Please explain yourself?
Caffeine is not a true source of energy but it is a cataylst for energy by reacting on certain receptors on the cellular level as well as in the brain. In the brain caffeine acts like a "blocker" of adenosine. The brain and pituitary gland react to "increased neuron firing" by dilating pupils, opening air passages, increased heart rate, vasoconstriction, etc. This is how the energy is created.
Now if you want to argue that carbohydrates are the only true source of energy that is debatable. Carbs alone do not create any energy unless work is invloved. Carbs can be stored as energy to be used later, but until it is used it is not energy.
I guess Starbucks, RB, Monster, et al have been pulling a fast one on us all these years and we didn't even realize it.
Whether you think can or think you can\'t, you\'re probably right!
