Final answer:
The important determinants of weight in adult humans include protein intake, physical exercise, and the presence of the hormone CCK in the bloodstream.
Step-by-step explanation:
The important determinants of weight in adult humans include:
- The amount of protein consumed each day: Protein intake can affect weight as it contributes to muscle growth and repair. Additionally, protein-rich foods can increase satiety and help manage appetite.
- The amount of physical exercise a person gets during their leisure time: Regular physical exercise can help burn calories and build muscle, which can aid in weight management.
- The amount of CCK in the blood stream of a person: Cholecystokinin (CCK) is a hormone released in response to food intake. It can play a role in regulating appetite and satiety.
Factors such as the hours of TV viewed per day and family history of anorexia may indirectly influence weight through their impact on lifestyle and eating habits but are not direct determinants of weight.
