As you learn more about incorporating good nutrition into your life, keep in mind that it's different than dieting. Implementing a nutrition plan is simply about making healthy food choices on a regular basis and being aware of how much you eat from certain food groups. You still get to enjoy a variety of delicious foods, and you shouldn't be left feeling hungry after a meal. When you combine good nutrition with being active, you'll have an excellent wellness plan in place.
