Healthy eating doesn't just mean what you eat, but how you eat. Here is some advice on healthy eating.
Eat with others. It can help you to see others' healthy eating habits . If you usually eat with your parents, you will find that the food you eat is more delicious.
Listen to your body. Ask yourself if you are really hungry. Have a glass of water to see if you are thirsty—sometimes you are just thirsty, you need no food. Stop eating before you feel full.
Eat breakfast. Breakfast is the most important meal of the day. After you don't eat for the past ten hours, your body needs food to get you going. You will be smarter after eating breakfast.
Eat healthy snacks like fruits, yogurt or cheese. We all need snacks sometimes. In fact, it's a good idea to eat two healthy snacks between your three meals This doesn't mean that you can eat a bag of chips instead of a meal.
Don't eat dinner late. With our busy life, we always put off eating dinner until the last minute. Try to eat dinner at least 3 hours before you go to bed. This will give your body a chance to digest most of the food before you rest for the next 8-10 hours.
