Your brain uses about 20% of your body’s energy

The brain is only about 2% of body weight, yet it burns roughly one-fifth of resting calories — a greedy organ for its size.

Billions of neurons spend energy firing, resetting ion gradients, and maintaining networks even when you “do nothing.”

Thinking is expensive metabolism. Feed and rest the brain like the high-demand machine it is.
