Energy and so-called "Energy Drinks"
"The Courier-Journal (Louisville, Ky.) printed a feature on energy drinks titled 'Liquid Energy.' Nancy Clark, R.D., FACSM, co-chair of ACSM’s Nutrition Interest Group provided expertise. 'If somebody is looking for energy, what they’re looking for is calories, and sure you can get calories in an energy drink,' Clark said. 'You can also get calories in a banana or yogurt or some orange juice.'" (emphasis added)

Note: Monster Absolutely Zero contains ZERO calories, in other words, ZERO energy! Energy drinks with, say, 100 Calories of energy provide no more true energy than a large apple. While energy drinks may contain some healthy additives that can help the body utilize already stored energy, the main perceived energy boost is almost certainly the result of the drug, caffeine, which gives the brain the illusion of increased energy.
