This document discusses the debate around whether fast food or technology is more responsible for the obesity epidemic in America. It reviews research showing that while technology like TV and video games have little direct impact on BMI, fast food consumption is strongly correlated with weight gain and health issues. Fast food restaurants outnumber grocery stores in many low-income neighborhoods, encouraging unhealthy, convenient options. Their misleading marketing of "healthier" high-calorie foods also contributes to the problem. Combined with more sedentary lifestyles, fast food is a major factor driving increased obesity.
