Eating out while losing weight: dietitian's guide to read the menu

Eating out can be challenging when you're trying to lose weight or improve your eating habits. Restaurant menus often include rich sauces, fried foods and large portions, making it difficult to know what to choose.
But healthy eating doesn't mean avoiding restaurants or only ordering salads.
As a Registered Dietitian in Northampton, I help clients develop realistic approaches to weight management and healthy weight loss without giving up the foods they enjoy. One of the most important skills is learning how to make balanced choices when eating out.
Here are some simple tips to help you navigate a restaurant menu with confidence.

Choose the Right Cooking Method
One of the easiest ways to make a healthier restaurant choice is to look at how the food is cooked.
Grilled, baked, roasted, steamed and lightly pan-seared dishes are generally better choices than deep-fried foods.
Deep-fried dishes such as squid, arancini and fries can contain considerably more calories because of the oil absorbed during cooking.
If you're working towards weight loss, choosing grilled or baked options can be a simple way to reduce the overall calorie content of your meal without feeling like you're restricting yourself.

Be Mindful of Creamy Sauces
Creamy sauces can turn an otherwise balanced meal into a much heavier option.
For example, a tomato-based pasta is generally a lighter choice than pasta made with a cream-based sauce.
This doesn't mean you need to avoid creamy pasta altogether. Weight management is about your overall eating pattern, rather than labelling individual foods as "good" or "bad."
If you choose a creamy dish, consider having a smaller portion or balancing it with vegetables or a salad.

Include a Good Source of Protein
When choosing a meal, ask yourself:
"Where is the protein?"
Protein can help you feel satisfied after eating and is an important part of a balanced diet.
Good restaurant choices include:

• Grilled chicken
• Fish and seafood
• Salmon
• Lean steak
• Lamb
• Chicken skewers
• Eggs
• Beans and lentils
• Greek yoghurt or tzatziki

For example, a vegetable salad may be nutritious but might not keep you satisfied if it doesn't contain enough protein. Adding chicken, fish, eggs or another protein source can make it a much more filling meal.

What Should You Choose When Ordering Pasta?
Pasta can absolutely be part of a healthy weight-loss diet. The sauce, ingredients and portion size are often more important than the pasta itself.

Tomato-based pasta
Tomato-based sauces are generally a lighter option than cream-based sauces.
Look for pasta dishes containing tomatoes, vegetables and a protein source such as chicken, prawns or fish.

Creamy pasta
Cream-based pasta dishes can be higher in calories and saturated fat.
If creamy pasta is what you really want, you don't have to avoid it. Consider the portion size and think about what else you're having with the meal.
Remember: healthy weight management isn't about eating perfectly at every meal.

Choosing Meat and Fish When Eating Out

Salmon
Salmon is an excellent source of protein and unsaturated fats.
However, the way it's prepared can make a significant difference to the overall meal. Pan-seared salmon served with a creamy sauce and buttery potatoes will be considerably more energy-dense than grilled salmon served with vegetables or rice.

Lamb
Lamb provides protein and iron and can be a nutritious addition to your diet.
Some cuts can be higher in fat than chicken, so consider the overall meal when making your choice.
For example, if your lamb dish comes with both mashed potato and pita bread, you could choose one rather than having both.

Chicken
Chicken breast is often a relatively lean protein choice, particularly when grilled.
Chicken skewers with peppers, onions and tzatziki can make an excellent balanced meal. Add a small portion of bulgur rice if you'd like some additional carbohydrate.

Steak
If you enjoy steak, there's no reason to avoid it when trying to lose weight.
Instead of automatically choosing fries, consider boiled potatoes, rice or vegetables as your side.
Small changes like this can make restaurant meals easier to fit into a weight management plan.

Can You Eat Pizza When Trying to Lose Weight?
Yes!
Pizza doesn't need to be excluded from your diet if you're trying to lose weight.
Instead, consider the toppings.
Vegetable toppings such as mushrooms, peppers and other vegetables can increase the nutrient and fibre content of your meal.
A simple pizza with tomato sauce and buffalo mozzarella can also be a reasonable option.
Pizzas containing several types of cheese, such as quattro formaggi, are likely to be higher in fat and calories.
Processed meats such as pepperoni, ham and sausages can also be high in saturated fat and salt. These foods are best enjoyed occasionally as part of an overall balanced diet.
And remember: vegan doesn't automatically mean lower calorie or healthier. Some vegan cheeses are highly processed and can be high in saturated fat.

Don't Forget About Portion Sizes
Portion size is particularly important when eating out.
Restaurant portions can sometimes be much larger than the amount you would normally eat at home.
Even nutritious foods can contribute a significant amount of energy when eaten in very large portions.
You could consider:

• Sharing a starter or dessert
• Choosing a smaller portion where available
• Taking leftovers home
• Ordering vegetables or salad alongside your main
• Stopping when you're comfortably full rather than automatically finishing everything

There is no need to leave the restaurant feeling overly full simply because the food is there.​

What About Restaurant Sides?
Sides can sometimes add more calories than we realise.

Fries
Because fries are deep-fried, they can significantly increase the calorie content of a meal.

Mashed potatoes
Mashed potatoes can be a good carbohydrate choice, but restaurant versions may contain substantial amounts of butter or cream.

Rice or boiled potatoes
These can be useful alternatives if you're looking for a lighter side.

Salad
A salad can be an excellent way to add vegetables and fibre to your meal.
However, be aware that creamy dressings, large amounts of cheese, oil and other toppings can significantly increase the calorie content.
If you're ordering a salad as your main meal, make sure you include a source of protein to help keep you satisfied.

The Best Diet for Weight Management Is One You Can Maintain
When you're trying to lose weight, it's easy to become focused on finding the "perfect" meal.
But successful weight management isn't about making perfect choices every time you eat.
It's about developing habits that you can maintain long term.
​
When looking at a restaurant menu, try asking yourself:
1. How is it cooked? Grilled, baked and roasted options are generally lighter than deep-fried foods.
2. Does it contain protein? Protein can help make your meal more satisfying.
3. What are the sides? Do you need fries, bread and a creamy sauce, or would one or two be enough?
4. How large is the portion? Consider whether the restaurant portion is more than you actually need.
5. Will I enjoy it? Food should be enjoyable. Don't choose a meal you dislike simply because you think it's the "healthiest."
