2. **Fast Food and Obesity**
One of the most well-documented effects of fast food consumption is its link to **obesity**. Studies have shown that frequent consumption of fast food is associated with higher calorie intake, weight gain, and increased risk of obesity, especially in children and adolescents.
Why fast food contributes to obesity:
– **Portion sizes**: Fast food portions are often larger than recommended serving sizes, encouraging overeating.
– **Sugary beverages**: Many fast food meals are accompanied by large sodas or milkshakes, which add significant amounts of **empty calories** and sugar.
– **Lack of fiber**: Fast food meals are usually low in fiber, which is essential for maintaining a healthy digestive system and promoting satiety. Without enough fiber, people tend to feel hungry soon after eating, leading to overeating.
