Final answer:
The built environment can negatively impact a person's weight through socioeconomic factors that affect food options and physical activity opportunities.
Step-by-step explanation:
The built environment refers to the man-made surroundings that provide the setting for human activity, and it can have a significant impact on a person's weight, especially contributing to obesity. Socioeconomic factors and the nature of neighborhoods can influence the availability and affordability of healthy food options and the safety to engage in physical activities. For instance, a person living in an area with high crime rates may avoid outdoor physical activities such as walking or biking, and if healthy food options are unaffordable or inaccessible, they might rely on cheaper, high-calorie fast food.
