Follow the healthy eating rules

According to Pav Kalsi, Clinical Director, Planet Nourish, a change in your usual routine and diet need not have an effect on diabetes control.

"It can be balanced by adjusting the amount - and timing - of any insulin that you take, she says. "Talk to your healthcare team about how to adjust your dose."

If you're not taking insulina, you can manage your diabetes by sticking to the healthy eating principles you normally follow at home. This means picking the most nutritious foods, the healthiest preparation methods and the right portion size. It may be trickier when you're not doing the cooking, but it's still possible to manage.

Planeje com antecedência

Most restaurants and cafés publish their menu - or a typical example - on their website. Take a look before you book and check there are dishes you can enjoy. Many publish all the nutritional data too, so you can monitor calories or carbs if you're trying to lose weight, so you can adjust your insulin.

Ask questions

Good waiting staff will be trained to answer any queries about ingredients or preparation. Don't be shy about asking what cooking methods are used - for example, if salt or fat is added.

Watch your carbs

You may already use a carbohydrate counting app, or be familiar with the carbohydrate content of different foods. But it can be harder to do this when you're eating out and have more options on offer. Choose healthier carbs such as grãos integrais and legumes, and limit refined grains, and processed and sugary foods.

Watch your fat

Limit saturated fat where you can - such as in sauces, dressings, fatty cuts of meat, and fried foods. It's high in calories, which can contribute to weight gain and raise colesterol, increasing your chance of developing doença cardiovascular. Ask staff about healthier, unsaturated alternatives, or ask for sauces and dressings on the side.

Fill up with vegetables

For a balanced meal, include a good portion of vegetables and some lean protein - such as chicken, fish, legumes, or tofu. This can help you to feel fuller for longer, and you'll be less likely to overeat.

The UK government's Eatwell Guide suggests one third of your plate should be vegetables, while a portion of protein should be about the size of your palm.

Look out for hidden sugar and salt

Many salad dressings, marinades and sauces can be high in sugar and salt, so ask for them on the side and just have a small amount. You could also substitute dressings for vinegar or lemon juice.

Desserts tend to be high in sugar too, so share with a friend or have fresh fruit if it's an option. Fruit can also be quite high in sugar, but is generally better for you as it contains a range of healthy nutrients, and is not absorbed as quickly as refined sugars.

Drink wisely

A regular-sized sugary fizzy drink can contain around 10 teaspoons of sugar but restaurant portions can be bigger, so it's better to go for sugar-free or diet versions. Juices and smoothies can be equally high in sugar, as are many alcoholic drinks.

Don't forget to add any drinks to your carb count, or make drinking water more interesting with ice, sparkling options, and fruit slices.

Watch your portion sizes

Restaurant portions sizes tend to be larger than those at home. If you know a restaurant likes to 'supersize', ask for a starter as a main, go for a kids' portion, or split a meal with a friend.

Don't feel the need to clean your plate either. Try to eat slowly and mindfully, listen to your body and stop when you're full. If you're watching your weight, take care not to fill up on bread, bar snacks or sharing platters, too.
