In the brain, gray matter refers to the darker, outer portion, while white matter describes the lighter, inner section underneath. Gray and white matter are two different regions of the central nervous system. What is the gray matter and white matter? It contains blood vessels and nerves, including neurons and glial cells. The remaining 40% is a combination of water, protein, carbohydrates and salts. Weighing about 3 pounds in the average adult, the brain is about 60% fat. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.

Simultaneously, the brain reduces its dopamine production for low-fat foods, devaluing the healthiest options. Tittgemeyer explains that when we have foods high in fat and sugar, 'the so-called dopaminergic midbrain', a region of the brain critical to controlling reward responses and motivational drive, gets activated.

In particular, activity in the dopaminergic system indicated that the reward circuits in the brain shifts to favor a high-sugar and high-fat diet.
