I always get tired around 4:00pm every day. What can I do to increase my energy levels?

The mid-afternoon 'slump' could be caused by a number of reasons. One of the most common reasons is that your blood sugar is dropping due to the digestion of your lunch. If you think that a normal meals takes about 4 hours to digest, it makes perfect sense that our bodies would be ready for more food mid-day. Try incorporating an afternoon snack around 3:30 and see if it helps keep you on track until dinner time.  Usana Bar are perfect for this time - they have a perfect amount of calories to carry you through until dinner and have a balance of carbohydrates and protein to get your blood sugar back in balance.
