Ditto... You basically have to change your habits and/or lifestyle. If you go to Jack in the Box, get a salad instead of the Jumbo Jack, if you cook at home use veggie oil and not lard (don't ask). There is a plethora of information online about different foods, but if you don't get off you butt and read a little and act then it doesn't really matter.
