Exercise. Another way which is always be ignored is to excercise more. An average of steps a normal adult have per day is 10000 - 15000. You'll find yourself more healthy after changing the steps to 15000 - 20000 per day, and you'll get more fit easily by that.
That's my own easy methods of staying healthy. I'll be glad if you have any ideas about that and have a discussion with me!
