Answer 1

Caffeine does not directly provide us with energy, but it does make us more alert and able to stay awake for longer periods of time. Caffeine does not make our bodies use up fat that is already stored; instead it stimulates the central nervous system, which can make us feel more energized. The extra energy from caffeine comes from increased alertness and focus, as well as increased blood flow throughout the body. This can lead to improved physical performance and endurance.
