Yes, you need to try your best to keep yourself moving and flexible. You should try to make healthier choices when you are eating . Avoiding processed foods, "diet" foods, fatty foods and eating extra vegetables and fruits will help you to keep a natural, healthy balance within your body.
Remember though, every once in a while you have to cut loose and have some ice cream, drink some beer or whatever makes you happy. Keep in mind, anything in moderation and do your best to enjoy life!
Life is short so live it!
