals out are usually large. Laboratory tests of popular restaurant meals in several countries found that most held at least 600 kcal, before drinks or dessert.
- Order protein first, then vegetables. Grilled, steamed, baked or roasted dishes with a side of vegetables or salad fill you up for fewer calories.
- Every cuisine has light and rich dishes. Sushi, pizza, Chinese, Indian, Middle Eastern, Mexican, Italian and Thai menus all offer good choices for weight loss.
- Frequent fast food is the clearest risk. A 15-year study linked fast food more than twice a week with extra weight gain over the years.
- Talk to your doctor first before you change your eating, especially if you have diabetes, high blood pressure, kidney disease or take regular medicines.
Does eating out make weight loss harder? What the studies show
Eating out can make weight loss harder, mainly because restaurant and takeaway meals tend to be bigger and richer than what most people cook at home. But the research points to the habit over months, not to a single evening, so a meal out now and then is not a problem.
A systematic review of 28 studies in adults looked at eating away from home and body weight. Almost all of the long-term studies, and about half of the snapshot studies, found that people who ate out more often tended to weigh more.
A second review focused only on studies that followed people over time. Frequent out-of-home eating went together with a higher risk of overweight and with weight gain, and meals from fast-food outlets were linked with a bigger rise in weight and waist size than meals at other restaurants.
Why restaurant meals add up
Researchers in Brazil, China, Finland, Ghana and India bought popular restaurant meals and measured the energy in a laboratory. Only in China was the average meal clearly lighter than in the United States, at about 720 kcal against roughly 1,090 kcal; elsewhere it was in the same high range.
Two details from that study are useful when you choose where to eat. Fast-food meals held about a third less energy than sit-down restaurant meals, so a nicer setting does not mean a lighter plate. And the number of parts on the plate, along with the meal’s weight, helped predict how much energy it held.
Our page on portion control explains what this means for the size of your plate. Here we focus on what to choose from the menu, cuisine by cuisine.
Why it is not only willpower
Restaurants are built to make food tempting: the smell, the photos on the menu, the offers to add a side or upgrade a size. Finding that hard is normal. Our page on the food environment explains how surroundings shape what we all eat.
That is why a few habits you decide on beforehand work better than trying to resist in the moment. You make the important choices when you are calm and not yet hungry.
Before you go: plan the meal, not a day of hunger
The best preparation for a meal out is to eat your normal meals earlier in the day and to have a rough idea of what you will order. Arriving very hungry makes it much harder to choose well when the menu arrives.
Skipping lunch to “make room” for dinner can backfire. Hunger builds through the afternoon, and by the time the bread or the crisps reach the table, the first course has started before you ordered it.
- Eat your usual breakfast and lunch, each with some protein, such as eggs, yoghurt, fish, chicken or beans.
- Have a small snack late in the afternoon if dinner is late, such as fruit, a yoghurt or a few vegetable sticks.
- Look at the menu online and pick one or two dishes that fit your plan, so you do not decide while hungry.
- Drink a glass of water before you leave and keep drinking water with the meal.
- Walk there, or walk afterwards, if it is safe and the distance suits you. It turns the outing into part of your active day.
If you have diabetes or take medicines that lower your blood sugar, do not skip meals before eating out without advice. Ask your doctor or diabetes nurse how to time your meals and medicines on days with a late or large dinner.
Choosing the place
When you can choose, pick a place where you already know a dish you enjoy that also fits your plan. Menus with grilled dishes, soups, salads with a protein, and vegetable sides make the evening easy.
All-you-can-eat buffets are the hardest setting for most people, because there is no natural end to the meal. You do not have to avoid them forever, but they are easier when your new habits have had a few months to settle.
How to order for weight loss: protein first, then vegetables
To order for weight loss, start by choosing your protein, then add vegetables or salad, and only then decide on the carbohydrate side and the sauce. Protein and fibre fill you up, so this order of thinking keeps the meal satisfying without making it heavy.
- Pick the protein: fish, chicken, lean meat, eggs, beans, lentils, tofu or seafood. Grilled, baked, roasted, steamed or poached is usually lighter than fried.
- Add vegetables: a side salad, steamed greens, grilled vegetables or a vegetable soup. Ask whether you can swap fries for a vegetable side.
- Choose the starch: rice, potatoes, pasta, bread or flatbread can fit; just pick one, not three.
- Ask for the sauce on the side: creamy sauces, dressings and mayonnaise carry a lot of energy, and serving them yourself lets you use less.
- Order the drink last: water, sparkling water or another sugar-free drink.
For more ideas on the first step, see our guide to meat and fish for weight loss. If vegetables are a hard sell for you, our page on vegetables and legumes has easy places to start.
Menu words to look for and words to watch
Menus often tell you how a dish is cooked, and that tells you a lot about its energy. Use the words below as a quick guide; they are rules of thumb, not guarantees.
| Menu word | What it usually means | Lighter choice if you want one |
|---|---|---|
| Grilled, roasted, baked, chargrilled | Cooked with little added fat | A good choice as it is |
| Steamed, poached, boiled | Cooked in water or steam, no frying | A good choice; add a light sauce |
| Stir-fried, sautéed | Cooked in some oil; amount varies a lot | Ask for less oil, extra vegetables |
| Crispy, crunchy, battered, breaded, tempura | Deep-fried in a coating | The grilled or steamed version |
| Creamy, cheesy, au gratin, alfredo | Cream, butter or cheese sauce | A tomato-based or broth-based sauce |
| Loaded, stuffed, smothered, double | Extra cheese, sauce or meat on top | The standard version, sauce on the side |
| Glazed, sticky, sweet and sour, honey | A sugary sauce, often on fried pieces | A savoury or spicy sauce, not fried |
| Bottomless, unlimited, combo, meal deal | More food or drink for a small extra price | The single item and water |
Some menus show calories next to each dish. A Cochrane review pooled three restaurant trials and found that calorie labels on menus lowered the energy people bought by about 47 kcal per meal, based on low-quality evidence. A small help, then, but worth glancing at when the information is there.
Restaurant calorie figures are estimates, and real dishes can contain more. Our page on calorie counting explains how accurate menu numbers tend to be and how to log a meal out without stress.
Is sushi good for weight loss? Best and worst choices
Sushi can be very good for weight loss, especially sashimi, nigiri and simple rolls with fish or vegetables. Rolls with tempura, mayonnaise or cream cheese are much richer, and the rice and soy sauce add up when you order a lot of pieces.
The appeal for weight loss is clear: fish gives you a lot of protein for its calories, the portions come in pieces you can count, and there is little hidden fat in the classic dishes. The catch is that many modern rolls are closer to a deep-fried snack than to a plate of fish and rice.
Sushi compared: approximate calories and protein
The figures below are our own estimates, built from USDA food composition data for the separate ingredients. Sushi sizes differ a lot between restaurants, and seasoned sushi rice contains a little sugar, so treat these as rough guides.
| Sushi | Portion (estimate) | About kcal | About protein | For weight loss |
|---|---|---|---|---|
| Tuna sashimi | 6 slices, 90 g fish | 100 | 22 g | Best: almost pure protein |
| Salmon sashimi | 6 slices, 90 g fish | 185 | 18 g | Very good: protein and healthy fats |
| Tuna nigiri | 2 pieces | 85 | 8 g | Very good |
| Salmon nigiri | 2 pieces | 115 | 7 g | Very good |
| Cucumber roll | 6 pieces | 135 | 3 g | Light, but little protein |
| Tuna roll | 6 pieces | 165 | 10 g | Good |
| Salmon and avocado roll | 6 pieces | 225 | 9 g | Good in moderation |
| Tuna roll with spicy mayonnaise | 6 pieces | 230 | 10 g | Ask for less sauce |
| Salmon and cream cheese roll | 6 pieces | 280 | 10 g | Richer: an occasional choice |
| Fried shrimp (tempura-style) roll with mayonnaise | 6 pieces | 295 | 11 g | Richest: an occasional choice |
| Edamame (soybeans in the pod), beans only | 100 g | 120 | 12 g | Good starter: protein and fibre |
Source: USDA SR Legacy, approximate values rounded to the nearest 5 kcal. Our assumptions: plain cooked rice, 20 g per nigiri piece and 100 g per six-piece roll; 15 g of fish per nigiri, 30 g of fish or 40 g of fried shrimp per roll; 20 g avocado, 25 g cream cheese or 10 g mayonnaise where used.
How to build a sushi meal that helps you lose weight
- Start with soup or edamame. A miso soup or a bowl of edamame takes the edge off hunger before the rolls arrive.
- Make sashimi or nigiri the core. They give the most protein for the fewest calories.
- Choose one roll you love, and let the rest be simple fish or vegetable rolls.
- Add a seaweed or cucumber salad for volume and crunch.
- Count your pieces before you order, rather than adding plate after plate on a conveyor belt or a set price menu.
- Go easy on soy sauce. It is very salty; dip the fish side lightly, or use a reduced-salt version if you have high blood pressure.
Rice is not the enemy here. It is simply the part that grows fastest when you order many rolls, which is why sashimi and nigiri make the meal lighter. Our page on carbs and weight loss explains how rice fits into a plan.
If you are pregnant, have a weakened immune system or have been told to avoid raw fish, choose cooked options such as cooked prawn, eel, egg, tofu or vegetable rolls, and ask your doctor or midwife what is safe for you.
Is pizza good for weight loss when you eat out?
Pizza is not a weight loss food, but it can fit into a weight loss plan when you eat a modest amount and add something filling alongside it. The problem is usually the whole pizza, the extra cheese and the garlic bread, not one or two slices.
A plain cheese pizza from a takeaway is about 265 kcal per 100 g, according to USDA data, with around 11 g of protein. Gram for gram, the thin-crust version is not lighter: it came out at about 300 kcal per 100 g, because the toppings make up more of each bite.
That surprises many people. A thin crust only saves calories if you end up eating fewer or smaller slices, so let the number of slices guide you rather than the type of base.
| Pizza | About kcal per 100 g | About protein per 100 g |
|---|---|---|
| Meat and vegetable topping, regular crust | 245 | 11 g |
| Cheese topping, regular crust | 265 | 11 g |
| Cheese topping, thin crust | 300 | 13 g |
| Pepperoni topping, thin crust | 330 | 14 g |
Source: USDA SR Legacy, values for generic takeaway pizzas, rounded. Your local pizza may differ; slice sizes vary even more.
A pizza night that still helps you lose weight
- Start with a large salad with a light dressing, or a vegetable soup, so you are less hungry when the pizza arrives.
- Decide on your slices before the box opens. Two slices with a big salad is a realistic, filling meal for many people.
- Choose vegetable toppings, such as peppers, mushrooms, onions, spinach or tomatoes, with chicken, tuna or prawns if you want more protein.
- Ask for normal cheese, not extra cheese or a stuffed crust.
- Skip the garlic bread and dips; they can add as much as another slice or two.
- Share a pizza rather than ordering one each, and put leftovers in the fridge before you sit down.
Pasta on a restaurant menu follows the same logic. A tomato-based sauce with fish, chicken or vegetables, and a starter-sized portion with a salad, is a good fit for weight loss; creamy sauces and a very large bowl are the dishes to keep for now and then.
Chinese, Indian, Middle Eastern, Mexican, Italian and Thai food for weight loss
Every cuisine has dishes that suit weight loss well, and every cuisine has richer dishes for celebrations. The trick is not to avoid certain cuisines, but to know the lighter classics on each menu and how to spot the dishes cooked in a lot of oil, cream, cheese or sugar.
Many of these traditions are built on vegetables, beans, lentils, fish and grilled meat, which are exactly the foods that fill you up for fewer calories. Menus outside a dish’s home country, and takeaway menus in particular, sometimes lean more on fried and sweet versions, so it helps to look past the first page.
| Cuisine | Lighter picks | Watch-outs | Why it helps weight loss |
|---|---|---|---|
| Chinese | Steamed fish or dumplings, stir-fried chicken, prawns or tofu with vegetables, clear soups, plain steamed rice | Battered pieces in sweet sauces, fried rice and fried noodles, deep-fried starters | Lots of vegetables and lean protein, with the rice portion in your hands |
| Indian | Tandoori or tikka dishes from the clay oven, dal, chickpea and vegetable curries, raita, plain rice or a plain flatbread | Cream- or butter-rich sauces, fried starters, flatbreads brushed with butter, large rice portions | Pulses and spices give flavour and fibre without needing much fat |
| Middle Eastern | Grilled kebabs, chicken or fish, lentil soup, tabbouleh, fattoush and other salads, a modest scoop of hummus | Large flatbreads, fried falafel in big portions, dips heavy with oil, syrupy pastries | Grilled protein with salads and pulses makes a filling, balanced plate |
| Mexican | Grilled chicken, fish or beef with salsa and beans, soft tacos, fajitas with plenty of vegetables, black bean soup | Cheese-filled dishes, sour cream, fried shells, the basket of tortilla chips | Beans and salsa add fibre and taste for very few calories |
| Italian | Minestrone, grilled fish or chicken, tomato-based pasta in a starter size, salads, grilled vegetables | Cream and cheese sauces, garlic bread, large pasta plates, fried starters | Tomato sauces and vegetables are light; portion size is the main lever |
| Thai | Clear soups, grilled meat or fish salads, stir-fries with vegetables, fresh (not fried) spring rolls, steamed rice | Coconut-milk curries in large bowls, fried noodles and fried rice, deep-fried starters, sweet dipping sauces | Fresh herbs, chilli and lime give big flavour with little fat |
The watch-outs are not forbidden. A creamy curry or a cheesy enchilada can be part of a good week; just let it be the dish you chose on purpose, and build the rest of the meal around vegetables, soup or salad.
Same menu, very different choices
The USDA food database includes dishes as they are served in restaurants. Comparing them shows how much the cooking style matters, even within one menu.
| Menu | Lighter dish | About kcal / protein | Richer dish | About kcal / protein |
|---|---|---|---|---|
| Chinese | Chicken and vegetables | 95 / 8 g | Sweet and sour chicken | 250 / 10 g |
| Chinese | Shrimp and vegetables | 80 / 6 g | Battered orange chicken | 260 / 14 g |
| Chinese | Plain cooked white rice | 130 / 2 g | Fried rice without meat | 175 / 4 g |
| Italian | Spaghetti with tomato sauce | 105 / 4 g | Lasagna with meat | 185 / 11 g |
| Mexican | Soft taco with chicken | 190 / 13 g | Cheese quesadilla | 370 / 16 g |
| Mexican and Latin | Black bean soup | 105 / 5 g | Refried beans | 155 / 7 g |
Source: USDA SR Legacy, mostly restaurant dishes as sampled in the United States (plain rice and the chicken taco are general entries), rounded. Recipes and portions differ by restaurant and country. A main course often weighs several times 100 g, so the gap per plate is larger than the table shows.
Notice that the lighter dishes are usually the ones with vegetables in the name. They take up space on the plate and in your stomach for very few calories, which is exactly what helps you feel full and still lose weight.
Dressings, oils and nuts
Oil, nuts, seeds and avocado are healthy fats, but they are also dense in energy. A salad can become one of the richest dishes on the table with a generous dressing. Our page on nuts and healthy fats explains how to enjoy them in amounts that still let you lose weight.
If your doctor is watching your cholesterol, the same choices help: grilled instead of fried, fish more often, and fewer creamy or cheesy sauces. Our page on cholesterol and weight loss covers this in more detail.
Fast food, burgers and takeaway: how often and what to pick
Fast food and takeaway can fit into weight loss now and then, but how often you have it matters more than any single order. The clearest research links frequent fast food with gaining weight over the years.
A US study followed more than 3,000 young adults for 15 years. Those who went to fast-food restaurants more than twice a week, both at the start and at the end, gained about 4.5 kg more than those who went less than once a week.
They also had a twofold larger rise in insulin resistance, an early step towards type 2 diabetes.
A systematic review of 16 studies came to a similar conclusion and advised limiting fast food and making healthier menu choices easier. Most of these studies observed people rather than testing a change, so they show a strong link rather than proof, but the direction is consistent.
Burgers
A plain single hamburger is not the problem in a fast-food meal. According to USDA data, a basic single-patty hamburger with the usual condiments is around 265 kcal per 100 g, with about 13 g of protein.
The weight comes from what goes around it: double patties, bacon, extra cheese, special sauces, a large portion of fries at about 290 kcal per 100 g, and a large sugary drink. Choosing the single burger, a small side and water already changes the meal a lot.
- Choose a single patty or a grilled chicken burger rather than a double or a crispy one.
- Add salad, tomato and onion, and keep sauces to ketchup, mustard or a small amount of one sauce.
- Pick a side salad, corn or fruit instead of fries when you can, or the smallest fries on offer.
- Say no to the meal upgrade. A bigger size for a small extra price is a lot of extra food.
Making a delivery order lighter
Ordering in can be a relaxed evening without being a step back. A few small changes in the app or on the phone keep the meal satisfying.
- Choose your dish before you open the app, so the photos and offers have less pull.
- Add a vegetable dish to the order, such as stir-fried greens, a salad, a lentil soup or grilled vegetables.
- Order one carbohydrate side for the table rather than rice, noodles and bread for each person.
- Skip the free extras that come with the minimum order, such as crisps, sweets or a large soft drink.
- Serve onto plates and put the rest away before you eat.
Our weight loss recipes include home versions of takeaway favourites for the nights you would rather cook.
Drinks, the bread basket and dessert
Drinks, bread and dessert are often the easiest places to save calories at a restaurant, because you can cut them without changing the main meal you came for.
Drinks. Order water, sparkling water or another sugar-free drink with your meal, and keep refills of sweet drinks off the table.
Alcohol adds calories of its own and tends to loosen your plans for the rest of the meal. Our pages on weight loss drinks and alcohol and weight loss cover both in depth.
The bread basket. Bread, crisps or tortilla chips before the meal arrive when you are at your hungriest, and they are easy to eat without noticing. You can ask the staff not to bring them, take one piece and pass the basket on, or place it at the far end of the table.
Dessert. If you want dessert, choose the one you really love, share it, or order fruit, a sorbet or a coffee instead. Our guide to cutting sugar explains how to eat less added sugar without banning sweet things.
If you eat out often for work or family: a weekly pattern that still loses weight
If you eat out several times a week, a few standard choices and a simple weekly rhythm help you keep losing weight. When most of those meals are fairly light, the occasional richer one does not slow you down.
Work lunches are a good example. In the restaurant study from Finland, meals at worksite canteens held about a quarter less energy than meals from restaurants and fast-food places. If your work offers a canteen with a choice of hot dishes and salads, it is often the easier option.
Build your own “regulars”
- Find one go-to dish at each place you visit often, such as the grilled chicken salad, the fish of the day with vegetables, or the lentil soup with a side salad.
- Plan your week: if you know there is a business dinner on Thursday, keep the other evenings simple and home-cooked.
- Keep one richer meal a week for something you really enjoy, chosen on purpose rather than by accident.
- Keep moving. Walk to lunch, take a short walk after dinner, or keep your daily walk at a fixed time. Our walking for weight loss plan helps you build up gently.
- Watch late dinners. If evening meals out are often late, our page on eating late at night explains what the research says.
A simple restaurant day plan
| Moment | What to do | Why it helps weight loss |
|---|---|---|
| During the day | Normal meals with protein; a light snack if dinner is late | You arrive hungry but not ravenous |
| Before ordering | Look at the menu online and choose one or two options | You decide with a calm head |
| Ordering | Protein first, a vegetable side, sauce on the side, water to drink | A filling meal with fewer hidden calories |
| At the table | Skip or limit the bread, eat slowly, stop when comfortably full | You notice fullness before the plate is empty |
| After the meal | A short walk if it is safe and suits you | Movement turns the outing into an active evening |
| Next day | Your usual breakfast and walk, no “making up” for it | Your routine, not one meal, decides your progress |
Vacations, hotel breakfasts and festive meals bring their own challenges. Our page on holiday weight gain has a plan for those weeks.
Talk to your doctor first before you change the way you eat. This is especially important if you have diabetes or take medicines that lower blood sugar, if you have high blood pressure or kidney disease and need to watch salt, or if you have food allergies. This page gives general information, not personal medical advice.

Frequently asked questions
How many times a week can I eat out and still lose weight?
There is no fixed number that suits everyone. Studies link frequent fast food, more than twice a week, with more weight gain over the years, so once or twice a week is an easy starting point. If you eat out more often, for work or family, a few regular lighter dishes make the bigger difference.
Is a poke bowl or a sushi bowl good for weight loss?
It can be. A bowl with raw or cooked fish, tofu or chicken, plenty of vegetables and a normal portion of rice is filling and fairly light. Ask for half the rice with extra vegetables, choose a light dressing and go easy on mayonnaise-based sauces, fried toppings and extra avocado.
Should I order a salad every time I eat out?
No. A salad is only light if it has a modest dressing and no fried toppings, and many salads are not very filling. A grilled main with vegetables, a soup with beans or lentils, or fish with a side salad often keeps you full for longer and makes it easier to stop eating at the end of the meal.
Is it rude to ask for changes when I order?
No. Asking for sauce on the side, a vegetable side instead of fries, or grilled instead of fried is a normal request in most restaurants. Keep it short and friendly. If a dish cannot be changed, simply choose another one that is already close to what you want.
What can I eat at a work lunch or business dinner when I am trying to lose weight?
Choose a dish you would order anyway with a clear protein, such as grilled fish, chicken, beans or tofu, and add a vegetable side. Drink water or a sugar-free drink, and pass on the bread basket. Nobody needs to know you are losing weight; ordering calmly and enjoying the conversation is enough.
Do I gain weight after one big meal out?
Not in the way the scale suggests. A large, salty restaurant meal can raise your weight the next morning, but most of that is food and water that leaves within a few days. Fat gain comes from eating more than you need over weeks, so going back to your usual meals the next day is what matters.
