It encompasses the body's need for energy balance and nutrient supply, while also being shaped by psychological influences such as stress, mood, and the brain's reward system. Theories like the incentive and arousal theories offer insights into the external and internal motivators that govern our eating behaviors, highlighting the complex interplay between our body's signals and our mind's desires.
