Introduction
Given the negative consequences of consistent overconsumption of food (leading to a caloric surplus), having a dietary intake that is of appropriate calorie intake is an important aspect of long-term health. Therefore, thinking about which foods and diets can help promote appropriate satiety to keep calorie intake in check is a key focus for many researchers and practitioners.
There is a complex system of human appetite control. This appetite system influences food consumption and associated motivational drives such as hunger, as well as interacting with and being influenced by energy expenditure. Satiety is an important psycho-biological process involved in the expression of human appetite, inhibiting hunger and intake following food or beverage consumption.
In this episode, the Sigma team discusses the human appetite system, how different nutrients and foods impact satiety, and the implications of this research.

Connection to Previous Episodes
This episode touches on ideas raised in several previous episodes:
- This episode mentioned work on the appetite system from the University of Leeds, done by Dr. Mark Hopkins and colleagues. Dr. Hopkins was on the podcast in episode 299 to discuss the interaction between energy intake and expenditure, including how physical activity impacts appetite and calorie intake.
- The regulation of energy intake was discussed in episode 391, in which Alan and Danny looked at the primary models of body mass regulation.
- In episode 429, Drs. Kevin Hall and Stephan Guyenet discussed two proposed models of obesity pathogenesis: the Carbohydrate-Insulin Model and the Energy Balance Model. In that episode, the central role of the brain in controlling intake was discussed, as well as the impact of food reward and palatability on food intake.
