According to research, more than 80% of individuals who lose weight eventually regain it, often within five years. This phenomenon is a key piece of evidence cited by proponents of the set point theory, a concept suggesting that the human body has a genetically predetermined weight range it will fiercely defend through biological mechanisms.

The human body is remarkably adept at regulating its energy stores, with resting metabolism accounting for 60-75% of daily energy expenditure. This sophisticated system, known as energy homeostasis, continuously adjusts the equation of calories consumed versus calories burned to keep the body's energy needs in harmony, protecting against excessive weight fluctuation.

While it's a popular concept, the simplified 'calories in, calories out' model of energy balance is not always true. The human body is a dynamic and complex system that adapts to changes in energy intake and expenditure, making simple arithmetic an unreliable predictor of weight change.

Millions of people worldwide struggle with managing their food intake, highlighting the complexity of our appetite beyond simple physical need. To gain a deeper understanding, it's crucial to know what are the three factors that affect hunger, which involve a complex interplay of the body, mind, and surrounding environment.
