Eat mindfully - take your time at meals. Put your fork down after each bite. You will most likely find yourself eating less. Another trick is to make eye contact with each person at the table after each bite or drink of beverage.
Avoid genetically modified foods - corn and soy are the biggest culprits. Try to buy these foods only organic.
Move - incorporate movement into your entire day. If you struggle with finding a block of time to work out, try to move as much as possible throughout the day. Don't avoid the stairs and long walks to your car.
Cut down on dairy.
