    It's considered to be the most important meal of the day, but do you really take the time to put together a healthy meal first thing in the morning? If you're watching your weight, skipping breakfast will damage your efforts to lose weight____ It can also speed up your metabolism (新陈代谢).

    Making breakfast a habit may not be easy. Use these tips to make eating breakfast a habit:

    Get up earlier____ Get up ten to fifteen minutes before your regular wake-up time that you have enough time to prepare a tasty meal before your day begins. Try to make time to include breakfast in your daily schedule and stick to it so it becomes a habit.

    Plan your meals ahead of time____ Put together three or four different breakfast recipes that you know you will actually eat. A little planning can help you make eating breakfast a habit as soon as possible.

    Be selective. Buy a handful of ingredients to put together a healthy breakfast yourself, instead of relying on prepared breakfast food and snacks____ If you don't like “traditional” breakfast foods, eat what you like so that you're willing to stick with it to make eating breakfast a habit.
