Does your brain burn calories?

Does thinking burn calories?

The human brain actually uses a lot of energy. How many calories does it burn?

At rest, the brain only burns about a tenth of a calorie a minute.

But when it is actively thinking, the brain burns up to 90 calories per hour! The brain can use up to 20% of the body’s total calories a day. That means that during a typical day, a person uses about 320 calories just to think!

The brain relies on glucose, a form of sugar, to complete the functions of thinking, learning and memory.

While reading, the average person burns 67 calories per hour!

When taking a test, the brain burns up to 270 calories per hour.

When playing chess, viewed as a sedentary game, the brain can burn up to 6000 calories in a day!
