Final answer:

Step-by-step explanation:
The most important factors contributing to the epidemic of overweight and obesity affecting men, women, and children in all segments of our society are genes, environment, socioeconomic status, and the physical environment.
Genes play a role in determining body weight, but environmental factors such as consuming more calories than expended and limited physical activity also contribute to weight gain. Socioeconomic status can impact food options and affordability, leading some individuals to rely on unhealthy fast food as their primary source of nutrition.
Obesity and weight issues have significant societal costs, including lower life expectancies and higher shared healthcare costs.
