Final Answer:
The given statement, "Heredity is a chief factor that determines a person's susceptibility to obesity," is true (1) because heredity plays a significant role in determining an individual's susceptibility to obesity due to genetic factors influencing metabolism, fat storage, and appetite regulation.
Step-by-step explanation:
Our genetic makeup significantly impacts how our bodies process and store fat, regulate hunger, and manage energy expenditure. Research shows that certain genes can predispose individuals to obesity by influencing these processes. For instance, variations in genes related to appetite control or metabolism can increase the likelihood of weight gain. However, while genetics may contribute to a predisposition, environmental factors like diet, lifestyle, and physical activity also play crucial roles in determining actual weight outcomes.
It's important to note that while heredity contributes to obesity susceptibility, it's not the sole determining factor. Environmental influences and individual lifestyle choices also significantly impact weight management and overall health. Therefore, a combination of genetic predisposition and environmental factors collectively influences an individual's likelihood of developing obesity.
