The correct answer is that portion sizes have increased. One common cause of the increasing number of overweight and obese people in the United States is the larger portion sizes offered in restaurants and fast-food chains. To arrive at this answer, one would need to analyze the factors contributing to the rise in obesity rates. Among them, portion sizes have been identified as a significant factor. This is partly due to the cultural shift in eating habits and the desire for value when dining out. Restaurants often serve larger portions to attract customers and make them feel like they are getting more for their money. To further support this answer, one could look at research studies and statistical data that demonstrate the relationship between larger portion sizes and weight gain.
