The Science of Hunger

The video explores how hunger is regulated by a complex system of chemicals in the brain and body.

Neurotransmitters like neuropeptide, ghrelin, and leptin play crucial roles in appetite control. The video also discusses how eating habits, such as speed, influence feelings of fullness. Finally, it highlights the biological factors influencing behavior and emphasizes individual uniqueness despite similar internal structures.
