FEELING FOGGY? If you're finding it hard to concentrate and feel like your mind is a pile of goo, you may want to snack on some protein-rich foods. Foods like cheese, soy products and lean meat are great for making you feel alert, energized and ready to take on the day. So if your brain's feeling a bit foggy, just nibble on some low-cal string cheese, a veggie burger, or some lean skinless chicken or turkey breast. You may be thinking more clearly in no time.
