Trying to stay healthy seems to be a difficult thing for us. To have healthy lifestyle, there is no (good) way than to encourage the whole family to have a healthy lifestyle.
When others do the same (activity) as us, we can encourage each other to keep doing. If get your family to be interested in doing exercise and eating (healthy), you will be fit and healthy quicker than you think.
When you go shopping, only buy healthy food. Buy vegetables and fruit rather than junk food like chips. Try different kinds of foods and try (eat) more at home.
Don't think food as some kinds of entertainment(娱乐). We may often meet our friends for lunch. In fact, there are many other things you can do with friends. How about (meet) friends for a football game rather than meeting for lunch? You can still eat, the activity doesn't have to focus(集中)on food. The food is less important than the fun activity.
Looking after your health should not be boring. (start) now.
