Motivation and the Brain
An individual’s motivation directly connects to his or her brain. For example, food deprivation creates a hunger drive, which pushes or motivates a person to seek, attain, and eat food (Deckers, 2010).

The hypothalamus has three main regions that are associated with hunger which are lateral hypothalamus, ventromedial hypothalamus, and periventricular hypothalamus.

Extrinsic, intrinsic, hereditary, and environment factors also have a great impact on maintaining a healthy diet ("Psychology of Eating Healthy", 2010).

Intrinsic factors, such as evolutionary, and genetic factors, serotonin system, ghrelin, and leptin which plays a role in motivation related to healthy eating.
