ABSTRACT
Appetite is expressed by the tendency to seek food and consume it. Traditionally, it has been thought that appetite is influenced solely by bodily components or by metabolism. These influences are commonly referred to as the glucostatic, aminostatic, thermostatic, or lipostatic hypotheses. Each suggests that a single variable, such as glucose, amino acids, heat generation, or adipose tissue stores, plays the major role in modulating the expression of appetite. It can be accepted that these four variables can be monitored and each can exert some influences over food consumption.
