Answer 1

Caffeine conveniently fits into adenosine receptors in the brain, blocking the body’s ability to feel fatigue. It only masks it, though — it doesn’t actually provide energy in and of itself. Consider, however, that most people don’t drink their coffee black. Instead, they add cream, sugar, chocolate, whipped cream…the list goes on! Those will give *some* energy but probably nothing significant.
