Does caffeine make us have more energy even though it doesn’t have many calories? Does it make our bodies use up fat that is already stored? Where does the extra energy from caffeine come from?

Caffeine just prevents you from being able to tell that you’re tired by blocking certain receptors in your brain, and gives you a shot of adrenaline.
Adrenaline has the effect of redirecting blood flow and increasing blood sugar levels, since it’s used to prepare you to fight or run from threats.
So, it doesn’t give you energy. It just makes you feel like you’re less tired, and puts your body in an excited state.
