How Does Fast Food Consumption Affect Obesity Rates?

The rise in obesity rates globally is closely associated with the increased consumption of fast food. Epidemiological studies have shown a strong correlation between frequent fast food intake and higher body mass index (BMI). Fast food meals are typically energy-dense and low in nutritional value, promoting excessive calorie intake. This creates an energy imbalance, where calorie intake exceeds energy expenditure, leading to weight gain and ultimately, obesity.
