Whether working or working out, these guidelines will be useful in helping you plan meals and snacks to increase energy and sustainability.

Pre-exercise Meals

  • Carbohydrate meals help fuel muscles and prevent depletion of glycogen stores. Glycogen is the body’s main form of stored carbohydrates; it is a main source of energy during work and exercise. You should choose complex carbohydrates like fruits and whole grains to help sustain energy levels for long-duration activities. Try to avoid high-sugar foods such as soda and candy, as these cause high peaks in blood sugar and tend to give you a quick burst of energy that soon fades away.
  • Watch high-fat foods—they are hard to digest and may cause an upset stomach during high-intensity exercise. In comparison to carbohydrates, high-fat and high-protein meals take longer to digest and therefore require more energy for their breakdown.
  • Try to have a meal with complex carbohydrates four hours prior to exercise and a small snack one or two hours before exercise.


Whole-grain cereals, yogurt, whole-wheat pasta, fruit, whole-grain bagels, oatmeal, raisins, some energy bars (check that they are not too high in fat or protein).

Post-exercise Meals

  • Your muscles need to recover after exercise, as this is when your metabolism is at its peak.
  • Refueling should begin within 30 to 45 minutes after exercise to restore glycogen and repair muscle tissue.
  • Carbohydrates and protein will enhance the process of rebuilding and repairing muscles.

Remember to stay hydrated! Dehydration slows your metabolic rate by 2% and can also leave you feeling sluggish. Feel your best by drinking at least eight to ten 8-ounce glasses of water daily!
