Caffeine can be an effective way to increase your energy in the short term. But you will eventually experience a caffeine crash that will undo the effects of your consumption of caffeine. A more effective approach is to ingest the right foods that can give you energy that will last you throughout the rest of the day.

Three servings of carbs is usually ideal because any more and you will stimulate the production of serotonin in your body.
Whole Grains, Meats, Cereals, Leafy Vegetables and Tofu

No More Alcohol, Sugar or Fatty Foods
Junk food and alcohol will kill your energy levels. Even if you think sugar will give you a boost in the short-term, the boost will be short-lived and you will find yourself crashing quickly. These foods not only make you tired in the short-term, but can also have a cumulative effect that will make very tired in the long-term. While you might think exercise can overcome your diet, without the right fuel, there is only so much you can do.
