How much energy does your brain burn? Your brain also uses energy to perform normal functions. Although it makes up 2 percent of your body weight, it burns 20 percent of the energy you consume. This metabolic activity is generally consistent, regardless of what you're doing. In fact, your brain burns more energy at rest than a human thigh while running.
Why does the brain consume so much energy?
The brain expends a lot of energy. While the organ accounts for only about 2% of a person's bodyweight, it is responsible for about 20% of our energy use at rest. The reason that learning consumes so much energy is that forming long-term memories requires neurons to produce new proteins.

What happens if you use more than 10 percent of your brain?
Studies of brain damage: If 10 percent of the brain is normally used, then damage to other areas should not impair performance. Instead, there is almost no area of the brain that can be damaged without loss of abilities. Even slight damage to small areas of the brain can have profound effects.
