The Brain
The human brain weighs approximately 1.4 kg (approximately four tubs of butter), is about the size of a grapefruit, is shaped like a walnut and can fit in the palm of your hand.
Though it weighs approximately 2 percent of your body weight, it consumes nearly 20% of our calories. Brain metabolism requires a large amount of energy.[youtube id=”XSzsI5aGcK4″]
