Modern science suggests that a healthy lifestyle matters much to how long you can live and how well you live.Here are some tips for you to form a healthy lifestyle.
Keep a scientific diet.Keep in mind that sugar can be removed(去除) from our diet completely.Over intake(摄入量) of sugar is one of the main reasons for getting fat.Over intake of protein(蛋白质) or fat and low intake of fiber can also lead to getting fat.Only a few grams of protein do we need every day to keep our body in order.Like rain to crops，not the more the better.
Be always in a good mood.There is a relationship between the mood and health.A good mood keeps you in high spirits.Thanks to the Internet，we can enjoy and learn much without going out.Take a look at some online shops and pick up some bargains，enjoy music and movies and chat with good friends.Just keep happy.
Enough sleep.Two studies show the reasons why teens and adults don't have enough sleep.With teens，a major reason is mobile phone use; with adults，it's work.Meanwhile，a third study of young children shows that lack of sleep in early life may lead to serious problems in future.Everyone needs at least 8hour sleep to recover from tiredness and the hurt caused by hard work in the daytime.
Proper exercise.Do exercise to keep away from fatness.Because of the quick pace of the modern life，you don't have time to do exercise every day，but at least three times a week and 45 minutes each time.
