Don't order the biggest size. The biggest size means cheaper, but it is not good for your health. The biggest size has the most fat, sugar and so on. A smaller size is probably enough for you.

Some drinks are full of sugar. So when you want something to drink, you should choose milk or water.

Usually fried food is not the best choice. You should choose baked (烘烤的) food. It is healthier.

Go for the kids' menu, because the sizes of kids' food are usually smaller. You can eat less. You can also choose to eat half of what you order and take the other half home to eat later.

Today, more and more fast food restaurants are starting to serve healthier food. You can order the food with words like "healthy "or" light (清淡的)" on the menu.
